Dear Mrs. Carlson,
This letter is in reference to a Notice of Violation letter dated December 19, 1997 concerning non-
payment of annual administering and compliance monitoring fee. You were informed in the letter that
your permit would be revoked in 60 days if the annual administering and compliance monitoring fee of
$600.00 was not received during that period. The 60 day period has passed and we have not received your
payment. Therefore, your permit was revoked effective February 17, 1998.
Please be advised that operation of a wastewater treatment system without a valid permit will subject
the owner to a civil penalty of up to $10,000.00 per day. By copy of this letter, I am requesting our
Mooresville Regional Office to confirm that the operation has ceased at this facility, Appropriate
enforcement actions will be initiated for facilities found still to be in operation.
Nothing in this letter should be taken as absolving you of the responsibility for civil penalty
assessments for past or future violations for operation of a wastewater treatment system and/or making a
discharge to the surface waters without a valid permit.
If you have any questions, please contact Cindy Boyles of the Raleigh Central Office Groundwater

FROM: Paul Dahlen P11)
THROUGH: Barbara Christian %
SUBJECT:
NCAC 2L Variance Request
James Farm (Consolidated Freight)
Incident #5484
Priority Rank: 55/B Class: AB
iredell County, N.C.
Background: Five underground storage tanks (one 550-gallon
diesel, one 1,000-gallon gasoline, and three 1,000-gallon
unknown) were removed from this site in November, 1989. To date,
4,100 yds of soil have been removed and remediated through land
application. Monitoring and recovery wells were installed, and a
pump and treat groundwater remediation system was operated during
the following time periods: October 28, 1991-December 17, 1993
and June 1, 1994-September 1, 1994. This remediation has been
effective in reducing groundwater contaminant concentrations.
Since the system has been deactivated, however, contaminant
concentrations have increased in the recovery trench well (RT-1).
Contaminants were not detected in any of the other recovery or
monitoring well samples collected on April, 22, 1996, the last I:),
sampling event. The current BTEX concentration in RT-1 is 1,215 1
parts per million (ppm). The highest BTEX concentration at this
site was 94,900 ppm on February 26, 1992
Receptors: Six water supply wells are located within a .5-
mile radius of the contamination. None of these wells are
downgradient from the contaminant plume, and the closest Well is
approximately 1,200 feet cross -gradient. The closest surface
water body is a pond which is approximately 550 feet downgradient
from the contaminant plume. Given the groundwater flow velocity
of 18 feet/year, any contaminants not naturally remediated would
be expected to reach this pond in approximately 30 years.
NCAC Title 15A 2L .0113 (a,b,c 1-9) provides for a person to
request a variance from the published 2L water quality standards
.0113 Variance
(a) The commission, on its own initiative or pursuant to a
request under G.S. 143-215.3(e), may grant variances to
the rules of this subchapter.

David Hance
August 12, 1996
Page 2
Consolidated Freight sent a request dated May 16, 1996, to DWQ
for a variance through S&ME, Inc. It was received on May 30,
1996, by the Raleigh Central Office (attached).
(b) Requests for variances are filed by letter from the
applicant to the Environmental Management Commission.
The application shall be mailed to the chairman of the
Commission in care of the Director, Division of Water
Quality, Post Office Box 29535, Raleigh, N.C. 27626-
°535.
See (a) above.
(c) The application should contain the following
information:
(1) Applications filed by counties or municipalities
must include a resolution of the County Board of
Commissioners or the governing board of the
municipality requesting the variance.
This item does not apply.
(2) A description of the past, existing or proposed
activities or operations that have or would result
in a discharge of contaminants to the
groundwaters.
None are existing or proposed in the attached variance request
(page 6).
(3) Description of the proposed area for which a
variance is requested. A detailed location map,
showing the orientation of the facility, potential
for groundwater contaminant migration as well as
the area covered by the variance request, with
reference to at least two geographic references
(numbered roads, named streams/rivers, etc.) must
be included.
This item is addressed starting on page 8 of the attached
variance request. Figures 1 and 2 also depict this area.
(4) Supporting information to establish that the
variance will not endanger the public health and
safety, including health and environmental effects
from exposure to groundwater contaminants.
(Location of wells and other water supply sources
including details of well construction within 1/2

mile of site must be shown on a map.
This item is addressed on pages 8-16 (and supporting figures) of
the variance request. Six wells are located within a .5-mile
radius, but all these wells are, cross -gradient from the
contaminant plume.
(5) Supporting information to establish that
requirements of this Rule cannot be achieved by
providing the best available technology
economically reasonable. This information must
identify specific technology considered, and the
cost of implementing the technology and the impact
of the costs on the applicant.
This item is discussed starting on page 17 of the variance
request. Soil excavation and land application and groundwater
pump and treat remediation have been used on this site at a cost
of $286,000. S&ME has demonstrated through analysis of dissolved
oxygen, oxidation-reduction potential, and other parameters, that
bioremediation is most likely occurring. The groundwater
remediation system was deactivated on September 1, 1994, and as
of April 22, 1996, only one well (RT-1) contained measurable
levels of contaminants. Based on a site visit and my review of
the information contained in the site file and the variance
request, I do not believe that this incident poses a threat to
human health.
(6) Supporting information to establish that
compliance would produce serious financial
hardship on the applicant_
This information is provided starting on page 19 of the variance
request.
(7) Supporting information that compliance would
produce serious financial hardship without equal
or greater public benefit.
See (6) above.
(8) A copy of any Special Order that was issued in
connection with contaminants in the proposed area
and supporting information that applicant has
complied with the Special Order.
No. Special Order was issued for this site.

David Hance
August 12, 1996
Page 4
(9) A list of the names and addresses of any property
owners within the proposed area of the variance as
well as any property owners adjacent to the site
covered by the 'variance.
The names and addresses of property owners within and adjacent to
the proposed area of variance and the site are shown on Figure 4
in the variance request. It does not appear as if the NC DOT has
been included as being the owner of the surrounding roads. The
owner of Interstate 77 would also need to be known (Federal or
state DOT).
The following will hopefully answer questions posed in the July
22, 1996 Memo from Arthur Mouberry (attached):
(1) Two of the wells were properly abandoned, and the
abandonment records are on file at MRO. The third well
was never located. Mr. James, the previous owner of
the property, thinks that this well was either removed
or buried during the removal of a house that used to be
on the property. S&ME made several efforts to locate
this well.
(2) (a) The permitted infiltration gallery has not been in
use since September 1, 1994, and there are no
plans for future use. When it was operating, all
reports indicate that it performed as designed.
(b) & (c) All contamination is localized around the
recovery trench. Analyses of samples taken from
monitoring well MW-8, the bedrock well, have
detected only one compound, 1,1,1-trichloroethane,
at a level of 1 part per billion. This was
detected in the June, 15, 1992 sampling event and
has not been detected since. The property line is
located 900downgradient from the area of
contamination according to the variance request.
At a groundwater flow rate of 18 feet/year, it
would take 50 years for any remaining contaminants
to migrate to the closest property line. The
variance request has demonstrated that natural
attenuation is occurring at this site. Continued
monitoring could confirm this.
(d) The infiltration gallery is not being used, nor
will it be used.

David Hance
August 12, 1996
Page 5
(3) I calculated a flow rate of 16.68 feet/year using their
figures.
(4) None that I am aware of other than the Director
changing the groundwater classification designation.
DiscussiCn: Based on the well survey, this site is a Class AB
site. Soil vapor extraction could possibly remove contamination
from the soil that is causing a rise in groundwater contaminant
levels when the system is not running. Further assessment would
have, to be completed, however, to determine the location
of the contaminated soil before SVE wells could be placed. By
installing and operating an SVE system combined with continued
pumping and treating of the groundwater, the groundwater
contaminant levels might be reduced, It is unknown, however, what
level of reduction in contaminant concentrations would be
achieved, nor whether the reduction would be more than the
anticipated reduction through natural attenuation.
Based on the information contained in the variance request,
I recommend approval of this variance request with the
stipulation that groundwater monitoring will continue over a
period of at least 2 years to ensure that natural attenuation is
occurring.
If you have any questions, please call me at [phone], ext.

15A NCAC 2L, Groundwater Classifications and Standards. A REVIEW
BOVNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
concentration of any substance equals or exceeds the maximum allowable
concentration of that substance at the REVIEW BOUNDARY, as determined by
monitoring, the permittee shall either (i) demonstrate, through predictive calculations
or modeling, that natural site conditions, facility design and operational controls
will prevent a violation of standards at the Compliance Boundary; or, (ii) submit a
plan for the alteration of existing site conditions, facility design or operational
controls that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
All components of the groundwater recovery, treatment, and disposal system shall
be properly weather -proofed to prevent freezing and failure of the system..

3. The influent and effluent from the treatment system shall be sampled once every two

GROUNDWATER REMEDIATION SYSTEM IMPLEMENTATION COSTS
The following estimated costs are for installation of the
proposed groundwater restoration system outlined in the RAP. This
system would involve the removal, treatment and re -infiltration of
groundwater. The dissolved hydrocarbons in the groundwater would
be removed via a recovery trench and 2 recovery wells drilled
further downgradient of monitor well BMW-1, as indicated in the
RAP. The trench would be installed in the bottom of Tank Pit #1,
as also indicated in the RAP. The groundwater would be treated on -
site via an on -site air stripping tower and then discharged into
an on -site upgradient infiltration gallery, since there are no
sanitary or storm sewers in the site area. As demonstrated in the
RAP, the proposed groundwater recovery system will effectively
capture all treated effluent discharged from the infiltration
gallery and the entire hydrocarbon plume. This recycling of
treated groundwater will also enable flushing of any remaining
adsorbed hydrocarbons in the saturated zone beneath Tank Pit 1.
The groundwater treatment system will be installed by
Westinghouse Groundwater Recovery (WGR) of Atlanta Georgia and
Westinghouse Environmental and Geotechnical Services, Inc. of
Charlotte, North Carolina personnel, in accordance with all
regulations and directives contained in OSHA 29, CFR Chapter
XVIII, Section 1910.120. The extraction system will consist of
three (3) WGR Groundwater Depression Pumps, pneumatic controllers,
and at grade locking well vault with air/product vaiving. The
treatment system will include an air stripping tower with blower,
275-gallon staging tank, transfer pump, totalizing flow meter, and
two combination motor starters for the blower and transfer pump.
These, components will be mounted on an epoxy coated steel skid.

The staging tank will be equipped with a mercury level float switch
which will activate the transfer pump and blower when water in the
tank reaches a predetermined level, and deactivate when the water
has dropped.
The treatment system will require a 240/480 VAC 3 0, 60 amp
electrical service. All electrical work will be performed by a
North Carolina licensed subcontractor whom is familiar with the
code requirements in the Statesville area. All above ground and
below ground utilities in the area have been located by ULOCO,
Ticket No's. 318849 and 81111.
The Westinghouse technicians will install the previously
described equipment, as outlined in the RAP and will install
influent and effluent piping below grade. Upon completion of
system installation, Westinghouse personnel will start-up and
troubleshoot the system. Installation and start-up of the
treatment system is estimated to take 2 weeks, providing favorable
weather conditions.
Power supply, site preparation, and installation of security

Dear Mr. Floyd:
Attached please find a copy of the second Method 6230D
analytical results of samples collected at the influent (sample
port 1) and the effluent after the 2nd carbon unit (sample port 6),
as required by the referenced permit. The two samples were
collected on November 13, 1991. The effluent results indicate
below 15A NCAC 2L levels for all Method 6230D volatile organic
compounds, except benzene, which was detected at 1.3 ug/L. The
state "action" or compliance level for benzene per 15A NCAC 2L
.0200 is 1 ug/L. Additional volatile organic concentrations
detected at sample port 6, which are below 15A NCAC 2L levels were
chlorobenzene at 4 ug/L, ethyl benzene at 3.3 ug/L, toluene at 7.1
ug/L and total xylenes at 14.4 ug/L. The 15A NCAC 2L compliance
levels for these compounds are 300 ug/L for chlorobenzene, 29 ug/L
for ethyl benzene, 1000 ug/L for toluene and 400 ug/L for total
xylenes. The detection limit used for Method 6230D compounds is
1.0 ug/L, as reported on the analytical results. A copy of the

Mr. Jack Floyd

sample chain of custody is attached.
Mr. Arlen Burney of the Mooresville Regional Office of the
North Carolina Department of Environment, Health and Natural
Resources (NCDEHNR) was contacted by telephone on December 4, 1991
regarding the 1.3 ug/L benzene concentration in the effluent
sample. The phone call was made within 24 hours of receipt of the
laboratory report, per the permit #WQ0405069 requirements.. We
informed. Mr. Burney that the volatile organic concentrations in the
effluent are believed to be due to high fluctuations in flow rates
through the two carbon units, which reduce the contact time between
the carbon and volatile organic compounds detected. During
sampling on November 13, 1991, the flow rate through the two carbon
units was measured at approximately 13 gpm. This flow rate is not
discharged continuously to the infiltration gallery, but rather
periodically (i.e. during removal of approximately 150 gallons of
air stripped water out of the second holding tank). The total
daily discharge of treated water to the infiltration gallery is
approximately 2160 to 2880 gpd or 1.5 to 2 gpm, which is below the
permitted discharge of 4320 gpd.
To resolve this problem, Westinghouse reduced the flow rate
through the two carbon units to 6 gpm. This will increase contact
time from 8 minutes at 13 gpm to 15 minutes at 6 gpm. Therefore,
this increased contact time should reduce benzene concentrations to
below 1 ug/L. The influent and effluent were re -sampled for Method
6230D analysis on November 26, 1991 after reducing the flow rate.
Laboratory results will be submitted to the NCDEHNR within 1 month
of sample collection.
The carbon usage rate is approximately 1.5 lbs./day based on
Carbtrol calculations of the Method 6230D analyses for water
sampled from sample port SP3 an 'November 5, 1991. Therefore, the

Mr. Jack Floyd
Page 3
December 6, 1991
expected life of the first carbon unit in series is approxia
130 days. Periodic monitoring of BTEX before and after the first
carbon unit (i.e. sample ports SP4 and SPS) will be performed to
evaluate when breakthrough occurs and time for replacing carbon
canisters.
Bi-weekly sampling will continue for the first three months
and then sampling of SP1 and SP6 will be performed on a monthly
basis.
At present, the treatment system is down due to a defective
control sensor for the high water level switch for transfer pump 1.
A new sensor has been ordered and will be installed as soon as it
is delivered.
If you have any questions, or need additional information,
please do not hesitate to call.

and may be rescinded unless the facilities are installed, maintained, and operated in a
manner which will protect the assigned water quality standards of thesurface waters
and ground waters.

4. In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including
those as may be required by this Division, such as the construction of additional or
replacement treatment or disposal facilities.
5. The issuance of this permit shall not relieve the Permittee of the responsibility for
damages to surface or groundwaters resulting from the operation of this facility.
b< Any sludge generated from these treatment facilities must be disposed of in
accordance with General Statute 143-215.1 and in a manner approved by the North
Carolina Division of Environmental Management.
Diversion or bypassing of the untreated groundwater from the treatment facilities is
prohibited.
I P RATION ,ANI MAINTENANCE, REQUIREMENTS

Upon classification of the facility by the Certification Commission, the Permittee
shall employ a certified wastewater treatment plant operator to be in responsible
charge of the wastewater treatment facilities.. The operator must hold a certificate of
the type and grade at least equivalent to the classification assigned to the wastewater
treatment facilities by the Certification Commission. Once the facility is classified,
the Permittee must submit a letter to the Certification Commission which designates
the operator in responsible charge within thirty days after the wastewater treatment
facilities are 50% complete.
3. The facilities shall be effectively maintained and operated as a non -discharge system
to prevent the discharge of any wastewater resulting from the operation of this
facility.
III. MONITORING AND REPORTING REOUIREMENTS

of the influent to such station or facility,
d. Any time that self -monitoring information indicates that the facility is not in
compliance with its permit limitations.
Persons reporting such occurrences by telephone shall also file a written report in
letter form within 15 days following first knowledge of the occurrence. This report
must outline the actions taken or proposed to be taken to ensure that the problem
does not recur,
IV. GROUNDWATER REQUIREMENTS,
1, The compliance Boundary for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. An exceedance of
Groundwater Quality Standards beyond the Compliance Boundary is subject to
penalty provisions applicable under General Statute 143-215.6(1)a. The sale of
property, by the Pen-nittee, which is within or contiguous to the disposal system site
may alter the location of the Compliance Boundary.
For facilities permitted on or after December 30, 1983, the Compliance Boundary is
established at the lesser of 250 feet from the infiltration gallery, or 50 feet within
the property boundary.
If the title to any property which may affect the location of the Compliance Boundary
is changed, the Permittee shall notify the DEM Director within 14 days. The
Director shall then establish a modified Compliance Boundary which will be done as
a modification to the Permit.
The REVIEW BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. A .REVIEW
BOUNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
concentration of any substance equals or exceeds the maximum allowable
concentration of that substance at the REVIL•W 1301..ND/NRY, as determined by
monitoring, the permittee shall either (i) demonstrate, through predictive calculations
or modeling, that natural site conditions, facility design and operational controls
will prevent a violation of standards at the Compliance Boundary; or, (ii) submit a
plan for the alteration of existing site conditions, facility design or operational
controls that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
All components of the groundwater recovery, treatment, and disposal system shall
be properly weather -proofed to prevent freezing and failure of the system.

3. The influent and effluent from the treatment system shall be sampled once every two
(2) weeks for the first three (3) months and monthly thereafter for the parameters
specified below:
Volatile Organic Compounds - by Method 1 or Method 2 below
Method 1: Method 6230D ( Capillary - Column), "Standard Methods for the
Exarnination of Water and Wastewater", 17th edition, 1989
Method 2: Method 502.2 "Methods for the Determination of Organic
Compounds in Drinking Water", United States Environmental
Protection Agency - 600/4-88/039
If any volatile organic compounds are detected by method 6230D, or the equivalent
method 502.2, then EPA methods 604 and 611 must also be run to detect other
organic compounds which may be present. The results of all analyses specified in
the monitoring requirements, including 604 and 611 if required, must be submitted
simultaneously.
The results of the sampling and analysis shall be sent to the Groundwater Section in
the Mooresville Regional Office and to the Groundwater Section, Permits Unit, Post
Office Box 27687, Raleigh, N. C. 27611-7687, within 30 days of sample
collection.
4. Two (2) weeks prior to system start-up, the Permittee shall notify the Division of
Environmental Management's Mooresville Regional Office that operation is about
to commence.
5. The groundwater recovery treatment and disposal system shall be inspected weekly.
If it is determined that the system is malfunctioning, all repairs should be made as
soon as possible and reported to the Mooresville Regional Office.
6. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
7. The three inactive water supply wells located at the remediation site shall be properly
abandoned in accordance with 15A NCAC 2C .0113.
8 As specified in the submittal information, dual carbon adsorption units in series will
be provided to treat the effluent prior to discharge into the infiltration gallery.
9. The concentration of contaminants within the effluent that is discharged into the
infiltration gallery shall not exceed those levels specified in 15A NCAC 2L .0202,
"Classifications and Water Quality Standards Applicable to the Groundwaters of
North Carolina,"
INSPEC IONS
Adequate inspection, maintenance and cleaning shall be provided by the Perrnittee to
insure proper operation of the subject facilities,
4

2, The Permittee or his designee shall inspect the groundwater recovery and treatment
facilities to prevent malfunctions and deterioration, operator errors and discharges
which may cause or lead to the release of wastes to the environment, a threat to
human health, or a nuisance. The Permittee shall keep an inspection log or summary
including at least the date and time of inspection, observations made, and any
maintenance, repairs, or corrective actions taken by the Permittee. This log of
inspections shall be maintained by the Permittee for a period of three years from the
date of the inspection and shall be made available upon request to the Division of
Environmental Management or other permitting authority,
Any duly authorized officer, employee, or representative of the Division of
Environmental Management may, upon presentation of credentials, enter and inspect
any property, premises or place on or related to the disposal site and facility at any
reasonable time for the purpose of deterrnining compliance with this permit; may
inspect or copy any records that must be kept under the terms and conditions of this
permit; or may obtain samples of groundwater, surface water, or leachate.
VI. GENERAL CONDITIONS
This permit shall become voidable unless the facilities are constructed in accordance
with the conditions of this permit, the approved plans, specifications and other
supporting data.
2. This permit is effective only with respect to the nature and volume of wastes
described in the application and other supporting data.
This permit is not transferable. In the event there is a desire for the facilities to
change ownership, or there is a name change of the Permittee, a formal permit
request must be submitted to the Division of Environmental Management
accompanied by an application fee, documentation from the parties involved, and
other supporting materials as may be appropriate. The approval of this request will
be considered on its merits and may or may not be approved.
4. The Permittee shall obtain a well construction permit from the Mooresville Regional
Office prior to construction of the recovery wells.
Prior to a transfer of this land to a new owner, a notice shall be given to the new
owner that gives full details of the materials applied or incorporated at this site.
6. A set of approved plans and specifications for the subject project must be retained
by the Permittee for the life of this project.
7. Failure to abide by the conditions and limitations contained in this permit may subject
the Permittee to an enforcement action by the Division of Environmental
Management in accordance with North Carolina General Statute 143-215.6.
The annual administering and compliance fee must be paid by the Pennitree within
thirty (30) days after being billed by the Division, Failure to pay the fee accordingly
may cause the Division to initiate action to revoke this permit as specified by 15
NCAC 211,0205 (c)(4).
9. The issuance of this permit does not preclude the Permittee from complying with any
and all statutes, rules, regulations, or ordinances which may be imposed by other
government agencies (local, state, and federal) which have jurisdiction.

S&ME, Inc. Project No. 1354-89-413A
Dear Mr. Floyd:
Attached is a copy of the ninth set of Method 601 and 602
analytical results of samples collected at the influent (sample
port 1) and at the effluent after the second carbon unit (sample
port 6), as required by the referenced permit. The two samples
were collected on April 8, 1992.
The effluent sample results indicate below quantitation limits
(BQL) of volatile and semivolatile organic concentrations by EPA
SW-846 Methods 601 and 602; therefore, none of the analyte
concentrations exceeded the 15A NCAC 2L standards or permit
discharge levels. Analyses of the influent revealed concentrations
of benzene (200 ug/Z), ethyl benzene (28 ug/E), toluene (750 ug/t),
total xylenes (650 ug/t) and 1-2 dichloroethane (3 ug/E), resulting
in a total volatile hydrocarbon concentration of 1631 ug/t.
Total flow through the treatment system, as of April 29, 1992,
was 325,465 gallons. The pumping rate from recovery trench well
RW-1 was increased from 1.5 gpm to approximately 4 gpm. The
average total pumping rate for the three recovery wells is

Mr. Jack Floyd

approximately 5 gpm or 7200 gpd. Permission to increase the total
pumping rate from 4320 gpd to 8640 gpd was granted by you during
our April 13, 1992, phone conversation, provided the treatment
system and infiltration gallery could effectively assimilate the
greater recharge rate.
The groundwater treatment system is effectively reducing
dissolved hydrocarbon concentrations to below quantitation limits
and the infiltration gallery is effectively assimilating the
greater discharge rate. The depth to water from ground surface in
monitor well MW-3 (adjacent to infiltration gallery) was 25.12
feet. This illustrates that the mound of water beneath the
infiltration gallery has only increased approximately 1.5 feet
above the level measured before increasing the discharge rate by 2
gpm. Total height of the mound is approximately 4.5 feet. It
appears that the infiltration gallery could effectively handle even
greater recharge rates, if needed.
The air stripper and carbon units together are presently
operating at a greater than 99.9% removal rate efficiency.
No leaks or malfunctions, which would adversely affect
hydrocarbon removal efficiencies have been detected in the
remediation equipment. All fail safe switches and level sensors
are in good working order. The infiltration gallery is working
satisfactory, as no abnormally high water levels have been recorded
in either infiltration gallery monitor well IG-1 or monitor well
MW-3.

will consist of two carbon adsorption units in series, as indicated
in the attached proposal from Carbtrol. Each carbon unit alone is
designed to remove contaminants to levels below 15A NCAC 2L.0202
standards. Effluent from the air stripper will be gravity fed into
a second, 275-gallon holding tank. To prevent overspilling, the
holding tank will be equipped with high and low water level sensors
(LS-04), which will be connected to a 1/2 hp transfer pump. Either

sensor will deactivate the second transfer pump if water levels
become unacceptable. In addition, failure of the second transfer
pump will automatically shut off the entire groundwater treatment
system. The treated water in the holding tank will then be pumped
at a rate of approximately 3 gallons per minute by a 1/2 hp NPE
transfer pump (non -explosion) into the two Carbtrol, granular
activated carbon canisters (L-1 model). Transfer pump and carbon
canister specifications are provided herein. Operating pressure
for the two carbon units will be approximately 10 psi. Each carbon
unit will contain 200 lbs. of granular activated carbon. Treated
groundwater from the two carbon canisters will then be gravity fed
into the infiltration gallery described in Section 3.7 of the RAP.
Figure 1 provides a schematic layout of these additional
groundwater treatment components.
Carbtrol has calculated the theoretical carbon usage rate to
be approximately 0.3 lbs. per day. Carbon canister life (200 lbs.
carbon) is estimated to be greater than 365 days. This rate is
based on our estimated "worst case" hydrocarbon concentrations in
the effluent (after air stripping), as indicated in Appendix IV of
the RAP. The carbon usage rate is expected to decrease over time
as less contaminated groundwater enters the groundwater treatment
system. Carbtrol states that their carbon adsorption canisters
will remove hydrocarbons at a removal rate of greater than 99.99%.
Therefore, the carbon canisters will treat the groundwater to below
15A NCAC 2L.0202 levels. As indicated in "Groundwater Remediation
and Petroleum" by David Noonan and James Curtis (Lewis Publishers,
1990) removal efficiencies of >99.99% for gasoline compounds in
groundwater are typical for granular activated carbon units.
The totalizing flowmet r, as indicated in Figure 17 of the RAP
will be moved from the influent manifold before the first surge
tank to before the two carbon canisters after the air stripper,

Mr. Randy Jones

August 16, 1991
Additional groundwater sampling ports will be installed to
permit retrieval of water samples before the first carbon canister
(SP-05), in between the two canisters (SP06) and after the two
canisters (SP-07). Analyses of samples from these ports will allow
for evaluating carbon usage rates and predicting possible
breakthrough time for the first carbon canister (estimated at
approximately 1 year by Carbtrol). The first carbon unit will be
replaced with the second carbon unit after 1 year of groundwater
pumping or when hydrocarbons are detected in the sample port
between the two carbon units. The spent carbon canisters will be
shipped back to Carbtrol to be reactivated by a fully licensed
reactivator and recycler. A new carbon canister will be ordered
and placed on-line during removal of the first spent canister, so
as to ensure two carbon units in series at all times. Operation
of the two carbon units in series provides a high degree of
assurance that 15A NCAC 2L.0202 standards will not be violated.
Groundwater from these three sampling ports will be analyzed
for Class I hydrocarbon compounds by EPA Methods 601, 602, EDB,
MTBE and IPE. Groundwater from the first and middle sampling ports
will be collected for analysis on a quarterly basis. Groundwater
from the last sampling port will be collected for analysis on a
weekly basis for the first month of system operation and then
monthly thereafter, as mentioned in the RAP.
System Weatherproofing
All above ground components of the recovery, treatment and
infiltration gallery system including all water tanks and pipes
will be weatherproofed with fiberglass insulation. All below
ground lines will be buried 1 to 2 feet below ground. These
measures have proven to be satisfactory on other systems currently
in operation.

We would greatly appreciate your prompt review of this RAP
addendum. As per your verbal approval during our August 8, 1991
phone conversation, we are proceeding with installation of the
proposed groundwater recovery system consisting of two recovery
wells, one recovery trench and the infiltration gallery, as no
objections or comments were made relative to the design and
locations of these system components. We will not start up the
system, however, until we have received the Non -Discharge Permit.
A well permit from the Mooresville Regional Office of the NCDEI-INR
to construct the proposed recovery wells was issued on April 15,
1991 (Well Construction Permit No. 48-0235-WR-0094). If you have
any questions, comments or need additional information, please
call.

WQ0005069/GW91145
(Randy Jones: DEM SERG Rev±ew Engineer)
'he Groundwater Section has reviewed the subject permit
application and recommends that the permit contain the following
conditions:
1. The three (3) inactive water supply wells located at
the remediation site shall be properly abandoned in
accordance with 15A NCAC 2C .0113.
2, A carbon adsorption unit shall be employed to further
treat the effluent prior to discharge into the
infiltration gallery.
The concentration of contaminants within. the effluent.
discharged into the infiltration gallery shall not
exceed those levels specified in 15A NCAC 2L .0202,
CLASSIFICATIONS AND WATER QUALITY STANDARDS APPLICABLE
TO THE GROUNDWATERS OF NORTH CAROLINA.
4 All components of the groundwater recovery, treatment
and disposal system shall be properly weather -proofed
to prevent freezing and failure of the system.
The influent and effluent from the treatment system
shall be sampled once every two (2) weeks for the first
three (3) months and monthly thereafter for the
parameters specified below:

Volatile Organic Compounds - (by method 1 or 2
below)
Method 1: Method 6230D (Capillary - Column), "Standard
Methods For The Examination of Water and
Wastewater", 17th ed., 1989
Method 2: Method 502.2 "Methods For The Determination
Of Organic Compounds In Drinking Water", U.S.
EPA - 600/4-88/039
If any volatile organic compounds are detected by
method 6230D, or the equivalent method 502.2, then EPA
methods 604 and 611 must also be run to detect other
organic compounds which may be present. The results of
all analyses specified in the monitoring requirements,
including 604 and 611 if required, must be submitted
simultaneously.
The results of the sampling and analysis shall be sent
to the Groundwater Section in the Mooresville Regional
Office and to the Groundwater Section, Permits Unit,
P.O. Box 27687 Raleigh, N.C. 27611-7687 within 30 days
of sample collection.
6. Two (2) weeks prior to system start-up, the Permittee
shall notify the Division of Environmental Management,
Mooresville Regional Office, that operation is about to
commence.
7. The groundwater recovery, treatment and disposal system
shall be inspected weekly. If it is determined that
the system is malfunctioning, all repairs should be
made as soon as possible and reported to the
Mooresville Regional Office.
The QflpCompliance Boundar for the disposal system is
specified by regulations in 15A NCAC 2L, Groundwater
Classifications and Standards. An exceedance of
Groundwater Quality Standards beyond the Compliance
Boundary is subject to the penalty provisions
applicable under General Statute 143-215.6(1)a. The
sale of property, by the Permittee, which is within or
contiguous to the disposal site, may alter the location
of the Compliance Boundary.
For facilities permitted on or after December 30, 1983,
the Compliance Boundary is established at the lesser of
250 feet from the infiltration gallery, or 50 feet
within the property boundary.
If the title to any property which may affect the
location of the-4 Compliance Boundary is changed, the
Permittee shall notify the DEM Director within 14 days.

The Director shall then establish a modified Compliance
Boundary which will be done as a modification to the
Permit.
The REVIEWBOONDARY for the disposal system is
specified by regulations in 15A NCAC 2L, Groundwater
Classifications and Standards. A REVIEW BOUNDARY is
established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste
disposal area. When the concentration of any substance
equals or exceeds the maximum allowable concentration
of that substance at the REVIEW BOUNDARY, as determined
by monitoring, the permittee shall either (i)
demonstrate, through predictive calculations or
modeling, that natural site conditions, facility design
and operational controls will prevent a violation of
standards at the Compliance Boundary; or, (ii) submit a
plan for the alteration of existing site conditions,
facility design or operational controls that will
prevent a violation of standards at the Compliance
Boundary, and implement that plan upon its approval by
the Director.
9. Any groundwater quality monitoring, as deemed necessary
by the Division, shall be provided.

INTRODUCTION
A Site Assessment, in accordance with North Carolina
Department of Environment, Health and Natural Resources (NCDEHNR)
guidelines was submitted on behalf of Consolidated Freightways in
September 1990. Laboratory analyses of sail and groundwater
samples taken during the Site Assessment indicates that the
hydrocarbon present is primarily gasoline. This Remedial Action
Plan (RAP) proposes the installation of a pump and treat system to
mitigate the on -site groundwater contamination and prevent further
migration of dissolved contaminants. The Remedial Action System
will include one recovery trench, two groundwater recovery wells,
an air stripping tower and infiltration gallery. In order to
further abate residual hydrocarbons detected beneath the shallow
water table in Tank Pit 1, additional excavation of contaminated
soils will be performed during installation of the recovery trench.
These soils (estimated 50 cubic yards) will either be landfarmed
in conjuction with the excavated soils discussed in the July 31,
1990 "Non- Discharge Permit Application" or incinerated at a state
approved brickyard facility.
The conceptual design of the plan. reflects the site's rural
setting and associated wastewater disposal limitations.
Groundwater, recovered at the recovery trench and recovery wells,
will be treated via air stripping and discharged to an infiltration
gallery. This capture, treatment, and infiltration process will
also reduce minor adsorbed hydrocarbon concentrations within the
saprolite that extend slightly downgradient of Tank Pit 1.
1.1 FACILITY LOCATION, DESCRIPTION AND LAND USE
The James Fargi site (Figure 1) is located north of the
Interstate, I-40 and west of I-77 on James Farm Road. On a portion
of the USGS quadrangle map of Statesville, Iredell County, the site
is located at Lat. 35844'10" N. and Long. 30°5200" W. The site
lies at an elevation of approximately 900 feet above mean sea level

and slopes to the west (Figure 2). On -site elevation differences
range between 824 to 924 feet above sea level. The site is located
within the upper Piedmont Belt of the Charlotte Geologic Belt. At
present, the site is undeveloped farmland, which has been used as
a dairy farm for over 50 years. Land use within a 0.5 mile radius
is predominantly undeveloped with some scattered commercial.
development to the south and west and residential development to
the north and west. The closest downgradient surface water body
is located approximately 700 feet west of Tank Pit 1.
1.2 FACILITY HISTORY
Three underground storage tanks (USTs) were formerly located
in Tank Pit 1. These tanks consisted of one, 1000-gallon gasoline
tank, and two, l000-gallon tanks of unknown fuel. All tanks,
piping and dispensers were removed in November 1989 along with an
estimated 2500 cubic yards of contaminated soil. An additional 300
cubic yards of contaminated soil was removed from Tank Pit 1 in
June 1990, as requested by the NCDEHNR. One 1,000 -gallon diesel
UST and 1300 cubic yards of contaminated soil were removed from
Tank. Pit 2 between November, 1989 and June 1990, as discussed in
the Site Assessment. A Site Assessment was not required by the
NCOEHNR for Tank Pit 2. All contaminated soil was removed from
Tank Pit 2, and no groundwater contamination was found in
downgradient monitor well BMW-2.
1.3 ENVIRONMENTAL ASSESSMENT SUMMARY
Constituents of the Class 1 gasoline analytical group were
detected in the groundwater beneath Tank Pit 1. Free product was
not detected in any boring, monitor well or excavation. The soil
and groundwater contamination are confined to an area around Tank
Pit 1. No hydrocarbons were found to have penetrated the dense
"bedrock" encountered at 46 feet below grade. This was evidenced
by the below quantitation levels (BQL) of purgeable halocarbons
(EPA Method 601), purgeable aromatics (EPA Method 602) and
base/neutral extractables (EPA Method 625) in groundwater sampled
from the downgradient bedrock monitor well MW-8, as referenced in
1-?

the November 26, 1990 Addendum to the Site Assessment of September
13, 1990. No vertical component of groundwater flow has been
measured on -site and no major geologic faults or fracture systems
have been identified by the United States Geological Survey. The
horizontal and vertical extent of hydrocarbons at Tank Pit 1 have
been fully defined. The Site Assessment Report and Addendum were
approved by the North Carolina Department of Environment, Health
and Natural Resource's Groundwater Section, as mentioned in their
December 10, 1990 letter to the former owner of the site Mr. N.C.
James. Detailed hydrogeologic and analytical data are included in
sections 3.1 and 3.2 of this report.
No active drinking water supply wells exist within a 0.5 inile
radius of the site. Three inactive drinking water wells exist on -
site, of which, one is located approximately 250 feet southwest of
Tank Pit 1. The other two inactive drinking water wells are
located approximately 250 feet northeast of Tank Pit 1 and
approximately 115 feet north of Tank Pit 1. The closest
downgradient water well is located approximately 2 miles west of
the site. However, this well is also inactive.
1.4 REMEDIAL ACTION PLAN OBJECTIVES
The main objective of the Remedial Action Plan is to use a
pump and treat system to capture and remove the dissolved
hydrocarbon plume and prevent further migration of dissolved
hydrocarbons. The following objectives will be used to obtain this
main objective: 1.) to use an air stripping tower and surge tank
to reduce contaminant concentrations to acceptable state regulatory
levels, 2.) to use a remediation design that, to the extent
feasible, will not disrupt the natural subsurface environment or
future site operations, and 3.) to install a system which maximizes
safety to the public and system personnel during operation and
contains inherent design components to minimize the possibility of
unauthorized release to the environment (fail safe mechanisms).
The complemented use of an infiltration gallery, a recovery trench
and two recovery wells will provide the abatement of dissolved and
1-3

adsorbed hydrocarbons fro he surface in an e .editions antler.
Given the low hydraulic conductivity and transmissility of the
water table aquife , a recovery trench and two recovery wells are
proposed to obtain maxi p n ing rates and to ensure capture of
the dissolved hydrocarbon plume. An a lent infiltration
gallsrY will recirculate treated groundwater to the ecove trench
and recoveryre.s to maxi aa le pumping rates and to help flush the
traces of residual hydrocarbons from the sell.

2 SOIL REMEDIATION
A "Non -Discharge Permit Application" (submitted to the NCDEHNR
on July 31, 1990) for land farming of the 4100 cubic yards of
contaminated soil removed from Tank Pits 1 and 2 was approved by
the Division of Environmental Management, Permits and Engineering
Unit on September 14, 1990 (Permit # WQ000398). The associated
Erosion Control Plan incorporated into the "Non -Discharge Permit
Application" was approved by the NCDEHNR Land Quality Section on
October 16, 1990. The erosion control plan devices have been
constructed and the contaminated soil was land applied on -site, as
per the permit requirements between November 20-22, 1990. The
first soil sampling event of the landfarmed area is set for
January 28, 1990 (eight weeks after initial disposal and four
tilling events).
Soils excavated during recovery trench installation will be
screened with an organic vapor analyzer. One soil sample per 80
cubic yards of soil at the bottom of the trench excavation will be
analyzed for total petroleum hydrocarbons (TPH). Soils with TPH
concentrations above 10 ppm will be disposed of in the most cost
effective manner. Depending on soil volume and TPH results, the
soils will either be treated on -site via land farming with the
other stockpiled soils or transported for incineration. A
corrective action plan in accordance with federal register 40 CFR
280.66 will be submitted to the NCDEHNR for any additional
contaminated soils excavated. If the land application method
becomes the treatment method of choice, permission to treat soils
in this manner will be sought in the form of an amendment to the
existing Non -discharge Permit No. WQ0003980.
Excavation of contaminated soil during installation of the
recovery trench will facilitate removal of the highest
concentrations of adsorbed hydrocarbons in the bottom of Tank Pit
1. Total petroleum hydrocarbons in soils beneath 10 feet below
2-1

grade at monitor wells B 1 and MW 7 ranged between 9 and 16
mg/kg, and are therefore considered to not merit remediatinn„
Residual hydrocarbon concentrations present in the soil after
trench installation will be treated by fleshing during groundwater
extraction and infiltration.

GROUNDWATER REMEDIATION
3.1 HYDR©GEOLOGIC PROFILE
The geologic profile for the site (illustrated in Figures 3
and 4) consists of a micaceous silt with interbedded slightly sandy
to sandy silt and clayey silt layers to 43 feet below grade. A
thin (3 feet thick) clayey sand layer was encountered from 43 to
46 feet below grade. A very dense bedrock layer consisting of a
micaceous (biotite) garnetiferous granitic gneiss was encountered
at 46 feet below grade. The bedrock was cored at MW-8 to 51 feet.
The upper 2 feet of the bedrock core indicated no fractures, as it
cored well. The bottom 4 feet of the bedrock core revealed
possible fractures, as it collapsed after coring. The sand grains
range from fine to medium in size, subangular to rounded, and
moderately to poorly sorted.
Groundwater was encountered at approximate depths of 25 to 35
feet below grade. Groundwater level data collected on August 5,
1990 are compiled in Appendix III of the Site Assessment. Figure
5 illustrates the natural groundwater flow at Tank Pits 1 and 2 on
August 8, 1990. Groundwater levels indicate that the horizontal
groundwater flow is towards the southwest following the slope of
subsurface topography towards the topographic low on -site. The
average groundwater gradient is approximately 0.012 ft./ft. Water
level measurements from the deep monitor well imply that the
aquifer is unconfined with no apparent vertical gradient.
Preliminary liquid levels in standpipes placed in borings B-1
through B-4 also indicated that groundwater flow was to the
southwest.
Hydraulic conductivities calculated from bail tests performed
in monitor wells MW-3, MW-4, MW-5, MW-6 and MW-7 revealed an
average hydraulic conductivity of 0.8 feet/day (See Site Assessment
Report for calculations). This value is typical for the sediments
encountered. Based on information referenced in the Site
3-1

Assessment the specific yield or unconfined storativity of the
unconfined aquifer is estimated to be 1 x 10'1as referenced by
Driscoll, 1986.
The average transmissivity (T) for the screened interval of
the shallow unconfined aquifer can be calculated using the Theis
equation T = Kb, where K is the hydraulic conductivity, and b is
the saturated thickness of the aquifer (15 to 20 feet). Therefore,
by calculation, the transmissivity of the shallow unconfined
aquifer, T, equals 12-16 ft2/day. The underlying aquitard of the
aquifer is considered to be the "bedrock" at 46 feet below grade.
Utilizing the average hydraulic conductivity and gradient as
well as an estimated porosity (n = 0.35), the horizontal
groundwater flow velocity was evaluated using Darcy's Law
(Driscoll) to be 0.03 feet/day or 10 feet/year.
The underground water supply line located approximately 100
feet west of Tank Pit 1 is not deep enough to effect the migration
and transport of dissolved hydrocarbons in the groundwater. None
of the wells are screened through any confining layers or through
the bedrock, and therefore, do not contribute to hydrocarbon
movement.
3.2 CONCENTRATIONS AND EXTENT OF HYDROCARBONS
All soil quality data is provided in the Site Assessment
Report. Figure 6 illustrates the horizontal extent of contaminated
soils beneath Tank Pit 1. This figure shows that the areal extent
of contaminated soils is confined to Tank Pit 1 and slightly
downgradient around BMW-1 and MW-7. Contaminated soil outside of
Tank Pit 1 is believed to be of minor (<16 ppm TPH) concentrations.
Soil sampled from MW-8 at 30 feet below grade (water table
interface) revealed below quantitation limits of TPH, as reported
in the November 26, 1990 Addendum. TPH concentrations in composite
soil samples collected by Bold Research Labs, Inc. from all four
walls of Tank Pits 1 and 2 were below 5 mg/kg. Therefore, no
3 -2

additional sampling along the walls of both Tank Pits 1 and 2 was
requested by the NCOEHNR. Organic vapor concentrations in all
soils sampled from the six test borings and monitor wells MW-3, MW-
4, MW-5 and MW-6 revealed 0 ppm on the OVA. Organic vapors
measured in soils at MW-7 ranged from 0 to 1 ppm in the unsaturated
zone and from 0 to 30 in the unsaturated zone. The horizontal and
vertical components of plume geometry are superimposed on the two
aquifer cross sections (Figures 10 and 11).
The vertical extent of contaminated soils has been defined at
BMW-1, MW-7 and MW-8. TPH concentrations at MW-1 were between 10
to 84 mg/kg in the unsaturated zone (10 mg/kg avg.) and between 9
to 10 mg/kg in the saturated zone. A soil sample from MW-7 was
found to contain 15.7 mg/kg semi-volatiles. No hydrocarbons are
expected to have penetrated the dense "bedrock" encountered at 46
feet below grade at MW-7. TPH concentrations in two soil samples
collected at the bottom of Tank Pit 1, approximately 37 to 38 feet
below grade, range between 32 to 413 mg/kg. Approximately a 8 feet
thickness of soil (saprolite) remains in place in the tank pit
above the bedrock surface.
All groundwater quality results for this site are illustrated
in Table 1. Free product has not been detected. Laboratory
analyses of groundwater samples collected indicate that the
hydrocarbon present is primarily gasoline. Figure 7 illustrates
the horizontal extent of the dissolved BTEX plume in the
groundwater. This figure shows that the areal extent of
groundwater contamination is confined to the area around Tank Pit
1 and slightly downgradient of BMW-1 and MW-7. No dissolved
hydrocarbons were detected above quantitation limits in samples
collected in the peripheral wells (MW-3, MW-4, MW-5 and MW-6). The
leading edge of the dissolved hydrocarbon plume, as typically
defined by the downgradient extent of MTBE and total volatile
organic aromatics (VOA), has not yet reached any downgradient
wells.
3-3

The vertical extent of groundwater contamination extends
beneath Tank Pit 1 to the "bedrock" interface, which was
encountered at 46 feet below grade. We believe that the
groundwater contamination does not penetrate the dense bedrock, as
evidenced by the below quantitation limits of dissolved gasoline
and diesel constituents detected in groundwater sampled from
downgradient bedrock well MW-8, and due to lack of an apparent
vertical groundwater gradient and competence of the uppermost 2
feet of bedrock.
At present, groundwater quality results indicate elevated
dissolved gasoline constituents in BMW-1 and MW-7 only, with
greatest concentrations at BMW-1. Dissolved hydrocarbon components
detected in the groundwater between April 23 and July 29, 1990 were
HTEX, MTBE, chlorobenzene, dichlorobenzenes, 1,2-Dichloroethane,
Dibromochloromethane, and bis(2-Ethylhexyl)phthalate. All diesel
components, with exception to bis(2-Ethylhexyl)phthalate were
either below quantitation limits(BQL) or not detectable (NO). The
lateral dimensions of the total VOA plume in the shallow aquifer
are estimated at 180 feet long by 150 feet wide.
3.3 HYDRAULIC CONTROL
The remediation objectives for the shallow aquifer can be
achieved with the implementation of a pump and treat system. in
order to maximize the pumping rate from the area of greatest
dissolved hydrocarbons, the proposed pump and treat system
incorporates a recovery trench, two downgradient recovery wells
and an infiltration gallery. Figure 8 illustrates the layout of
the water treatment system superimposed on the base map.
Contaminated groundwater will be pumped out of the recovery trench
sump, (RT-1) and two downgradient recovery wells (RW-2 and RW-3)
for treatment by an air stripping tower. The treated effluent will
be discharged back into the aquifer through an infiltration gallery
located upgradient of Tank Pit 1. The infiltration of the treated
groundwater will add recharge to the aquifer necessary to maximize
pumping rates and possibly avoid dewatering of the recovery wells
3-4

and trench. The capture of the dissolved hydrocarbon plume within
the aquifer will be induced by the hydraulic gradients produced by
the recovery trench, the downgradient recovery wells and the
infiltration gallery. In order to enhance the capture of the
greatest dissolved hydrocarbons, the recovery trench will be
located inside Tank Pit 1. The recovery trench will be slightly
longer than the infiltration gallery to enhance the interception
of groundwater flowing from the gallery into the trench.
A finite difference model (U.S.G.S. MODFLOW 1984) was
developed to illustrate the impact of the planned remediation on
the groundwater regime and estimate the capture zone. Figure 9
presents the model predicted steady state water table surface with
the trench, the two downgradient recovery wells and infiltration
gallery in operation. Supporting information for the model is
included in Appendix I.
The flow rate necessary to achieve an adequate capture zone
within the shallow aquifer can be calculated by using the following
equation presented by Keely and Tsang (1983):
Q = 27rrhnV
where
Q = pumping rate (ft3/day)
r = downgradient length of the capture zone (ft);
estimated to be adequate at 100 ft.
h = effective saturated, thickness of the aquifer zone
yielding water to the recovery well (ft); estimated
at 16 ft.
n = estimated effective porosity (dimensionless);
estimated at 0.35
v = actual groundwater flow velocity (ft/day);
estimated for Site Assessment at 0.03 ft/day.
Therefore, the pumping rate required to achieve a stagnation
distance of approximately 100 feet per recovery well or trench is
0.5 gpm. This estimate is considered a maximum under ideal
subsurface conditions. However, a distance of less than 50 feet
is a more realistic estimation due to interference from multiple
pumping wells and our experience with pumping at similar sites.
3-5

Capture zone and drawdown calculations are provided in Appendix II.
A well head protection model (US EPA WHPA) was also run to
evaluate downgradient capture zones of the three recovery sources
(Appendix II). A capture zone of approximately 50 feet per
recovery source was determined from the model.
3.4 PUMPING RATES
The maximum available pumping rate for the unconfined aquifer
on -site was estimated from the Darcy equation:
Q = KIA/n
where
Q = flow fron well (volume/time)
K = hydraulic conductivity of aquifer (0.8 ft/day)
I = hydraulic gradient (1.25 x 10-2ft/ft)
A = Area of contaminated aquifer, measured in 'Site
Assessment at 27,000 ft'.
n = estimated effective porosity (0.35)
Therefore, solving the equation yields a maximum flow rate of
4 gpm from the aquifer.
The flow rates at the recovery trench (RT-1) and the two
recovery wells (RW-2 and RW-3) were estimated from the finite
difference model and the two previous calculations. it is
estimated that the pumping rate at each recovery well and trench
will be set at between 0.5 to 1 gpm to maximize groundwater pumping
rates and capture zones, without dewatering the wells or trench.
The total amount of water that will be generated for treatment by
the proposed groundwater recovery system is estimated to range from
2160 to 4320 gallons per day. It is estimated that it will take
between 2 to 4 years to turn over 3 to 5 site volumes (5 x 105 to
1 x 106 gallons) of contaminated groundwater. This amount is
estimated to be the minimum to achieve site clean-up.
The expected drawdown(s) for the recovery wells and trench
can be calculated using Jacobs equation (Drisco11,1985):
3-6

where
= 264 0 log 0.3 Tt
T r S
s = drawdown (ft)
Q = pumping rate (gpm); estimated at 0.5 to 1 gpm
T = transmissivity (gpd/ft); estimated at 96 gpd/ft.
t = time of pumping (days); estimated at 30 days
r = radius of the pumping well (ft); designated at 0.25
S = storage coefficient of an unconfined aquifer;
estimated at 0.1
then the drawdown at 0.5 gpm is 7.1 feet.
A groundwater program (Well and Pit, 1985) was used also to
evaluate the drawdown conditions of the recovery wells and trench
at 1 gpm. The drawdown after 30 days of pumping at 1 gpm was 10.1
feet. Appendix VIII contains the results of this program.
3.5 RECOVERY WELL AND TRENCH SPECIFICATIONS
This section describes in detail the rational, design and
function of the recovery system. The recovery well design, spacing
of recovery wells, and system efficiency (ie. pumping rates and
drawdowns) are based upon Westinghouse review of information
obtained from the Site Assessment, the finite difference model and
the Well and Pit program.
3.5.1 Recovery Well and Trench Location
The location and number of recovery wells were chosen in
consideration of the plume map (Figure 7), known aquifer properties
and estimations of the capture zones for pumping rates and pump
capacities. Because of the areal extent of the plume (180 feet
long by 150 feet wide), and the anticipated maximum capture zone
of 50 feet per recovery well or trench, two downgradient recovery
wells and one recovery trench will adequately capture the leading
edge of the plume while obtaining maxi um withdrawal of dissolved
hydrocarbons. An arrangement of multiple pumping wells will also
shorten flow paths for dissolved hydrocarbons to travel before
capture by one of the other recovery wells, thereby reducing the
overall time for groundwater restoration.
3 - 7

3.5.2 Recovery Well and Trench Design
The proposed groundwater recovery system will utilize recovery
wells (RW-2 and RW-3) and recovery trench (RT-1). Well
construction permit applications (Form GW-22B) will be submitted
to the NCDEHNR prior to installation. In order to effectively
capture the zone of dissolved hydrocarbons, the recovery wells will
be installed to the top of bedrock (46 feet below ground surface)
and screened with 0.010-inch slot from a depth of 27 to 46 feet
below ground surface. The two recovery wells will be 6 inches in
diameter.. The screened interval of the recovery wells will be
backfilled with a fine to medium grained sandpack to approximately
2 feet above the top of screen and overlain with a 2 to 3 feet
thick bentonite layer. A cement/bentonite slurry will be placed
above the bentonite seal. Recovery well construction is
illustrated in Figure 10.
A recovery well vault will be installed during system
installation. The doors of the vaults are capable of handling a
10,000 pound single axial wheel load and are elevated slightly
above grade to deter stormwater runoff infiltrating the vault
confine. The floor of the vault is covered with gravel to allow
any runoff to infiltrate rapidly thus avoiding flooding. Figure
11 illustrates a typical recovery well vault. Figure 12
illustrates valving connections inside the vault.
The conceptual design of the recovery trench is presented in
Figure 8. The trench bottom will be at 46 feet below grade inside
Tank Pit 1. The trench will be approximately 5 feet wide by 40
feet long. The trench will be backfilled with #57 stone to 35 feet
below grade and covered with clean soil to approximately 3 feet
above the water table in the tank pit.
A sump will be installed to collect the inflow into the
trench. Within the sump, a 10 foot long by 6 inch diameter,
slotted (0.010 inch) PVC screen and 10 foot casing will be
installed. A vault will also be installed for the recovery trench
3-8

well. Water level measurements will be accessible from the
recovery trench sump pipe.
3.5.3 Pump Design
The pumps used in the recovery wells RT-1, RW-2 and RW-3 will
be pneumatic total fluids submersible pumps (Figures 13 and 14)
manufactured by Westinghouse Groundwater Recovery, Inc- The
operating of these pumps will be controlled by a pneumatic control
system located in each recovery well vault and activated by a 5
horsepower air compressor located in the stockade (Figure 15). The
capacity of each pump is 1 to 9 gallons per minute. The pump will
be constructed of stainless steel and teflon. The combination of
stainless steel and teflon reduces friction and therefore promotes
longer life for the groundwater remediation system.
3.6 GROUNDWATER TREATMENT PROCESS,
A process and instrumentation diagram for the water treatment
system is shown in Figure 16. Groundwater produced by the proposed
recovery system will be pumped through 2-inch PVC lines into a 275-
gallon surge tank. A totalizing flowmeter (Figure 17) will be
installed on the influent manifold before the surge tank. Water
is then pulled from the surge tank by a 1 hp centrifugal transfer
pump (Figure 18) and sent to the top of the air stripping tower.
The transfer pump will operate at a flow of 10 gpm. Water
will inturn be discharged from the base of the air stripping tower
at a rate equal to that of the surge tank influent (estimated
average, 1.5 gpm) with the remainder (estimated 8.5 gpm)
recirculated from the tower back into the surge tank, as
illustrated in Figure 16. With this mode of operation, the
transfer pump and stripping tower blower will operate continuously.
A continuous, uniform flow of water through the stripping tower
will help maintain high volatile contaminant removal efficiency.
If iron fouling of the tower becomes a problem, the recirculation
rate will be reduced by lowering the flow rate from the transfer
pump to a minimum 5 gpm.
3 - 9

Transfer pump specifications are included with Figure 18.
The transfer pump can produce a total head of 75 feet. System head
loss calculations (Appendix III) reveal that the total head loss
for the air stripping tower is approximately 35 feet. Therefore,
the transfer pump will provide adequate head to carry the influent
water to the top of the tower.
As the influent enters the air stripper, it encounters an
atomizing spray nozzle. The nozzle has a relatively large internal
passage and a full cone, 1209 spray angle. The influent is then
dispersed evenly across the cross section of the air stripper to
reduce channeling. The air stripper will be mounted on a 6' by 8'
epoxy coated steel skid, on top of a 2 foot thick concrete
platform. The air stripper (Model ST012) shall be 12 inches in
diameter and 25 feet tall (Figures 19 and 20). A mist eliminator
is built into the air stripper acting as a restriction for fine
vapors and a trap for condensation. The air stripper will also be
equipped with a site tube to check for presence of chemical or
biofouling. Appendix IV contains all air stripping design
calculations. Air stripper packing shall be 1 inch diameter Jaeger
Tri-pace-high performance column packing. The Tri-packT" offers
low pressure drop, geometric symmetry, even gas and liquid
distribution, and high active (wet and exposed) surface area. The
counter -current air flow shall be provided by a 1/2 horsepower
American Fan, AF-9 (Figure 21). The nominal air flow rate shall
be 110 cfm with an air to water ratio of 150. The air stripping
tower with blower, air compressor, surge tank and transfer pump
will be contained within a fence (Figure 22).
Based on a worst case combined influent concentration of 9300
ug/L benzene, 29,000 ug/L toluene, 2300 ug/L ethyl benzene, and
13,000 ug/L total xylenes (reference Well BMW-1, 4/23/90), an
estimated maximum BTEX effluent concentration discharged to the
infiltration gallery is expected to be less than 30 ug/L BTEX. Air
stripper design calculations for each contaminant identified during
the Site Assessment are included in Appendix IV. The expected BTEX
3-10

concentration for each well/trench influent and the combined system
influent were estimated using a weighted average calculation
(Appendix V). The esti ated benzene and BTEX concentrations to be
air stripped are 2591 ug/L and 15,143 ug/L, respectively.
Therefore, using the contaminant removal efficiencies provided by
the 1988 Airstrip Ver. 1.2 program, the estimated benzene and BTEX
concentrations in the effluent should be less than 1 ug/L and 10
ug/L, respectively.
Because of the anticipated system efficiency and the
concentrations of constituents expected to enter the air stripping
tower, a North Carolina air emissions permit will not be required.
The total hydrocarbon (BTEX) emissions from the air stripping tower
are estimated to be approximately 0.55 lb./day. Air impact data
calculations are also provided in Appendix VI. System efficiencies
of greater than 99.93% for each of the dissolved contaminants
(worse case scenario) were calculated from the air stripper design
calculations (Appendix IV). Greater effeciencies are expected due
to recirculation of groundwater through air stripper and surge
tank.
3.6.1 Safety Features
To prevent overfilling of the surge tank, a mercury level
switch (LS01) will be installed. A level switch (LS02) will be
installed in the infiltration gallery to prevent it from
overfilling. Either switch will deactivate the groundwater
recovery system should water levels rise to unacceptable levels.
If there is blockage of the infiltration gallery, the air stripping
tower will be equipped with a level sensor (LS03) designed to shut
down the system and prevent overfilling of the air stripping tower.
Switches ES01 and ES02 stop the air compressor and the water
transfer pump, respectively, in the event that the air stripping
tower blower fails to operate. Electrical equipment within the
fenced area (i.e., the air stripper blower, water transfer pump and
air compressor) will be installed with explosion proof connections.

All Westinghouse groundwater recovery personnel involved with
system installation will comply with all regulations and directives
contained in OSHA 29, CFR Chapter XVII, Section 1910.120, covering
hazardous waste operations.
3.6.2 Water Sampling
Sampling ports (SPO1 through SPO5) will be installed to permit
retrieval of water samples at intermediate points in the treatment
process. These sampling ports (petcocks) will be located in each
of vault effluent line, the combined influent line before the surge
tank, and on the effluent line immediately after the air stripping
tower, as shown in Figure 16. Analysis of selected water samples
will be used to satisfy reporting requirements to the NCDEHNR as
specified in section 4.2 and to assess system operation.
3.7 EFFLUENT DISCHARGE
Effluent from the water treatment system will be gravity fed
into the infiltration gallery. The rate of infiltration was
estimated from data presented in the Iredell County Soil Survey and
from the bail tests previously discussed in section 3.1 and the
Site Assessment Report. A groundwater recharge program, Well &
Pit, Version 2, 1985 was used to simulate the expected mounding of
the water table under a recharge rate of 0.5 ft/day. The results
of the mounding analysis indicate that under a recharge of 3 gpm
over 360 days, the center of the mound will be approximately 16
feet below ground surface (Appendix VIII). The infiltration
gallery detail is presented in Figure 23.
The dimensions of the infiltration gallery are estimated to
be adequate at 1225 square feet (35 feet wide by 35 feet long).
The pit will be backfilled to a depth of 5 feet with #57 stone.
A subsurface pipe will conduct water from the treatment system to
a 4-inch perforated PVC pipe to disperse water into the stone
backfill. Monitor well MW-3 will be used to monitor the water
table near the infiltration gallery. The completed "Non -Discharge"
Permit Application is included in Appendix IX.
3-12

4 MONIT©RING AND MAIN'TEI CANCE
The monitoring and maintenance program will consist of both
periodic system optimization, and evaluation of groundwater quality
in the monitor wells, influent(s) and effluent.
4.1 SYSTEM MONITORING
The first week of system operation will include monitoring
and adjustment of all systems. The recovery pumps will be adjusted
until the desired hydraulic control of the aquifer is achieved.
Drawdowns will be measured periodically and compared with the
predicted drawdowns. Adjustments to the pumping rates will be made
if drawdown is excessive. Hydraulic head data will be contoured
quarterly and will be compared with the predicted capture zones.
System adjustments will be made if the pumping rates prove to be
insufficient to capture the dissolved hydrocarbons. The air
stripper will be monitored for operation and performance. Fittings
and connections will be checked for leaks. The spray zone and air
flow in the stripping tower will be adjusted to ensure that the
volatile hydrocarbons are removed. All fail safe equipment will
be checked periodically to ensure proper working order. The
monitoring and maintenance schedule are summarized in Table 4-1.
4.2 GROUNDWATER, INFLUENT AND EFFLUENT MONITORING
Groundwater samples will be collected periodically from
monitor wells,, influent(s) and effluent for analysis of purgeable
aromatics including in accordance with EPA Method 602 or for
constituents from the NCDEHNR list for sites containing Class I
petroleum hydrocarbons. The proposed sampling frequency schedule
for the site is illustrated in Table 4-2. Adjustments will be made
if removal rates are not acceptable.
Quarterly and annual progress reports will be submitted to the
MCDEHNR. These reports will provide information on system
efficiency, dissolved plume configuration, hydraulic head data,

Westinghouse Groundwater Recovery
in a sense, when Westinghouse
Groundwater Recovery has successfully
brought contaminated groundwater to the
surface. the job is just beginning. Now
WGR Air Stripping Towers are used to
cost-effectively and efficiently remove
hydrocarbons and other volatile
contaminants from recovered groundwater.
Three standard sizes are available,
ranging in diameter from 12 to 24 inches
and in height up to 30 feet, to cover
restoration projects for most shallow
aquifers. Other sizes can be specially
manufactured for a site's specific needs.
Depending on the quality of the
groundwater, the stripping towers can
reduce contaminant concentration from
parts per million to parts per billion,
bringing the water to most acceptable
standards, If some local or state
requirements are more stringent, activated
carbon filters may be used to "polish" the
water.
Contaminated water is pumped at the
designed flow rate to the top of the tower
where it is spread over packing material.
This material breaks up" the water into
small droplets, thus increasing the water's
surface area. An air fan blower then
forces a counter current air stream up
from the bottom of the tower. Mass
transfer occurs at the packing/water
interface and volatile contaminants are
stripped away.
Counter airstream blower.
Based on design flow rates and
anticipated groundwater quality, WGR's
engineers estimate the quality of the air
vented from a stripping tower and
determine necessary air pollution control
measures. Several control systems are
available.
Contaminants effectively removed by
WGR stripping towers are hydrocarbons
such as benzene, toluene and xylene and
chlorinated solvents such as
trichloroethane, trichboroethylene and
methylene chloride.
WGR Air Strippers are designed with
adjustable air -to -water ratios allowing
them to maintain optimal efficiency of
contaminant removal. The strippers are
constructed of corrosion resistant stainless
steel or polyvinylchloride and are
equipped with sensors to automatically
shut down towers in the event of airflow
loss. All WGR stripping towers are
available with or without explosion proof
components depending on site specific
needs.

GROUND -WATER FLOW MODEL
INTRODUCTION
The U.S.G.S. MODFLOW ground -water flow model by McDonald and
Uarbaugh (1984) was used to simulate the proposed remediation
system at the James Farm site. The objective of this simulation
was to evaluate the effectiveness of the proposed system in
remediating the ground water contaminated by release of petroleum
products.
The simulated remediation system consists of two ground -water
recovery wells.; an interceptor trench; and an infiltration gallery..
The concept of this system is that ground water will be pumped from
the trench, located in the contaminant source area, to recover the
most highly impacted ground water and depress the water table to
reduce the contaminant plume migration rate. The recovery wells,
located downgradient of the trench on a line perpendicular to the
flow direction, are to be pumped to recover impacted ground water
beyond the influence of the: trench, thus hydraulically isolating
the contaminant plume from the regional flow system. Ground water
pumped from the trench and recovery wells will be piped to a
treatment system where the concentration of contaminants will be
reduced to a predetermined, acceptable level. The treated water
will then be transferred to the infiltration gallery, upgradient of
the trench and contaminant plume, where it is re -introduced to the
flow system. This will cause a ground -water mound that locally
steepens the hydraulic gradient and increases the flow velocity of
the contaminant plume towards the recovery points. The locations
of these system components are shown on Figure 9.

The modeling activity consisted of three main tasks. These
tasks, and the basic purpose of each are:
Task 1. Model Definition: Data input to the computer
program, establishing model boundaries, and
defining the hydrogeologic parameters for the model
on the basis of field measurements and assumed
conditions.
Task 2. Model calibration: Calibrate the model under
steady-state conditions by refining the
hydrogeologic parameters defined during Task. 1
until the model replicates the observed site flow
conditions.
Task 3. Simulation of the Remediation System: Evaluate the
effect of the proposed remediation system on the
flow system under transient conditions.
The following are detailed descriptions of the modeling
efforts performed for each task, and an explanation of some basic
assumptions made to produce the model.
METHODS
TaskDefinition
A 500 feet by 500 feet area centered around tank pit No. 1 was
modeled. This model size was established to incorporate all areas
effected by the proposed remediation system and to eliminate or
minimize effects at the model boundaries produced by the simulated
stresses to the flow system. The model area was divided into a
grid of 25-foot by 25-foot cells, except near the model corners
where the cells were defined as 25-foot by 50-foot in the x and y
coordinate directions respectively.
2

The grid area was oriented in accordance with the flow system
with the left and right edges parallel to the water table elevation
contours, and the top and bottom edges parallel to the ground -water
flow lines. Cells on the perimeter of the model area were defined
as having constant heads. That is, the water table elevation was
not allowed to fluctuate in these cells. Constant head cells on
the top and bottom of the model. (along the flow direction) are used
to evaluate the adequacy of the model size by observing flow to or
from the cells as a result of flow system stresses applied during
the simulations. These cells would be essentially passive in that
no flow should be occurring to or from these cells. Constant head
cells on the right and left model boundaries (upgradient and.
downgradient, respectively) provide for ground -water through flow
through the model area. The ground -water flux in the cells are
measured and compared to flux rates estimated from analytical
techniques. The cells in the interior of the model are defined as
active. Active cells allow the potentiometric elevation of the
simulated flow system to fluctuate in response to the simulated
stresses.
The model of the flow system at the site was defined by data
input to the computer program. The flow system was defined as a
single layer, unconfined system which is everywhere homogeneous and
isotropic. The hydraulic conductivity for the flow system was
defined as 0.8 feet per day, based on slug tests at the onsite
monitoring wells. The existing water table surface elevations were
input to the starting potentiometric head array in the model on the
basis of the measured elevations in the onsite monitoring wells on
August 5, 1990. Elevation values were projected laterally in order
to fill the model grid and maintain the observed hydraulic gradient
of 0.01 feet per foot. Ground -water recharge was defined in the
model as 15 percent of the average annual precipitation rate of 42

inches per year (Heath, 1980). The saturated thickness of the flow
system was initially defined as 50 feet to include the
saprolite/residuum and a portion of the fractured bedrock. This
saturated thickness was subsequently increased to 137 feet in order
to accommodate simulated recharge to the flow system.
Task 2: Model Calibration
The model was calibrated under steady-state conditions to
duplicate, as closely as possible, the observed water table surface
at the site, and calculated ground -water flux through the
hydrogeologic system. Transmissitivity in the model flow system
was adjusted to accommodate the ground -water recharge by changing
the saturated thickness. A reasonable balance was achieved with an
average saturated thickness of about 137 feet. Ground -water flux
through the model area was calculated by applying Darcy's equation;
Q=KIA, to the flow system based on the input parameters that
produced a close duplication of the observed water table surface at
the site. Computer output of flow rates at the upgradient and
downgradient constant head cells were compared with the calculated
flux through the system. Adjustments were made to the model
parameters until the computed flux was within 10 percent of the
calculated values.
After the model was calibrated under steady-state conditions,
the model was run under transient conditions for a simulation.
period of one year. This allowed the model sufficient time to
reach a steady-state condition. A storage coefficient of 0.1 was
used for the flow system in the transient case. The water table
elevation values (heads) calculated by the model in the transient
simulation were used as starting heads for simulation of the
remediation system.
4

Task 3: Sirnulation of the Remediation System
As stated previously, the proposed remediation system consists
of two ground -water recovery wells; an interceptor trench; and an
infiltration gallery. The locations of these system components are
shown on Figure
The interceptor trench was simulated with the drain package in
MODFLOW. A drain was established in two model cells in the
southwest side of tank pit No. 1 for a combined simulated length of
50 feet. In actuality, the trench will be somewhat shorter, so the
pumping rate applied to the simulated drains is based on a 35-foot
long trench. The simulated drain has a width of five feet.
Although available drawdown in the proposed trench is
approximately 16 feet (i.e., saturated thickness of residuum/
saprolite), a drawdown of ten feet was simulated to account for
head losses in the trench. The drawdown was simulated by setting
the elevation of the drain ten feet below the static potentiometric
head in the model cell. In the absence of field data, expected
flow to the trench was estimated at approximately 0.9 gallons per
minute (gpm) from Darcy's equation for a trench 35 feet long, five
feet wide, and with an average saturated thickness of six feet.
Drain conductance, a parameter defining potential flow to a drain,
was then calculated according to the method described by McDonald
and Harbaugh (1984) to define a 1.0 gpm flow rate to the drain for
input to the program.
Two recovery wells were simulated at locations downgradient of
the trench near the projected end of the contaminant plume (Figure
1). The Theis equation was used to predict the potential yield of
the wells after steady-state radial flow was reached with ten feet
of drawdown and sixteen feet of non -pumping saturated thickness.
5

From calculations at various time steps, an estimated yield of 0.75
gpm could be sustained from each well, for a combined well yield of
1.5 gpm. Capture zones were calculated for the wells according to
the method described by Javandel and Tsang (1986). The stagnation
point was estimated to be approximately 47 feet downgradient of the
wells. In combination, the optimum position of two pumping wells
was estimated to be approximately 95 feet apart perpendicular to
the ground -water flow direction. The wells were simulated at 75
feet apart to account for well inefficiencies.
The final component of the simulated ground -water remediation
system was the infiltration gallery, located upgradient of the
interceptor trench. Infiltration was simulated by increasing
recharge to one of the 25 X 25 foot cells equal to the combined
discharge rates of the trench and recovery wells, or 2.5 gpm.
RESULTS
MODFLOW was run to simulate the effects of the remediation
system on the flow system for a one year period. The resulting
potentiometric heads were formatted and transferred to a mapping
program (SURFER) which produced a contour map of the final heads.
This map was superimposed on the site map, and is presented as
Figure 1. The capture zone, flow pattern, and ground -water
stagnation points produced by the drains and pumping wells were
drawn on the figure to illustrate the flow system components during
operation of the remediation system. The map indicates that the
projected area of impacted ground water, and water from the
infiltration gallery will be captured by the trench and recovery
wells. The interceptor trench also lowers the hydraulic gradient
upgradient of the wells which in turn should increase the distance
of the calculated stagnation point downgradient of the wells.
6

SENSITIVITY ANALYSIS
A sensitivity analysis was performed to evaluate the
confidence level of the model simulated results given reasonable
variations to the input parameters. The sensitivity analysis can
be used to evaluate different parameter values on the overall
response and effectiveness of the remediation system. It should be
noted the flux through the flow system and remediation systems are
very small. Therefore, small charges in the flux can be a large
percentage of the total flux.
Isotropy and homogeneity of the saturated zone is unlikely.
These assumptions are made to simplify the modeling effort in the
absence of extensive field data. Anisotropy and inhomogeneity of
the saturated zone may produce a capture zone skewed from the
predicted direction. Stressing the flow system could therefore
produce an asymmetrical capture zone, and/or one of lessor or
greater extent than predicted by the model.
Flow rates of the recovery wells and trench will also effect
the capture zone. Several model runs, at flow rates of 0.5 gpm,
1.0 gpm, and combinations of these rates from the two wells and
trench, were made to evaluate the recovery system performance in
the event the actual achievable recovery rates are more or less
than expected. The recharge rate at the infiltration gallery was
altered at each run to correspond with the combined discharge of
the recovery system. As expected, the size of the capture zone
decreased with the lower pumping rates and increased with the
higher rates. At a combined flow rate of 1.5 gpm (0.5 gpm from
each extraction point), approximately 95 percent of the projected
extent of the contaminant plume is captured. Moving the recovery
wells about 25 feet further downgradient of the trench improved the
capture, of the plume area to 100 percent in the model. At a
7

combined rate of 3.0 gpm (1.0 gpm from each extraction point), the
capture zone increased in the model to include approximately 5 to
10 percent more area than the projected area of the plume.
If the hydraulic conductivity is lower or higher than
simulated, the recovery and infiltration rate will 'vary in a
directly proportional manner. However, the capture zone should not
significantly change.
The capture zone size will vary inversely to the recharge rate
and storage coefficient, whereas the recovery rate will vary
directly with the recharge rate and storage coefficient.

FLOW FROM WELLS ANO RECHARGE PITS
VERSION 2.0
(C) Copyrighted, 1985, Groundwater Program, CSU
IBM-PC Dos 2.1 USER'S MANUAL
Groundwater Program
Colorado State University
Daniel K. Sunada, Professor in Charge
Introduction
Program FLOW FROM WELLS AND RECHARGE PITS allows you to predict the
response of a water table to discharge from wells or artificial recharge
of water from rectangular basins in a homogeneous aquifer of infinite
aerial extent, in a homogeneous stream aquifer system or in an aquifer
having a vertical impermeable boundary. The model calculates discharge
(recharge) to the stream in a stream aquifer system at times specified by
the user. Iiilizat:on of graphics allow visual evaluation of r.lsults
which can be saved to and recalled from disk storage. In this manner
comparisons can be easily made between different flow situations. The
program is interactive and is designed to be self-explanatory. This
manual explains the various options available. Make a backup copy of the
floppy disk using the DOS copy command. Please do not give this program
to others to use.
System Requirements
You will need an IBM-PC, XT, AT, or IBM compatible computer with a
minimum of 128K of storage, one disk drive, and monitor (graphics monitor
is necessary to obtain graphical output). Printout of numerical results
is available in the program.

Starting the Program
Place the disk containing the artificial recharge program in the
default drive. For the first time use of this program run CONFIG to
configure the program to your system. You will be able to run either the
COMPAQ version or the IBM version with, or without the graphics monitor.
Follow the prompts in the program. rf you make a mistake or wish to
change the configuration, just run CONFIG again. Thereafter, type
WELL&PIT and the program will begin execution. You can also create an
AUTOEXEC.BAT file to do this.
Program Options Menu
The first menu provided, gives you the option of selection flow to a
well or flow from a rectangular recharge area. The second menu provided,
gives you a choice of program options. At this point you decide whether
you want to simulate recharge in an aquifer of infinite aerial extent (the
NO STREAM option), a stream -aquifer system (the STREAM IN VICINITY
option), or an impermeable boundary option. If one of these options is
selected, the present value of the input data will be displayed on the
screen.
The READ FILES option allows you to read files that were previously
stored on disk. This provides a means of loading previously used and
calculated results into the computer. With this capability you can easily
compare results of many analyses.
If you choose the READ FILES option you will be asked for the file
name. The program allows you to view the catalog to help you recall the
names of files. If you want to escape from this option, type STOP. After
reading a file the program goes to the output options section described
later.

ECHARGE RATE (ft/day): The recharge rate is the volume of water
recharged per surface area of the recharge basin per unit time. A
constant recharge rate is used throughout the recharge period, mound
heights, however, May be calculated befolid the reCharge periods.

OISCHARGE RATE (gpm): A constant discharge rate isused thrOghout the
flow Period. This option iS available only for the analysis of a well.
AQUIFER PARAMETERS: TRANSMISSIVITY (square feet/day) and SPECIFIC YIELD
(dimensionless) are constants for the homogeneous aquifer.
TIME PERIOD: Calculations are performed at discrete times. The BEGINNING
TIME (days) must be greater than 0 and is the first time that the
calculations are made. The TIME INCREMENT (days) gives the time interval
between calculations. The FINAL TIME (days) gives the last time that
calculations are to be made. For example, if the beginning time is 10
days, the time increment is 5 days and the final time is 20 days,
calculations will be made at 10, 15, and 20 days. The final and in 'al
times must be intege1tjie af the time increment.
END OF RECHARGE PERIOD: The end of the recharge or discharge period
(days) is the time when artificial recharge or well discharge is
erminated. The program will continue to calculate molind profiles until

Distance: You must specify the points at which the recharge mount height
is to be calculated. The BEGINNING DISTANCE (ft) is always set to 0 which
is directly under the center of the basin or at the well. The DISTANCE
INCREMENT (ft) gives the distance between points of mount height
,calculations.
FINAL DISTANCE (ft): This is the last point at which the mound height is
to be calculated. For example, if the distance increment is 50 feet and
the final distance is 300 feet, the mound height will be calculated at 0,
50, 100, 150, 200, 250, and 300 feet.
DEPTH TO WATER (ft): The depth to water is the distance from the ground
surface to the water table in feet. Various depth to water may be
selected to change the scale of mound heights. The time required for
water to travel from ground surface to the water table is not taken into
account.
SATURATED THICKNESS (ft): This is the distance from the bottom of the
aquifer to the water table.
BASIN GEOMETRY: A rectangular basin is used, so enter the LENGTH and
WIDTH in feet. Using a square basin to approximate a circular basin of
equal area provides an excellent means of calculating the mound profile
underneath a circular basin. Rectangular basins can often provide very
good approximations of basins of irregular geometry. In a stream aquifer_
system the width, is always along the axis of the stream.

ANGLE (degrees): This specifies the angle measured from a line drawn
perpendicular from the center of the well or recharge basin to the stream
or impermeable boundary. The mound profile is calculated along this line.
_DISTANCE TO STREAM (ft) or DISTANCE TO tMPERMEABLE BOUNDARY (ft) : The
distance to the boundary is measured from the center of recharge basin
(well) to the stream. The basin is always set up so that the width is
parallel to the stream.
CALCULATE MOUND PROFILE and CALCULATE DISCHARGE TO STREAM: These options
arise if you are modeling a stream aquifer system. You can either have the
program calculate the mound profile or calculate the discharge to the
stream or both.
The variables are changed by typing in the number corresponding to
the variable. For example, if you want to change the transmissivity,
enter 2. The old value of the variable will appear on the screen and you
will be asked to input the updated vathe. After the updating is completed
you will be returned to the main data display. When you press the -
<RETURN> key the pro ram begins calculating with the present parameters.
Calculations:
As points on the mound are calculated they are plotted on the screen.
When the calculations are finished, you will be asked to type <RETURN> to
continue. All results are kept in memory and the output options menu
appears.

Output Options:
This section of the program allows you to study results. You arrive
at this section from either the read files section or after completing
calculations. If you have read several files into memory, you will be
- asked to specify which file you wish to study.
DATA SPLAY: The current input data are displayed on the screen.
RESULTS DISPLAY: The values for mound height and/or discharge to the
stream are shown on the screen.
GRAPHICS DISPLAY: The graphics are recreated on the graphics screen if
you have one. You will be asked if you wish to save the graphics screen.
The saved screen can later be used to obtain a hard copy of the graph if
you have the graphics dump software available.
RESULTS PRINTOUT: Input data and results are printed out. A graphics
dump is not included in this program. The graphics can be saved to disk
and should be accessible by screen dump programs.
CREATE FILE: If you have just calculated mound profiles, you can store
data and results on the disk with this option. Just provide a file name
and the program will write all the information to the disk.
READ ANQTHER_F,ILE: If you have just read a file, this option allows you
to read more files. In this way you can quickly compare results from
separate analyses. Up to a maximum of ten files may be read into memory.

MULTIP E GRAP CS p SPLAY: Choose this option if you wish to compare
graphs of different files. After choosing this option another menu
appears with four options. PRINT OUT RESULTS allows numerical results of
different files to be compared on a hard copy. READ A FILE allows you to
read in additional files into memory. EXIT TO PREVIOUS MENU selection
takes you back to the preceding menu.
After selecting DISPLAY GRAPHICS a list of files which have been read
into memory are displayed. You are asked how many files you wish to
compare up to a maximum of three files. Next you are asked to type the
number of the file you wish to compare. You are asked if you wish to save
the graphics screen. The graphics screen is saved in a "Filename.PIC"
file which, can later be used to obtain a hard copy of the graph if you
have a program to dump graphics to your particular printer. The graphics
are then displayed on the graphics screen. You can display the results
from a well analysis to that of a recharge pit but the, graph will be
distorted because of the way the PC plots the data.
ANOTHER RUN: This allows you to move back to the original recharge
options. The most recent data will be kept in memory and shown in the
data display. This is one way to enter basic data without having to go
back and change data on every run. However, computed data and results
read in from files will be last.
The program will terminate.
Note: Roundoff and mathematical approximations may produce funny results.
