We represent Mr. David Krug, the owner of property located
at the corner of East Seventh Street and Caswell Road in
Charlotte, North Carolina. Your office should already have afileonthispropertyfrompreviouscorrespondencerelatedto
underground storage tanks removed from the property. Mr. Setzer
served as DEM's contact person for earlier correspondence
concerning the property, but we assume you are now the propercontactperson.
Our understanding is that DEM previously determined that Mr.
Krug is not the owner or operator of the tanks previously locatedontheproperty. Nonetheless, Mr. Krug is proceeding on a
voluntary basis to attempt to complete closure of the tanks. At
the request of Mr. Krug, we have enclosed a Comprehensive SiteAssessment ("CSA") prepared by Shield Environmental for review byDEM. Although Mr. Krug assumes no responsibility in this matter, Mr. Krug would like to move ahead with preparation of a
Corrective Action Plan upon receipt of DEM's approval of the CSA.
Please call with your questions or comments.
With best regards.
very truly yours,
ROBINSON, BRADSHAW & HINSON, P.A.

1 Executive Summary
Type: Petroleum hydrocarbon constituents are present in the groundwater at the site.
Containers: Site previously dispensed gasoline and diesel. The products were dispensed
via pumps connected to USTs.
Amount: No data is available to indicate the quantity of product released at the site.
Initial Abatement and Emergency Response
Tank Closure: 4n March 22, 1992, seven underground storage tanks (USTs) were
removed from the site. The capacities and contents of the USTs were as follows:
1) 10,000-gallon gasoline
2) 4,000-gallon gasoline
3) 2,600-gallon gasoline
1) 1,000-gallon gasoline/diesel
Soil Removal: Approximately 825 cubic yards of soil was removed during closure
activities and disposed at an approved land application facility. Known contamination
was left on -site due to excavation restrictions. All known concentrations are below the
site specific clean-up levels except for areas under sidewalks or roads at the Caswell
Road right of way.
Free Product: No free product petroleum was detected.
Water Supply: There are no active water supply wells in close proximity to the site.
Re`sidences and businesses in the immediate vicinity are provided potable water by the
City of Charlotte.
1 Damage/Extent of Release and Affected Receptors
Potential Receptors: There are no surface water intakes within 0.5 miles of the site.
Subsurface Structures: No known basements or vaults are located in close proximity
to the site.

1.0 SITE HISTORY AND SOURCE CHARACTERIZATION
1.1 History of Property Ownership
The Krug Property (Krug's) is located at the corner of 7th Street and Caswell Road in Charlotte,
Mecklenburg County, North Carolina. The Site Location Map (Figure 1) shows the United
States Geological Survey Topographical Quadrangle Map for the area and indicates the site
location. Krug's has in the past, prior to ownership by Mr. Krug, been the location of a
business which dispensed gasoline and diesel as a commercial enterprise.
The surrounding area has been zoned residential and commercial. Figure 2 is the County Road
Map, indicating the site location (Section 35 - Lots 9-11) and the location of adjacent property
owners. An itemized list of the adjacent property owners is shown as Table 1.
1.2 Release Incidents and Environmental Investigations
There were originally seven USTs on site which were permanently closed March 22, 1992 (see
Figure 3 - Site Plan for former UST locations). The April 9, 1992 "Underground Storage Tank
Closure Report" (see Appendix A) prepared by Atlantic Environmental Services (Atlantic) lists
the tanks as:
1 10,000 gallon gasoline
2 4,000 gallon gasoline
3 2,600 gallon gasoline
1 1,000 gallon gasoline / diesel
During the UST removal, apparent hydrocarbon contamination was noted in the soil at several
of the UST locations. The soil exhibited elevated soil vapor readings when screened with a
Tank Techtor Organic Vapor Analyzer (OVA). Subsequently, approximately 825 cubic yards
of soil was removed during closure activities. According to the Atlantic report, soil
contamination associated with the site was left at several locations:
1,000 gallon UST - "Approximately 100 cubic yards of
contaminated soil under tanks removed and disposed. Closure
samples indicated soil contamination at 20 to 22 feet below the
surface. Removal was suspended because excavation depth was at
the depth of groundwater. "

4,000 gallon USTs - "Approximately 200 cubic yards of
contaminated soil under tanks removed and disposed. Closure
samples indicate that all soil contamination was removed except at
a small area next to the sidewalk. Removal was suspended
because excavation depth was at groundwater depth and [because
of] the possible structural failure of the sidewalk."
2,600 gallon USTs - "Approximately 300 cubic yards of
contaminated soil under tanks removed and disposed. Closure
samples indicate that all soil contamination was removed except at
the property boundary and at one area where excavation depth was
at groundwater depth... Remaining contamination in the sidewals
of the 2,600 gallon tanks exists on City of Charlotte property or
occurs at a depth that cannot be removed with typical excavation
equipment. "
2
The above closure activities conducted in February and March of 1992 at Krug's indicated the
presence of total petroleum hydrocarbons (TPH) that exceeded the 10 parts per million (ppm)
action limit established by the North Carolina Division of Environmental Management
NCDEM). Known remaining soils containing hydrocarbons are below roads or sidewalks or
are at concentrations below SSE clean-up levels. Figure 4 shows the soil sample locations for
the UST closure. Based upon those analytical results, Shield was contracted by Krug to perform
a Comprehensive Site Assessment of the site.
The purpose of this report is to provide the results of the assessment and to present Shield's
conclusions and recommendations.
2.0 POTENTIAL RECEPTORS AND NUGRATION PATHWAYS
2.1 Water Supplies Within 1,500 Feet
Field reconnaissance activities were conducted during December 1992 to locate drinking water
well users (see Appendix B for Receptor Survey). There are no apparent water supply wells
WSW's) in close proximity to the site.
2.2 Surface Water Intakes Within 0.5 Mile
There are no surface water intakes within 0.5 miles of the site.

Shield Number 930014
2.3 Subsurface Utilities
Although the groundwater is shallow in this area, the subsurface utilities are not indicated as
probable off -site migration "conduits." Subsurface utilities on and in the vicinity of the site do
not intersect known soil or groundwater contamination.
2.4 Availability of Municipal Water
Krug's and the adjacent properties are supplied with water by the City of Charlotte. Other
businesses in the immediate vicinity appear to be provided potable water from the same system.
2.5 Potential Impacts
To date, all analysis indicates that potable water supplies within 1,500 feet of the plume do not
appear to be at risk.
3.0 SOILS INVESTIGATION
3.1 Site Soils and Geology
Regional Geology - The aquifer underlying the site is typical of the composite weathered
residuum -fractured crystalline rock aquifers that occur within the Piedmont region of North
Carolina. The aquifer is unconfined, existing in phreatic or water table conditions. Under these
conditions, the water table surface is in equilibrium with the atmospheric pressure and is not
confined by low -permeability layers between the surface of the water table and the surface of
the ground. Groundwater, under water table conditions, is typically recharged by direct
infiltration from precipitation. This water flows through pore spaces of the geologic media to
its ultimate discharge in topographic low regions where the surface of the water table intersects
the ground. As a result of these typical flow patterns, the potentiometric (water table) surface
expressed by water table aquifers typically appears as a subdued replica of the land surface
topography.
Site Soils - Boring samples indicate that the soils are inhomogeneous inorganic clays and sandy
silts. These soils are thought to be formed by in -place weathering of the parent rock rather than
deposited by water. See Figure 4 for location of USTs and Soil Sampling Locations.

Shield Number 930014
Soil contamination extent has been defined and has either been addressed by off -site landfarm
activities or has been left in place as outlined in the Atlantic report. Table 2 gives the field
screening and laboratory data for soils. A Site Sensitivity Evaluation (SSE) is given as Appendix
C. The SSE final cleanup level for soils has been calculated to be 300 ppm. Soil contamination
originally existed in three distinct areas:
Location 1 - area of 10,000/1,000-gallon USTs
no soils above SSE final cleanup levels
Location 2 - area of 4,000-gallon USTs
no soils above SSE final cleanup levels
Location 3 - area of 2,600-gallon UST
soil exists above SSE final cleanup levels beneath sidewalks/ roads
3.2 Migration and Attenuation of Contaminants
Migration - Silt and clay particles formed by in -place weathering in the Piedmont typically have
a higher horizontal conductivity than vertical hydraulic conductivity. As a result, hydrocarbon
contaminants with specific gravities less than water tend to migrate preferentially in a horizontal
direction.
Attenuation - Clays and silts tend to adsorb gasoline range hydrocarbons. The adsorption
produces a smearing of the contaminants across the phreatic interface as the water table
fluctuates. In addition, hydrocarbon concentrations may be expected to diminish as the plume
moves downgradient due to dispersion, adsorption and biodegradation.
4.0 GROUNDWATER OWMTIGAT.ION
4.1 Monitor Wells
4.1.1 Number and Construction of Wells
Four Type II monitoring wells were installed at the locations shown on Figure S. These wells
were installed in order to identify and determine the horizontal extent of the petroleum
hydrocarbon plume apparently released from the USTs previously excavated and removed from
the site. These wells were installed in unconsolidated material composed primarily of clays.
The annulus for each well was advanced with a rotary drill rig using 4-1/4-inch hollow stem
augers. All augers were decontaminated between borings with high pressure steam. The
construction of each well was completed by installing a 2-inch PVC well screen and PVC riser
pipe in each boring. The annulus around this pipe was filled with filter sand material to a depth

of 1 foot above the screen. A bentonite seal was placed above the filter sand and the rest of the
annulus was filled to ground surface with grout. Refer to Appendix D for well construction
records.
One Type III well was completed into competent bedrock in order to establish the vertical extent
of contamination. The well was placed in a location closest to the shallow monitoring well
exhibiting the highest contaminant levels.
Table 3 summarizes the well construction details, screening intervals, and potentiometric data.
Figure 5 gives a potentiometric surface map of the area. Appendix D gives the well construction
records and soil descriptions.

Horizontal Extent
Groundwater samples from monitoring wells MW-3 and MW-4 show results below the North
Carolina groundwater quality standards, NCAC T15A O2L.0202 (2L standards). A total VOC
Isoconcentration map is provided as Figure 6. Laboratory analysis of groundwater samples from
monitoring wells MW-1 and MW-2 showed that they exceeded the 2L standards for various
compounds. (See Table 4 - Laboratory Data for Groundwater)
Appendix E contains the laboratory reports and chain of custody records. Quality Assurance
protocols are given in Appendix F.
Vertical Extent
A vertical extent well (VEW-1) was installed at Krug's. The 6-inch PVC outer casing was set
at 70 feet below grade level (BGL) in fractured bedrock. During the installation of the 2-inch
inner casing, the outer casing was punctured by the auger. While trying to remove the auger,
the outer casing was cracked, torn, and dislodged. The well was completed even though it was
suspect. A groundwater sample was collected from that well. Upon receipt of laboratory
results, it was determined by Shield that cross -contamination from the upper water bearing zone
likely occurred and that the sample is not reliable or representative of the lower aquifer (as
discussed with Mr. A. Schiff of the Mooresville Regional Office (MRO) of the NCDEM). It was
agreed that VEW-1 should be grouted up and a subsequent attempt should be made to install a
new VEW.

On June 1, 1994, a second vertical extent well was installed (VEW-2) using steel outer casing.
The well was successfully installed at a total depth of 93 feet BGL. A groundwater sample was
analyzed for constituents of concern, all of which were non -detect (ND). The results indicate
that the vertical extent of contamination has been defined. A geologic cross-section of the area
is provided as Figure 7.
4.2 Plume Characteristics
4.2.1 Physical
Potentiometric surface data has consistently indicated groundwater flow toward the west. The
general shape and concentration of the plume indicate an east to west groundwater flow.
4.2.2 Chemical
Primarily, benzene, toluene, ethylbenzene, and xylenes (BTEX) constituents have affected the
groundwater. These compounds have a specific gravity less than 1.0 and can be expected to
float" on water. Additionally they will adsorb to clay particles. Chlorinated hydrocarbons
were also detected in the groundwater samples.
The values of all detections were mathematically added in order to give total VOC's
concentration for each sampling point. An Isoconcentration Contour Map of Total VOC's
Groundwater Contamination was then overlaid on the site plan (see Figure 6). Table 4 provides
a summary of the laboratory data for groundwater.
4.2.3 Features Affecting Flow Patterns and Plume Migration
The most significant feature affecting flow patterns is the topography of the area. The land is
generally flat in the area of the site but falls off gradually to the west and rises up gradually to
the east. The groundwater flow apparently follows this general topography (refer to Figure 1).
4.3 Hydrogeologic Conditions
A survey of the top of the well casings and depth to groundwater measurements was performed
to calculate the groundwater elevations, gradient, and flow direction at Krug's. Table 3 contains
a summary of groundwater elevation data. Figure 5 shows the groundwater movement is
generally to the west. Groundwater gradient calculations showed an average gradient of
approximately .008 ft/ft, which was fairly uniform across the site.

Information about the soil porosity and permeability was collected by performing slug tests on
MW-1 and MW-3 and by an infiltration test (Figure 8). Slug tests were performed by measuring
the static water level in each well and then removing as much water as possible. The recovering
water level was measured until it returned to at least 80 % of its static level. The water level
measurements and time are plotted on semi -logarithmic graph paper and the point that is 37 %
less than the static level was used to determine the time value to be used in the hydraulic
conductivity calculations. The hydraulic conductivity (K-value) value calculated for MW-1 was
0.292 ft/day. The K-value for MW-3 was 0.222 ft/day. (See Appendix G - Slug Test
Calculations)
An infiltration test was performed by excavating a hole approximately 3 feet x 3 feet x 3 feet
deep. Ten gallons of water were poured into the excavation to saturate the underlying soils.
A 6-inch inside diameter cylinder was driven into the soil and the cylinder was filled with water
and allowed to stand overnight. The cylinder was then refilled and the water level was measured
and water was allowed to infiltrate into the saturated soils beneath the cylinder. After several
hours, water was poured into the cylinder to the initial measurement height and the added water
volume was recorded. Using the inside surface area of the soil in the cylinder, the volume of
water added and the time elapsed, an infiltration rate of 1.79 x 101 gpm/fe was calculated.
4.3.1 Confining Beds

Total soil contamination removed and disposed, 825 cubic yards.
II. Field Screening Methods:
All excavated soils were screened using a Tank Techtor Organic Vapor Analyzer (OVA)
by Atlantic Environmental Services. The OVA indicated hydrocarbon contamination at
the tank locations described in Section 1. Probable Sources of Contamination.
Contaminated soils were excavated to a depth of 18 to 22 feet or to where the OVA
indicated hydrocarbons to be less than 10 parts per million, at which point Atlantic
Environmental suspended the stockpiling of contaminated soils and obtained a closure
sample.
III. ClosureSamples: Closure
samples were collected using the bucket of the backhoe for a 'grab' sample or from
a stainless steel auger. Soil samples were then placed into a laboratory jar, sealed with
a teflon cap, labeled, and placed into a cooler with ice for delivery to PAR Laboratories.
A Chain of Custody was delivered to the lab along with the respective samples.
All samples were analyzed for Total Petroleum Hydrocarbons (TPH) using EPA methods
3550 and 5030.

VIII. Quantity of Soil Excavated
Approximately 825 cubic yards of contaminated soil was removed and disposed of from
all tank locations. Soil was transported to the Stillwell Farm located North of Dallas,
North Carolina, for landfarming treatment by Atlantic Environmental Services (permit
pending).

IIX. Summary
All sources of contamination found at this property have been removed. The majority
of the contaminated soil was excavated and replaced with clean backfill pit'gravel and
soil. Remaining contamination in the sidewalls of the 2,600 gallon tanks exists on City
of Charlotte property or occurs at a depth that cannot be removed with typical
excavation equipment.
Ten (10) closure samples indicate various concentrations of TPH contamination. The
contamination indicated by these samples cannot be removed for the following reasons:
1. Depth of closure sample is at the depth of groundwater, as in the case of
samples 8, 9, and 10 of the 1000 gallon tank; samples 2 and 6 of the 4000
gallon tanks, a and b, and samples 1, 6, and 9 of the 2600 gallon tank.
2. Contamination exists on the adjacent property owned by the City of Charlotte
or is in the City of Charlotte right-of-way, as is the case of samples 3 and 7 of
the two 2600 gallon tanks.
3. Possible structural failure of the storage barn and sidewalk, as is the case for soil
samples 9 and 10 of the 10,000 gallon tank; sample 6 of the 4000 gallon tank;
samples 3 and 7 of the 2600 gallon tanks.

L PRELEM3NARY ACTIVITIES
L 1. INTRODUCTION
Prior to any drilling activities, visit and inspect the site. This will enable the project manager
to effectively plan the field work phase of the project. Prior to making the site visit, ask the
client whether a scaled site map of the location to be drilled currently exists. If so, obtain one
prior to visiting the site. If not, prepare one during the initial site visit.
I. 2. PREPARE A SITE SKETCH
a. Show locations of roads, overhead lines, developed areas, and other potential
obstructions.
b. Show locations of underground storage tanks (note tank sizes), product lines and
product dispensers.
C. Locate utility manholes and/or valve covers. Common utilities to be located
include water, power, gas, telephone, storm sewer and sanitary sewer. Also note
apparent electrical conduit connections to signs, light poles, etc. If necessary,
using a line locator, locate service lines leading to the building.
d. Consider traffic flow in relation to probable drilling rig setup. If traffic flow will
continue during drilling activities, consider possible ways to restrict public access
while maintaining smooth traffic flow.
e. Designate an auger decontamination area and temporary soil storage area for soils
generated during drilling activities. If possible, locate the auger decontamination
area near a water spigot.
L 3. LOCATE PUBLIC UTILITIES
a. Contact the public utilities' location service prior to drilling activities. Inquire
whether service lines are located as part of the service, and if so, specify that
service lines be painted.
b. Obtain location service plans from utility companies as needed.

II. SOIL SAMPLING PROCEDURES
II.1. INTRODUCTION
Soil samples are generally collected by one of two methods: 1) by split spoon sampling in
conjunction with standard penetration testing in accordance with ASTM D-1586, or 2) by Shelby
tube, whereby the sampling device is forced into the soil at specified intervals. All site
supervision, borehole logging and soil sampling will be performed by an on -site qualified
geologist, engineer or scientist.
Soil sampling is most often performed using a truck -mounted rotary power auger system
equipped with 8 or 11 inch O.D. continuous flight hollow stem augers. Soil sampling depth and
1
1 Quality Assurance & Quality
Control Procedures

sampling intervals are usually specified by the client. If no specification has been made, collect
the initial sample at a depth of 2 feet below grade level (BGL), the second sample at 5 feet BGL
and at intervals of 5 feet thereafter, until auger refusal is met, maximum depth specified is
achieved or the capabilities of the power auger system are exceeded.
All persons collecting and handling the soil samples must wear disposable latex gloves.
II. 2. PREPARATION FOR SAMPLING
Perform the following steps prior to arrival at the job site:
a. Prepare labels that identify the project name, project number, project location,
assigned sample collector and borehole number. Prepare three labels PER
SAMPLING INTERVAL: one label should be attached to the plastic ziplock bag
and two labels should be attached to the sampling jars to identify the sample.
The labels placed onto the sampling jars should partly overlap the lid and sample
jar, forming a tamper seal over the jar and lid.
b. Prepare sample containers. If the soil samples are to be tested for total petroleum
hydrocarbons (TPI), a minimum of two 4 oz. glass sampling jars with teflon
lined lids PER SAMPLING INTERVAL will be needed. If additional analyses
are to be performed, prepare specific sample containers and labels as required by
the laboratory.
C. Prepare laboratory shipper container (LSC) for sample storage. The LSC should
be chilled to approximately 4 degrees centigrade using ice. The ice should be
kept in a plastic ziplock soil sample bag that will not allow water to come in
contact with the sample containers. Vermiculite or foam can be placed in the
cooler in order to cushion sample. containers, thereby minimizing the chance for
breakage.
d. Prepare Chain -of -Custody form.
e. Prepare field to and/or field book. g
II. 3. FIELD PROCEDURES
a. Clean the augers, split spoon samplers and/or Shelby tubes with a steam -cleaner
or high pressure washer prior to drilling activities. Allow augers and samplers
to dry before proceeding.
1
1
u
1
Quality Assurance & Quality
Control Procedures
January, 1994
b. Locate the sample handling point away from running motors or where discharged
vapors and fumes may come in contact with the sample. Place towels, field
meters, sample jars and other equipment so that they do not come in contact with
soil or other materials that may contaminate the sampled soils. DO NOT place
any equipment on the ground unless a ground cloth is used.
C. As the sample is withdrawn from the borehole, all personnel will handle the
sample using clean, disposable latex gloves. Immediately upon opening the
sample tube, discard the obvious "cave-in" portion of the sample (approximately
the top 3 inches.) Next, split the sample lengthwise into two identical halves.
One half is to be immediately packed into 4 oz. sample jars with Teflon lined
lids. Take care to completely fill the jars, leaving no headspace between the soil
sample and the Teflon lined lids. A lithologic description of the replicate sample
will be prepared and recorded on the boring log and/or field notebook. Then the
replicate sample will be removed from the sampler and placed in a plastic ziplock
bag. If the entire sample cannot be placed into the plastic ziplock bag, again
replicate the sample by splitting it lengthwise, placing equal halves into separate
plastic ziplock bags. Transfer the sample into the plastic ziplock bag in such a
manner as to preclude loss of possible volatile organic compounds.
d. Immediately place the previously prepared labels on the soil sampling jars and the
plastic ziplock bag. Then place all sample jars into a LSC pre -chilled to
approximately 4 degrees centigrade.
e. During the sampling process, collect one duplicate sample for every six sampling
locations. Duplicate samples are considered to be two replicates, prepared by
dividing the sample into two separate aliquots. Split the sample into equal
portions, making both portions representative of the entire sample.
f. After the sample has had sufficient time to disperse volatiles into the headspace
of the plastic ziplock bag, perform a scan of the headspace using an organic vapor
analyzer (OVA). The field scan is performed by opening a small portion of the
plastic ziplock bag and inserting the OVA probe into the headspace of the bag.
Take care to prevent soil from entering the OVA probe. Note reading(s) on
boring long and/or field book.
g. After completion of the steps outlined above, place all sampling jars that contain
soil samples to be laboratory analyzed in the LSC in individual plastic ziplock
bags. If any samples are suspected to be highly contaminated, place a small
amount of activated charcoal in each ziplock plastic bag. This will help prevent
4
Quality Assurance & Quality 5
Control Procedures
January, 1994
cross -contamination of samples through diffusion.
If. 4. SPECIAL CONSIDERATIONS
When working in hot weather, avoid handling samples in direct sunlight. Heat and direct
sunlight may cause accelerated volatilization of the sample.
II. 5. DECONTAMINATION PROCEDURES
a. The augers MUST BE decontaminated between successive boreholes using a
steam -cleaner or high pressure HOT WATER washer. Take particular care to
remove soil material from inside hollow -stem augers. Store soil material
generated during the cleaning process in the temporary soil stockpile area or in
DOT approved 55 gallon drums.
b. Clean the split spoon soil sampler both inside and outside between successive
samples with a solution of laboratory grade soap (Alconox) and tap water, rinse
with pesticide grade isopropyl alcohol solution, and then rinse with distilled
water. The sampler MUST BE allowed to dry between successive samples.
c. - If Shelby tubes are used, only clean, unused tubes should be used for individual samples.
d. Always replace the disposable latex gloves worn by the sampler handler(s)
between successive samples.
e. Change the sampler cleaning solution between successive borings. If samples
appear to be highly contaminated, change the cleaning solution between sampling
intervals.
II. 6. TRANSPORTATION OF SAMPLES TO LABORATORY
a. The maximum holding time for samples to be tested for volatile organics is 14
days. Therefore, samples must be delivered to the laboratory and analyzed by the
laboratory within this time frame. Consult the laboratory regarding holding times
for other constituents to be tested.
b. If the samples are taken directly to the laboratory from the drill site, transport
them in the same LSC at a temperature of approximately 4 degrees centigrade.
C. If the samples cannot be taken directly to the lab, take them to the project office.
Upon arrival, immediately transfer the sample containers from the LSC to the
Quality Assurance & Quality
Control Procedures
January, 1994
assigned refrigerator, pre -cooled to approximately 4 degrees centigrade, until such
a time that they can be taken to the laboratory.
d. When the samples are scheduled to be delivered to the lab, transfer them from the
refrigerator to a LSC pre -chilled to a temperature of approximately 4 degrees
centigrade, where they will remain until they are delivered.
III. MONITORING WELL GAUGING PROCEDURES
M. 1. INTRODUCTION
6
Well monitoring is necessary to provide information on a) depth to water in the monitoring well,
and b) whether liquid phase separated hydrocarbons (PSH) are present. IfPSH are present, the
thickness of the floating layer must be determined.
M. 2. MEASUREMENT OF WATER LEVELS AND PSH LEVELS
a. Before each gauging event, open the monitoring well and let it stand for
approximately 30 minutes to allow the liquid level(s) in the well to stabilize to
atmospheric pressure. After the well has stabilized, take an initial measurement
of PSH level and/or water level using a clean water level meter or interface
probe. Record values on the monitor well gauge report.
b. Clean the interface probe and/or water level meter between each successive well.
To clean the equipment, first wash it in a soap solution (Alconox) and distilled
water, rinse with a pesticide grade isopropyl alcohol solution, then rinse with
distilled water.
C. If PSH are present, purge each well of liquid PSH using a new disposable bailer,
and place the liquid in an appropriate container. Lower the bailer gently into the
well, so that the bailer does not impact hard on the liquid surface (this may cause
emulsification of the hydrocarbon layer). Allow the bailer to fill (approximately
1 foot) and retrieve quickly. Repeat this process until the PSH are removed or
until the hydrocarbon thickness cannot be further reduced by bailing. Record the
total volume of liquid PSH removed on the field sheet; do not include water.
d. Some monitoring wells accumulate exaggerated thicknesses of PSH. Therefore,
it is necessary to allow the wells to recover (24 hours maximum) before
rechecking water and PSH levels.
Quality Assurance & Quality
Control Procedures
January, 1994
e. Amex well recovery, gauge the wells a second time using the procedures in
III.2.a. above. Do not remove PSH again.
f . The groundwater, PSH and potentiometric surface elevations will be calculated
later by the Project Geologist.
IV. WELL PURGING PROCEDURES
1V.1. INTRODUCTION
7
Monitoring wells are purged a) both shortly after the well has been constructed and b) prior to
groundwater quality sampling. After well construction, the well is thoroughly purged in order
to restore the aquifer's hydraulic characteristics, which may have been altered by drilling. Prior
to water quality sampling, the well is purged in order to introduce formation water into the well.
In both cases, the primary reason for well purging is to evacuate the standing water column from
the well. The standing water may not be representative of the actual on -site groundwater
quality. Therefore, both the standing water in the casing and in the filter pack must be removed
in order to allow more representative formation water to enter the well.
TV. 2. PURGING PROCEDURE (Bailing and Pumping)
a. During the purging procedure, maintain a field sheet for each well.
b. The well is initially checked for the presence of liquid phase separated
hydrocarbons (PSH). If PSH are present, follow the procedures outlined in
Monitoring Well Gauging Procedures," page 7.
c. Prior to pumping, the Project Geologist should estimate the approximate well
volume, and consider the casing pipe diameter, casing depth and the backfilled
annular space diameter, if known (if unknown, assume a 10-inch annulus).
d. Evacuate low -yield wells to dryness once. The pumping rate should be slow,
allowing recharge water to slowly enter the well, minimizing the degree of
agitation to the formation water, thereby reducing volatilization. For high -yield
wells, remove at least three well volumes from the well. At a minimum, note the
number of well volumes on the log sheet. Note more detailed information if
available.
e. Purge the well using either a disposable bailer or a pump. The pumping method
C'
Quality Assurance & Quality
Control Procedures
January, 1994
is preferred since it is much faster than the bailing method.
1. Pump Method
Remove the water by means of a disposable hose extending to the bottom of the
well casing. Water is continuously drawn from the bottom of the well until the
well is dry, or until an appropriate volume of water has been removed. Take
care not to introduce dirty hoses into the well. Drain hoses thoroughly between
successive wells and dispose of them.
2. Bailing Method
Remove the water utilizing a clean, disposable bailer with a bottom ball check
valve. Lower the bailer into the well by means of a string, and bring the water
to the surface. Allow the bailer to drop to the bottom of the well each time in
order to evacuate the well from the bottom. Replace the bailer and string
between each successive well.
IV. 3. DECONTAMINATION PROCEDURES
a. Disposable hoses must be changed between wells.
8
b. Clean the bailer (if not disposable) with a soap solution (Alconox), rinse with
isopropyl alcohol, and then rinse with distilled water.
C. Change the bailer line between each successive well. Do not let the bailer touch
the ground before or during the purging process.
IV. 4. GENERAL CONSIDERATIONS
The cleaning solution and distilled water are contained in plastic jugs. If the cleaning solution
is poured into a bucket for use in cleaning the equipment, thoroughly clean the bucket with the
solution prior to use at the next well location.

Prior to water quality sampling, gauge the well for the presence of PSH. If PSH are present,
the client may not request water quality samples to be collected since hydrocarbons are obviously
present. If the well is to be sampled, the well MUST be purged (see "Well Purging
Procedures"), and allowed to recharge fully. Water sampling must be performed within 24
hours from the time the well was purged.
Disposable latex gloves are to be worn by all persons collecting and handling the samples.

should be carried with the samples throughout the sampling, storage, shipping and
testing process.
C. Prepare labels identifying project, project number, project location, assigned
sample collector and monitoring well number. Prepare two labels PER SAMPLE
to be used as follows: one label attached to the container identifying the sample;
one label placed partly over the lid and partly on the sample container to form a
tamper seal over the container lid.
d. Prepare sample containers. Use containers that are clean and unused. If samples
are collected for analysis of volatile organics, a minimum of three standard 40-m1
glass screw -cap VOA vials with teflon-faced septums will be needed PER
SAMPLE LOCATION. If additional analyses are to be performed, prepare
specific sample containers as directed by the analytical laboratory.

L To monitor possible contamination, place a trip blank (obtained from the
analytical laboratory or prepared from distilled, de -ionized water) in the LSC
prior to placement of any samples. Carry this blank with the samples throughout
the sampling, storage, shipping and testing process. Some clients require a rinse
blank to be obtained by collecting the rinsate from a clean, disposable bailer.
g. Prepare Chain -of -Custody forms.
h. Prepare field log and/or field book.
V.3 FIELD PROCEDURES
a. Locate the sample handling point away from running motors or where discharged
vapors and fumes may come in contact with the sample. Place towels, field
meters, sample containers and other equipment so that they do not come into
contact with soil or other materials that may contaminate the water samples. DO
NOT place any equipment on the ground unless a ground cloth is used.
b. Collect water quality samples using either a disposable bailer with a bottom ball
check valve or a peristaltic pump with disposable hoses.
1. Sample Collection Using Bailer
a. If a nondisposable bailer is used, it must be decontaminated prior
to sampling. To decontaminate the bailer, first wash in a soap
solution (Alconox), rinse with pesticide grade isopropyl alcohol,
then rinse with distilled water, in that order. The bailer MUST be
allowed to dry before collecting the next sample. Use either a
teflon coated string or a new string of inert material. This string
will be changed on each individual well. Follow this
decontamination procedure between successive sampling points.
b. Gently lower the bailer into the water. Personnel must wear clean,
disposable latex gloves during this procedure. Gently lowering the
bailer will reduce gassification and maximize the size of the
collected sample. After the bailer is lowered into the water, let the
sample stabilize for approximately 3 seconds, which will allow the
ball valve to close properly. Gently raise the bailer to the surface.
It is preferable that the actual water surface be inspected for PSH,
so take care not to overfill the bailer.

C. Once the sample has been withdrawn, pour the water into the
sample vials in such a manner as to minimize agitation, which may
drive off volatile compounds. Do not introduce air into the vial
while the sample is being poured. If bubbling occurs as a result
of violent pouring, the sample must be poured out and refilled.
Fill each vial until there is a meniscus over the lip of the vial.
Tighten the screw-top lid with the teflon septum (white toward the
sample) on the vial. After the lid is tightened, invert and tap the
vial to check for the presence of trapped air bubbles. If bubbles
are present, retake the sample.
2. Sample Collection Using a Peristaltic Pump
If a peristaltic pump is used, change the hose between successive sampling points.
a. Submerge the hose such that the upper 12 inches of the standing
water column is sampled. Be sure that the hose is submerged deep
enough that the system does not take on air. Once the water is
pumped to the surface, discharge the sample from the discharge
hose directly into the sample vials. Since the pumping rate will be
a steady flow, the sample collector must be prepared by having a
sufficient number of containers ready to collect the sample as it is
discharged.
b. Once the sample is discharged into the vials, handle the sample as
described under "Sample Collection Using a Bailer."
C. Immediately note the project number, monitoring well number,
sampling interval, date and time on two labels as soon as the
sample is placed in the container. Use permanent marker, not
pencil, on the labels. Place one label on the container to identify
the sample. Place a second label over the lid, overlapping the
container, so as to form a tamper seal. Put each sample container
in a separate plastic ziplock bag and immediately transfer them to
the LSC. An airspace left in the plastic ziplock bag will help
cushion the sample containers.
d. Collect one duplicate sample for every six sampling locations
during the sampling process. Duplicate samples are considered to
be two replicates, and are prepared by dividing the sample into
11

Control Procedures

two separate aliquots. In order to duplicate the sample as closely
as possible, prepare six sample vials and fill all six vials from a
single bail of sample. Tag alternate vials as the sample and the
duplicate (ex: vial 1 is sample, vial 2 is duplicate, vial 3 is sample,
vial 4 is duplicate, vial 5 is sample, and vial 6 duplicate).
C. After completion of the steps outlined above, place all sample
containers in the LSC in individual plastic ziplock bags. If the
samples are suspected to be highly contaminated, place a small
amount of activated charcoal in each plastic ziplock bag. This will
help prevent cross -contamination of samples through diffusion.
f. Prepare Chain -of -Custody forms.
g. Prepare field log and/or field book.
V. 4. SPECIAL CONSIDERATIONS
12
When working in hot weather, avoid handling samples in direct sunlight. Heat and direct
sunlight may cause accelerated volatization of the sample.
V. 5. TRANSPORTATION OF SAMPLES TO LABORATORY
a. The maximum holding time for samples to be tested for volatile organics is 14
days. Therefore, samples must be delivered to the laboratory and analyzed by the
laboratory within this time frame. Consult the laboratory concerning holding
times for other constituents to be tested.
b. If the samples are taken directly to the lab from the drill site, they should be held
in the same LSC, at a temperature of 4 degrees centigrade.
C. If the samples cannot be taken directly to the lab, deliver them to the office.
Upon arrival, transfer the sample containers immediately from the LSC to the
assigned refrigerator pre -cooled to 4 degrees centigrade, until such a time that
they can be taken to the lab. Keep the trip blank with the samples.
d. When the samples are scheduled to be delivered to the lab, transfer them from the
refrigerator to an LSC pre -chilled to a temperature of approximately 4 degrees
centigrade until they are delivered to the lab.

VI. CHAIN -OF -CUSTODY PROCEDURES
a. Prior to any sampling activities, the person conducting the sampling must partially
complete a chain -of -custody report. A purchase order number must be
obtained for every sampling event per location and recorded on the chain -of -
custody form.
b. Immediately upon obtaining the sample, complete the appropriate lines of the
chain -of -custody report for each sample (see attached chain -of -custody). After
all samples are collected for each day's activities, note a specific sample number,
along with shipment and laboratory testing and reporting specifics.
C. The Chain -of -Custody report shall accompany each sample group in each
transport LSC. Received by and relinquished by signatures and specifics shall be
completed appropriately. A copy of the chain -of -custody form must be
maintained in the Shield sampling logbook.
