to wet conditions have prevented our attempts to finish the final three,, We hope to accomplish,
this tomorrow the l5tb of this month, however should advise your office that, we may require a,
formal extension to accomplish this work. We should still, bowever, be an line with the overall

MEMORANDUM ERA L ti
To: Carolyn McCaskill
Through: Bob Cheek oz
From. David Goodrich
Subject; J.E. Collins Residence
Groundwater l ernediation System
Rowan County
(Michael Allen. DE€'1 SERG Review Engineer)
The Groundwater Section has reviewed the subject permit application for the r t on of
a groundwater remediation system at the .1.13. Collins residence,
The facility is the site of an accidental ,gasoline release (set Figure I) from a 1,000-gallon
capacity underground storage tank on the Collins farm. The release was first detected in the eater
supply of a nearby (Collin) well (see Figure ) in 1989. The underground storage tare was,
removed in March of 1993 and the adjoining soils were found to contain high levels of benzene;
toluene, ethylben ene, and xylene (BTE . The site was investigated and a Comprehensive Site
Assessment was performed which provided the information needed to prepare a Corrective Action
Plan. The site information included as part of the Corrective Action Plan indicated that gasoline
from the release has affected the shallow twater table) aquifer and the deep (t'ractured bedrock
aquifer systems,
Contaminants associated with the gasoline spill have traveled more than eight hundred feet
to the southwest within the fractured bedrock aquifer system, as evidenced by the detection of
gasoline constituents in Collins Well . The proposed groundwater rernediation system will
utilize a former eater supply well (OW-1) to intercept and recover sornew ere between 720 and
!j 2880 gallons of ground eater per flay. The eater will be air -lifted from the well in carder to strip
Taff gasoline constituents, and this will constitute an initial treanuent by lowering the
concentration of contaminants in the recovered ground water. The water will be returned to the
subsurface through an in -situ vacuum vaporizing well (p)"f3-1), Dare to the fact that the;
rernedlat n; portion of the vaporizing well is hydraulically connected to the aquifer and that
1

there is no means of verifying that a desired level of cleanup has been achieved in the
recovered water prior its injection into the aquifer, the recovered ground water will have
to be treated to a 95 e vaporizingwell. The
water will have to be sampled prior to injection to verify that this level of cleanup has been
achieved.
The pumping records fr(-,,)m the two bedrock water supply wells (designated as Off'- I and
Collins Well #1) have indicated short-term yields of two gallons per minute and ninety gallons
per minute, respectively. Although the OW- I well is 160 feet deep and the Collins #I well is 260
feet deep, this difference in depth (by itself) cannot account for the wide disparity in yield.
Due to the anisotropic and heterogeneous nature of fi-actured bedrock, aquifers, there are two
problems typically encountered when attempting to estimate their hydraulic properties. The first
problem is that the well which is being tested for yield has a narrow diameter relative to the
width and length of the aquifer and the hydraulic properties of the fractures intersected may not
be representative (if the entire aquifer. These fractures may also not be "ty p ically" connected to
�
other fractures within the aquifer, The second problem is that the amount of hydraulic storage
and resistance (from friction) can vary tremendously with location and direction within each
fracture.
The respective yields and depths of the two water supply wells suggest horizontal hydraulic
conductivity values on the order of 0.0238 ft/day and 0.385 ftiday (0.000136 crn/sec) for the
fractured bedrock aquifer. Since the higher value of hydraulic conductivity I , probably represents
"better" hydraulic connections between the well and the bedrock fractures, this value may be
more representative of the aquifer's hydraulic properties. The horizontal hydraulic conductivity
of 0.0001 ctn'second assumed by the applicant is relatively close to this value.
The proposed remediation system for this site is an in -situ UVB (Vacuum Vaporizing Well)
system, an innovative technology originally developed in Gerniany. This system is designed to
remediate the shallow, unconsolidated aquifer by removing affected ground water from tile
aquifer through the lower screen section of a shallow vaporizing well which will be located near
thecenter of the contaminant plume, The affected ground water will be oxygenated and stripped
of VOC's without actually leaving the well, and then re -introduced into the aquifer by way, of
the upper well screen. This action will establish a horizontal and vertical circulation within the
shallow aquifer which will enhance the remediation process by flushing the aquifer.
Existing deep well OW-1 is reportedly located do gradient of the most concentrated portion
of the gasoline plume (see Figure 4.2 of the application package), and this well will be used to
intercept and recover deep (and shallow) ground water for treatment and re -introduction into the
shallow aquifer through the vaporization well. According to the regulations regarding re-
injection. the recovered ground water must meet a cleanup level of 95% before it is returned to
the subsurface.
The treatment system, as proposed in the application, will have to be amended to
include some form of purification which will remove 95% of the contamination from the
2

recovered groundwater before it is introduced into the vaporizing well, The effluent from this
purification system will have to be sampled to verity that this level has been achieved.
Due to the relative absence of hydraulic monitoring g points in the immediate vicinity of the
affected :area. the Groundwater Section is recommending, the installation of six shallow monitor
wells (MW- 1, MW-2, MW-3, MW-4, MW-5, and MW-tit between the Compliance Boundary and
the UVB injection well (see Figure 2).
The Groundwater Section has reviewed the subject perinit renewal application and recommends
reissuance of the permit with the following conditions:
I , The proposed system shall be amended to include treatment of the recovered ground
water, recovered by Well OW-1 before it is introduced into the UVB injection/treatment
well. The influent and effluent of the treatment system will be sampled by EPA methods
602 and 610 to verify that the required cleanup level of 95% has been achieved. The
influent and effluent from the treatment system shall be sampled for BTEX and mTBE
by EPA Method 602, and for naphthalene by EPA Method 610 immediately after the
system start-up, once every two (2) weeks for the first three (3) months, and monthly
thereafter. If the treatment system consistently fails to achieve the 95% cleanup standard,
additional treatment units or changes in operational methods may be required.
The results of the sampling and analysis shall be sent to the Groundwater Section. permits and
Compliance Unit, P.O. Box 29535 Raleigh. N.C, 27626-0535 within 30 days of sample

The following are responses to questions posed by, the Groundwater Section relative to the above
application, number. In addition, and based upon verbal communications, au additional response,
is included which was not included in the May 30, 1995 correspondence. That response is in
regard to injecting wastewater into an injection well. We have added an additional rernedial
component to our plan to address this concern, if required and necessary.
The following responses are in thesame order as that presented in the May 30, 1995
correspondence:
1). Please refer to F-rhibit 1.
2). The Collins site is located in as rural area which relies solely upon round-waterforpotable
supplies. Two wells are documented to be impacted ky BTEX and other volatile compounds, the
Collins well and the 2-inch well (OW-1) at the reacted propertv. This contamination is evidently

If flow in the UVB well is supplemented by injection or extraction from the surface, the
hydraulic head changes are altered according to Figures 8® and E8-2. These diagrams are
based on the restriction that no hydraulic head change occurs due to the injected or extracted
flo vv.
Injection of water into the UVB will result in hydraulic head increases at the upper and lower
screens as compared to the UVB with no injection. This is due to the higher head needed to
move water out through both screens.

Proposal for Groundwater Extraction and Treatment by Airlift Pumping
This amendment to the initial Corrective Action Plan (CAP) consists of extracting groundwater from the
abandoned water supply well OW-1 by airlift pumping, which will allow for simultaneous air spar in
as groundwater rises to the top of the well bead.
A determination of the airlift pump operating parameters requires an estimate of the expected drawdown.
At OW-1, the pumping rate, transmissivity, radius of influence, and well radius are I gpm, 20 W/day,
70 ft., and 12 in., respectively. The radius of influence is assumed to be the distance from OW-1 to the
UVB well where the water will be recharged. Using the parameters in the "equilibrium' or "Miem"
equation, the drawdown is estimated to be 10 ft.
The air lift pump requirements are based on certain characteristics of the well. At OW-1, the static water
level S, the estimated drawdown D, the pumping lift L. = (S + D), the discharge rate Q, the total depth
of the air line below ground surface A are 10 ft. bgs (below ground surface), 10 ft, bgs, I gpm, 30 ft bgs,
respectively. The percent submergence is calculated as 100(A - L)/A = 33%. The starting air pressure
is calculated as P = (A - S)/2.31 = 8.7 psi. The required volumetric flow rate can then be estimated
as follows:
C log[(A - L + 34)134]
For the given submergence, the constant C is 162. The required air flow rate V, can then be calculated
as 1, 1 W per gallon of water pumped, or 1.1 cfm. The reference for these calculations is the Handbook
of Ground Water 1 evelo2m ent by Roscoe Moss Company, 1990,

1.0 Ijai TRODUCTIONANDBACKGROUND
Geo�nvirontncntal is pleased to submit in this document the results of out screening of
retnedial alternatives for corrective action at the J.B. Collins Residence (Incident #
10047) located in the Town of Woodleaf, Rowan County, North Carolina. The
requirement for corrective action is based upon the, release of gasoline from a farni tank
located on the subject property, The tank was property registered with fees paid and has
been entered into the North Carolina Trust Fund (Non-Commericial) for the cost of
restoring groundwater quality. A Comphrehensive Site Assessment has been submitted
for the site in Match, 1094, defining the need for corrective action. The following
discussion describes the past history of the incident, and steps which have been taken in
an effort to define the extent of impact. The Corrective Action Plan (CAP) was prepared
by Geonvirontricntal, IEG Technologies, Inc, and Uke Norman Drilling, Inc.

1.3 HISTORY OF RELEASE
e, tallowin surnmaary is taa enfrom the Piedmont Environmental report datedJune 22, 1993
and also l"'raaaaa iratervieav s with Mr. Collins by GeoEnvironrr entaal The site wars originallyserved
lay two groundivatersupply wells. The Collins residence and migrate or ers housokg was
supplied ky as vvell behind the Collins residence (labeled Collins # 2 in this report). The small
house next to the Collins was servedby as Vie, aaraate well ( as small 2 " gel(, labeled OW-1 in this
report). Approximatelyfiveyears ago, the tvvo inch well became contaminated mated bygasoline. Ire
vas=ell was disconnected and as water line connected to the ollin's well. In 1992, an odor was
noticed in the waterfrom well #1 ( ollin "s ''ell). A packer was installed in the well at 200feet
in an attempt to Prevent surface contaminantsftoin entering the vvell. 7he odor continued. In
March, 1993, Mr. Collins removed the 1, , aall n UST, and Piedmont Environrraenta l was
contracted to test the open ca-vity scads. Those soils ivere ourad to contain high le ge& of BTEX
constituents. Later in March, the Collin's well was sampled and 58ppb of benzene was reported
by the anakytical liaborcatot)% This well was stopped being use as as potable water .source and ca
new well was drill ed feet east (ulrslope) of the ollin's well. This well, designaated aas Well'
later in this document, was tested and no BTEX a.arrrapou were detected

The site is located in the Charlotte Pelt of the Piedmont Province. The Geologic Map of North
Carolina (1985, 1 G shows the area. to be underlain keg units of inetaamor hac° inafic rocky.
According to the Piedmont Environmental, Inc. June 1 report, "...rocks encountered in well

borings and in the cavity excavation were examined in hand specimen. They consists largely of
coarse -grained high sodium plragioclrase feldspar and fe °rornaagnesiaa a minerals in approximately
a q aalproportions with minor visible al m '. Based upon examination tion of outcrops mar the
farm, the Piedmont report is supported in identification of the rock type as predominantly dioitew
The rock exhibits a strong lineation texture,
The Piedmont report also identifies as strong regia nal joint pattern in the sile vicinity, which i
vet evident in they drainage pattern of Fourth Creek Thepr doinar toir t, pattern trends
nor-theast1northwest, which is consistent to the fractaare pattern of the soaath rn Piedmont.
According to the Piedmont Environmental report.... ' a ture tsars analysis ann t be used to as
much to predict the direction ofcontaminant migration as to indicate the presence ofsuch
,fractures will greatly y enhance the migration of contaminants through rock ......these
micra fr'cactaares in the rock: create a high degree ofsecondary l r€asiq, in the rock-, which offersqffers ra
highly effective conduitfor the vertical and lateral migration of released contaminants....
The nature of the highlyfractured rock at the site, coupled with hydr w ract wring of the rock J
previous drilling activities, has likely contributed to contaminant migration tarry the t-ww o fa nner
drinking vvater wwrells. Purnping from these wells over the period of time involved has libel
captured the rhyme fr°°ont extensi ve down -gradien migratio a, Asurveyofftacturelineamentsis
shown on Figure 3. Tivo prominent joint'sets are distinguished the strongest trending NW, are
the second to the northeast. 7hefirstset is getter manifested in stream wraall , and can be
readily associated with strong off -sets in Fourth Creek and the '" adk n River. Ire second set is
better observed along stream va lleys, ridge slopes and ridge taps; and is consistent with the
regional structuraltrend of thCharlotte Belt in this location. Other, leas prominent sets trend
roughly in an east - west manner, and are less pronounced unless where intersecting with the
major sets, forming rough blocks of terrain. Most of"the major ridges in the area are associated
with these blocks.
3.0 EXPOSUREASSESSMENT
3A PHYSICAL AND CHEMICAL PROPERTIES OF CONTAM�
Contaminants identified on -sate include low boiling point volatile organic, compounds usually
associatedwith gasoline. 71te most toxic of these co pounds is generally held by the USEPA to
be benzene, which is a known human carcinogen. This chemical promotes Troth acute and
chromic toxilogical effects on humans. Acute effects included headaches and nausea. Chronic
effects include brae marrow cancer or damage. Other i s toxic compounds detected on -site
include toluene, xlenes and eta lhen ene. Those acute effects includefatigue, weakness and
confusion and Central NervousSystem () depression. Chronic ejects for these contpounds
are similar syarptorras only more severe. Catastrophic exposure to anof these compounds may
re.saalt in death. Various polynuclear aromatic hydrocarbons (PN 's) have also been detected
on -site These compounds typically comprise the higher boiling pointfraction of the petroleum
lkydrocarlron series. These compounds are known aninaaal carcinogins and some are suspected
human carcinogens-
3.2 PATHWAYS FOR HUMAN EXPOSURE
The primary pathwa fret° human exposure at this site is considered to be ingestion of
c ontaaminaated groundivater or inhalation of vapors. were is some potential ford contact exposure
frorn contaminated snit andfront contact with °ontantina ted water. There are several drinking
waterwells in the general site area which, have been inn actedfrorn gasoline contamination.
3.3 POTENTIAL E RECEPTOR

of 20ppm, based upon a categoiy A site. However, corwidering that a,static groundivater level in
thhs area is aabaave l6feet and that solid raga.k is prevalent below l6 feet, the aarraount ofsoil
excavatedfrom the cavity is the inaxiinum amount which would,be possible, andfurther
rerrr rliaation will rely apon a groundwater clean-up scenario. Its addition, based upon contact
of the r table with contaminated soi4 the SSE ruleis not 'strx t applicable to site,
Bard boring data is included in Attachment A, with laboratory reports in Attachment B.

The following discussion describes 1n more detail each of the 4- }lect t options, their
principal conceptual design e:omponerl safety features, m " to m e and operational
feasibility and a schedule for implementation of the individual components.
This section outlines In detail the recommended program for groundwater extraction and
treatment.
The design of this system is based to a large degree upon our collective experience nce in the
hydraulic characteristics of shallow groundwater in Piedmont soils. Yield from recovery
ells In tight Piedmont soils are generally on the- order less than .5 to 2 gallons per
mute for any one producing well. The low yield is due to low tram `ssi ity of
Piedmont soil, generally on the order of 10 to :20 square feet per day. Although these
soils can often reach hydraulic conductivity values for a givers monitoring well
approaching, time sec, the overall heterogenity of the zone to be pumped can often
result in a shallow aquifer hydraulic conductivity of 10"to 1 �e sec Pear this reason,
steady dy state radirts of influence can tale mouths to years in approaching a maximum
capture zone sufficient to significantly impact capture of they plume. Considering the size
of the. plume, and also the rapid recharge of the monitoring wells during development
d purging, e recommend that a pilot recovery system he installed consisting of a
recovery well _l at the location of Figure 7.1 A groundwater analyticat
model was used to simulate a pumping wellwith an aquifer s siity of 20 sftd , a
pumping rate f 5- I rrr, and a hydraulic gradient of .Gl 5. Porosity s sti aced at

zone of about 50 feet can be: established from e well in a period of about 1.80 day

7.1a1 RECOVERY WELL DESCRIPTION
E

The recovery system comprised of one recovery well and the treatment system and
disposal practice will be discussed below.
-7. 1.2 RECOVERY WELL LOCATION'
The location of the recovery well (Figure 7.1) was chosen based upon the site layout and
the need of having a well in the downgradient portion of the plume and also a well in
proximity to the higher concentration area of the plume. The well is positioned to control
plume migration as well as collect contaminated Neater for treatment and to also serve as
an indication of the feasibility of groundrater injection and/or infiltration. There also
currently exist a pumping well in this location which can serve as a recovery well. The
current well has already been abandoned as a functional potable watersupply,
7.1.3 RECOVERY WELL DESIGN
Initially we anticipate that the present OW-1 well can, serve as the recovery well, since
the well is already placed downgradient of the higher concentration area of the plume and
is already a ftmetional well.

7.3 SAFETY FEATURES
A nrain consideration in die selection of the proposed system is the relatively simple and
compact manner in which the systern can operate. This is especially significant
considering the proximity of the eff6cted areas to normal farm operations and exposure
pathways to working nel. The low concentrations, of contarninants expected in the
person
system effluents are not near to explosive levels, although the equipment that we chose
,7
M

will be explosion proof. The cl ctrical components and the lines to the recovery pump
will be installed by a licensed l trician. Level sense _ in the recovery- well will cot th
system off with the absence m i nt water to extract. All system otwill he
insulated to inhibit frecvjng
All conduits and manifolds r and not accessible to contact by farm
.
The system monitoringprogram will consist of sampling of pre-treatment, system
effluent and influent and also post -treatment di. ,h. c water. A -system of piezonieters
will also he installed at localities around the facility intersecting the growidwater table,
such that static water levels can be onitored as an indication of system rf'o r c .
This testing will" beaccomplished on a minimum monthly basis for the initial year of
operation. rind the first month of system start-up this monitoring will be conducted
bi-weekly. The effluent and fluent water will be, analyzedfor EPA Method
compounds. In addition, discharge water will be analyzed for 1, biological oxygen
demand „ chemical oxygen demand (COD) and total suspended solids d.
Additional testing of any permit parameters a: specified in the plants, is discharge permit
will also be nducted. GeoEnvironmental will forward the results of the system
monitoring to the on a calendar quarterly basis.

remedial alternatives for corrective action at the J.B. Collins Residence (Incident #
10047) located in the Town of dleaf, Rowan County, North Carolina. The
requirement, for corrective action is based upon rite release of gasoline front a fattil tank
located on the subject property. The tank was properly registered with fees paid and has
been entered into the North Carolina Trust and (Non - Commercial) fear the cost of
restoring groundwater quality. A Comphrebensive Site Assessment has been submitted
for the site in, March, 1994, defining the need for corrective action. The following
discussion describes the past history of the incident and steps which have been taken in
an effort to define the extent of impact. The Corrective Action Plan (CAP) was prepared
by GeoFnvironmental, IEG Technologies, Inc. and Lake Norman Drilling, Inc.
L I HISTORY OF PROBLEM
This Corrective Action Plan (CA P) is being prepared in response to an initial Notice of
Violation (NOV), Incident # 1004 7 issued to Mr. J B. Collins with regard to as release
from an undergroundstorage tank (US7) at hisfarni dated April 7, 199.3 (Attachment 1).
Several earlier investigations were conducted by Piedmont Environmental, Inc. in an
attenipt to define the characteristics of the release during the remainder of 1993 and
early 1994, with reports submitted to the North Carolina Division of Environmental
Management (DEM) on June 22,199-3 and November 30,1993. Additional information
has been requested,ky the DEM as as result of the previous reports. A second NOV was
issued to Mr. Collins in November, 199-3 (Attachment 2). A Site Asse,"ment Report ivas
generated as as result qf the additional requested information and also in an attempt to
include the results of pre vious work in order to establish the practible lateral and vertical
extent of gasoline contamination in soil and groundvvater, Other volatile organic
compounds associated with the gwvoline release are also investigated in this report. DiLv
work is being performed under the non-commercial Trust Fund based upon the UST in
question being classified as afarm tank by CAP pertains only to the releaseftoon the
tank, and does not address the removal qf the tank and disposal of contaminated soil
ftom the tank cavit .y. The reviewer is referred to the Piedmont Environmental, Inc. report
dated June 22, 1993for specific information regarding thefate of those materials.
1.2 LOCATION, BACKGROUND& HISTORY
7-he J. B. Collins Site is located in rural northwestern Rowan County (Figure 1.1 near tile tow"n
of Woodleaf, on St. Andrews Church Road (state road 1950). 7he site consist of about 14.57
acres located on both sides of St. Andrew Church road The larger tract is situated on the east
side of that road, comprising 10-53 acres. Asinaller 4.04 tract issituated on the weststale of the
road, The site is currently occupied 4yfive dwellings, one of which is the Collins residence an

1.3 HISTORY OF RELEASE
Thefollowing summary, is tazl:a nfirom the Piedmont Environmental report datedJune 22, 199.E
and as vo from interviews tvith air. Collins *aa nvirataarr �nt al. The site vvas or ginaa served
lays two gr ound vaat r .saepp4, ivells. The ollirss residence and migrate workers housing ivav
supplied ky as well behind the Collins residence (labeled Collins # 2 in this report). The small
house next to the Collins was served ray, as se aaraate well ea small 2 " well, labeled -1 in this
report). APPro imaatelya Pave years ago, the two, inch well became contaminated by gasoline. Lh
well was disconnected and as water line connected to they Collin as well. In 1,992, an odor was
noticed in the wwFaater from well #1 ('a llina v ''ell). ;A packer was installed in the well at t
in an attempt to pre -vent surface contaminantsfrom entering the well e odor continued In
March, 1993, Mr. Collins removed the 1,-gallon UST, and Piedmont rawvirRcar nentaal was
contracted to test the amen cavityM soils. Those snails wvere found to contain high levels of 1 T ,`
constituents. Later in March, the ollin's well was sampled and 5,8 P l' of benzene was reported
ky the aan akytic aal laboratory. i.s ww ill was stopped l i d gas as as Paataalrl water r source and ea
new well was drilled at feet east (upstope) of the Collins well. This well, designated as Well
later in this document, was tested and no BTEX compounds were detected
The Collins well is alrill d to as depth of 260feet, andproduced as maximum of 90 gprn. the 2-
inch well was drilled to a depth of 160feet, in 1 + . Tlae well produced ed about 3 gpm. Due to low
yield when the well uws being constructed, the well wasshot (explosivesplaced in the ww°all to

2.0 PHYSICAL DIESCRI111TION
The site is located in the Piedmont P ysia graarahic Province of North,Carolina, characterized in
this location by rolling mountain foothills. Topography (Figure .1) isgenerally rolling on
lrlaateaus with steely relief occuring in the vicinity ofprinci cal str°eaarrrs and rivers. ne site is
located on the crest aaf a north -.south trending ridge which is drained by Fourth Creek, which is as
tributar to the South Darla of the aaall in Diver. Dire South Forkflows iratan the Yadkin aaboutfve
miles downstream o the .site. The site is at an elevation ofabout 730feet Bove mean sea lewpel
(rnsl), while Fourth Creek is at can elevation of about 620feet r l Surface relief drops sharpy
on both leading sidles of the ridge. Bedrock is very shallow, qpicalky less than 10 feet
throughout the area. Outcrops are apparent in every area of the site vicinity The outcrops often'
appear as rounded boulders due to spheroidal weathering, which is very common in the
Piedoto at. Defoliation, or sheeting, is another common texturalfeature of the rock units, which
can aaLvo am liorate grcrundwwactter flarw. 1�ydraaulic gradients in this type of relief are generally
w°ery strong and downward.

The site is located in the Charlotte felt of the Piedmont, Province. The Geologic Map of North
Carolina (1985, CGS) :shaaww;s the area to be underlain lays units of metamorphic rr aaa c raga . r

equalproportions with, minor visible quartz-.- " sed upon examination of outcrops near the
faarrrr. the Piedmont report is supported in identification of the rock type as predominant'predominant'v dioite.
The rock exhibits a strong lineation texture.
The Piedmont report aalso identifies as straarag regionalJoint pattern in the site vicinity, which is
vety evident in the drainage pattern of Fourth Creel:. The pr a arrr matt, car pattern tart s
northeastinorthwest, which is consistent to thef-racture pattern of thesouthern Piedinont,
According to the Piedmont EnviraamnentaaI repcart ..'ftaaa Lure truce analysis cannot be used to as
much to predict the direction caf`conttaantiraaar t rai, ration as to indicate the presence of such

micraafrcactures in the reach create as high degree arf sec°aaradaa _. porcrsit , in the neck, which gaffers ai
highly, effective conduitfor the vertical and lateral rwrigrration of released contaminants—,
The mature of the highlyfractured ctt red rock at the site, oupl d with loydrar-ftaacturin of the rock lad
previous drilling activities, has likely contributed to contaminant migration to the= twofortner
drinking water er wells. Purraping fraain these wells over the period oftime involved has likely
captured the plurrae from extensive down -gradient migration. A survey offtaacture lineaments is
shown on Figure 3. Two prominentjoint seas are a iwinguisheal the strongest trending W,, and
the second tta the northeast. 7ie first set is better manifested in stream valleys„ and can be
readily associated with strong off -sets in Fourth Creek and the Yadkin Bauer. l e secondser i
better observed along stream valleys, ridge shapes and ridge tarps, and is consistent with the
regional structural trend of the Charlotte belt in this location, Other less prominent sets trend
roughkv in an east - west manner, and are less pronounced unless where intersecting with the
major sets, forming rough blocks of terraaim Most of the major ridges in the area are associated
with these blacks.

The following discussion describes in moredctail each of thy: st-Aected options, their
principal conceptual design components, safety features, maintenance and operational
feasibility and as schedule for implementation of the individual components.
This section oudines-, in detail the recommended program for groundwater extraction and
treatment.
The design of this system is tyased to as large degree upon our collective ex perience in they
hydraulic characteristics of shallow groundwater in Piedmont soils. Yield from recovery
wells in tight Piedmont soils are generally on the order less than .5 to gallons per
minute for any one producing well. The low yield is due, to to transraissivity of
Piedmont soil, generally on the order of [0 to 20 square feet per day. Although these
soils can often reach hydraulic conductivity values for as given, monitoring well
approaching I O'cni/sec, the overall heterogenity of the zone to he pumpe-d can often
result in a shallow aquifer hydraulic conductivity of 10r5to Wctn/sec. For this re, --x-)n, as
steady state radius of influence can take months to years- in approaching as maximum
Capture one sufficient to significantly impact capture of the plume. Considering the size.
of the plume, and also the rapid recharge of the monitonng wells during development
and purging, we recommend that, a pilot recovery system he imstalled consisting of a
recovery well (OW-t) at the, location shown of Figure 7.1 A groundwater analytical
model was used to simulate as pumping wellwith an aquifer transmisSsivity of 2,0 sf/d, a
pumping rate of .5-1 gpm, and as hydraulic gradient of k 125. Porosity was estinrated at
.25. The, results of this homogenous analytical model (WHPA) indicates that a capture
zone of about 50 feet can be established, from the well in a period of about 180 days
(Figure Z2). Actual results and pumping rates from the pilot test will be used to further
calibrate the model. Effluent from OW- I will be discharged to the remedial UVB systern
for contaminant removal (Figure Z3). This information can, then be used to:

. t.2 RECOVERYWELL LOCATION
The location of the recovery well(Figure is chosen basedupon the site layout and
the nixed of having a well in the downgrradient portion of the plume and also a wel'l i
proximity to the higher conee. tration area f the plume. The well is positioned to ont of
plume migration as well as collect contaminated eater for treatment and to also serve, a
an indication of the feasibility of groundwater injection nand/or i liltna .ion. There. also
cutrently exist a pumping well in this location which can serve as a recovery ell. The
current well has already been abandoned as a functional potable water supply.

main consideration, in the selection of the proposed system is the relatively simple and
compact manner in which the systemcan operate. This is especially significant
considering the proximity, of the effected areas to nc tal far, m operations and exposure
pathways to working personnel. The low concentrations of contaminants ts expected in the
system effluents are not near to ex plosive levels, although the equipment. that we chose

ill be explosion proof" The electrical components and the lines to the recovery pump
will be installed by a licensed l trician, Level, sensors in, the recovery ell will cut the
system off ith the absence of sufficient water to extract. All systcmcomponents will be
insulated to inhibit freezing.
All eonduiftsmd manifolds will be berried and not accessible to contact by farm
personnel.
7.4 ' ST
The system monitoring program will consist of sampling of pre-treatment, system
effluent and influent and also post -treatment discharge water. A system of pie ometers
will also be installed at localities around the facility intersecting the groundwater table,
such that static water levels can be monitored as an indication of system perform, a
This testing will be accomplished on a minimum monthlybasis for the initial year of
operation. During the first 'month of system start-up this monitoring well be conducted
bi-y effluent and influent water will be analyzed for EPA Method
compounds. In addition, discharge water will be analyzed for pH, biological oxygen
demand , chemical oxygen demand (COD) and total suspended solids T -
A.dd tional, testing of any permit parameters as specified in the plants discharge permit
gill also be conducted. GeoEnvironmentat will forward the results of the system

The, system mortitoring programwill consist of sampling of pre-treatment system:
effluent and influent and also post -treatment discharge water. A system of pic ;parr et r
will also be, installed at localities around the facility intersecting the groundwater table,
such that static water levels can 1bc;monitored as an indication of system performance,.
This testing will be accomplished can a t ininru rr monthly basis for the, initial year o
operation. During the fiat month of system start-up this monitoring will he conducted
hi -weekly: The effluent and influent water will he, analyzed for EPA Method 6,0
compounds, In addition, discharge water will be analyzed for PH, biological oxygen
demand (BO , chemical oxygen demand (COD) and total suspendedsolids (TSS).
Additional testing of any permit Parameters as specified in the plants discharge permit
will also be conducted, Geo nvirom-nent l will forward the results of the system
monitoring to the NCDEHNR on a calendar quarterly basis.

The groundwater treatment system is being designed to clean up soil and
groundwater iccoitannnation in the "low water tableaquifer consisting of silty
clay suprolite. In addition icotitam'hated water extracted from a down gradie m
pumping well will be. introduced into the ishallow groundwater treatment system
for treatment and subsequent release at the water itable,
The groundwater level is 4 feet below ground surface.. to bripaeted aquifer
thickness is i assumed toy 18' feet from ground s ur. I.* -ace for the water table,

to of expan:4on. When the bubbles reach the water / air interface inside, the well
casing they burst and allow the VDUs to Ix- transported roethetbe w(_-,ll,,"b'Ift and
up to the cuff- gas treatment AuWit, or atmosphere by the air flow., After -the bubbles
burst, the groundwater then falls along the walls of the well and produces a
sig nificant hydraulic pressure,, forcing the water horizontally into the, aquifer
through the tap <r screen secti on at the to of the aquifer.
Groundwater flows into the lower part of the well to comIvnsate for the water
removal from, the upper section. Thus, a vertical circulation develops wilh water
entering the screen in the lower pail of, the wen, or the lx)ttom of the aquifer, and
leaving tbrouO, the upperscreen segment, or the. toof the aquifer. The expected
VOC concentratiom leaving the circulation cell arcsignificantly lower than the
influent hydrocarbon concentrations. As the system functions over time the VOC
concentrations are repmsented ky a -reduction curve which eventuaits ,,reacbes
asymptotic levels at or approaching North Cawliia action levels for the
contaminants present.
The majo6ty of the treated groundwater leaving The lower screensection of the
well circulates ithrough the entire sphere of irit'luence, and returns to the -upper
screen section a number of times before exiting thecirculadon cell. Since the
treated groundwater leaving, the UVB well is almost saturated withoxyen the
effluent groundwater enriches the emetic wme with dissolved oxygen thus
enhancing aerobic biodegra", ion throughout the circulation cell.
