1.0 PROJECT INFORMATION
Two 250-gallon home heating oil underground storage tanks (USTs) were noted during the
site walkover performed by our Mr. David Jerose as part of a Preliminary Environmental
Site Assessment (Law Job No. 229-07757-01) at the Coltsgate Road Site in Charlotte, North
Carolina.
Due to expected construction activities at the site, the USTs were scheduled for removal.
Law Engineering was requested to observe and document the tank excavation activities and
collect soil samples for laboratory analysis.
The two 250-gallon USTs were excavated and removed from the site by Curbmaster Inc. on
January 10, 1992. The soils in the excavations appeared discolored and a strong fuel oil
odor was noted. Based on our observations, soil samples (Block-1 and Block-2) were
collected at 13 feet at the base of the excavations. As authorized, Law Engineering also
contacted the North Carolina Division of Environmental Management (DEM) to notify
them of a potential release.
Apparent petroleum contaminated soils (approximately 65 cubic yards) were stockpiled on
plastic sheeting at the site. Analytical results of the soil samples from the base of the
excavations indicated that total petroleum hydrocarbons (semi-volatiles) were present in
sample Block-1. No petroleum hydrocarbons were noted in sample Block-2. Based on the
results from Block-1, additional excavation activities were performed on January 15, 1992.
Based on the results of the laboratory analysis of the soils and onsite observations, a
temporary observation well (TW-1, Figure 1) was installed downgradient from the tank
excavation (Block 1). The laboratory results (EPA Method 610) indicated the presence of
naphthalene at 86 parts per billion (ppb), 1-methylnaphthalene at 89 ppb and 1-
methylnaphthalene at 55 ppb in the ground water.
The above project information was based on a telephone conversation between our Mr.
David Jerose and Mr. Hayden McMahon of First Colony Corporation on January 8, 1992,
the Report of Preliminary Environmental Site Assessment (report dated December 26, 1991)
and the Report of Underground Storage Tank Closure (report dated February 5, 1992)
performed by Law Engineering.

2.0 FIELD EXPLORATION
2.1 Soil Test Borines
Four soil test borings (MW-1, MW-2, MW-3 and MW-4) were drilled at the approximate
locations identified on the Monitoring Well Location Plan (Figure 1). The borings were
advanced by mechanically twisting a continuous -flight hollow stem steel auger into the soil.
Soil sampling and penetration testing was performed in general accordance with ASTM D
1586. Soil samples were obtained at assigned intervals with a standard 1.4-inch I.D., 2-inch
O.D., split -tube sampler. The sampler was first seated 6 inches to penetrate any loose
cuttings, and then driven an additional 12 inches with blows of a 140-pound hammer falling
30 inches. The number of hammer blows required to drive the sampler the final 12 inches
was recorded and designated the "penetration resistance".
Representative portions of the soil samples were placed in glass jars and transported to our
soils laboratory where they were examined by a geologist to verify the driller's field
classifications. Test Boring Records, showing soil descriptions and penetration resistances,
are included in Appendix A. To minimize the potential for cross -contamination to occur
between borings, the down -hole drilling equipment was steam cleaned prior to drilling each
boring.
2.2 Monitoring Well Installation
Type II monitoring wells (MW-1, MW-2 and MW-3) were installed at the approximate
locations shown on the Monitoring Well Location Plan (Figure 1). The wells consisted of
2-inch diameter Schedule 40 PVC pipe with flush -threaded joints inserted into an 8-inch
diameter augered borehole. The bottom 10-foot section of wells MW-1 and MW-2 and the
bottom 15-foot section of well MW-3 consisted of manufactured well screen with 0.010-inch
wide openings. The screens in these wells were placed so that the time -of -drilling water
level was within the upper half of the screen. Washed sand backfill was placed around the
outside of the pipe to at least two feet above the top of the well screen. The sand backfill
was used to stabilize the formation and to help yield a less turbid ground -water sample. An
approximately two foot thick bentonite seal was placed on top of the sand to prevent surface
water from entering the well. The remainder of each borehole was grouted with a
cement/bentonite mixture to the ground surface.

April 15, 1992
A Type III monitoring well was installed in boring MW-4. An 8-inch diameter borehole was
advanced through the overburden soils to a depth of 36 feet using hollow stem augers.
Four -inch diameter PVC pipe was installed to the termination depth in the boring. After
installation of the casing, the borehole and the PVC pipe in well MW-4 was grouted to near
ground surface using a cement/bentonite grout. After the grout had cured for at least 24
hours, a 3 7/8-inch diameter borehole was advanced to approximately ten feet below the
bottom of the 4-inch casing (46 feet).
Two-inch diameter PVC casing with a 5-foot (0.010-inch slots) screened section was installed
at the bottom of MW-4 through the 4-inch casing and into the washed borehole. A sand
pack was placed around the outside of the pipe to at least one foot above the top of the
well screen followed by a bentonite seal (minimum 1-foot thick). Above the bentonite seal,
the annular space was filled with a cement/bentonite grout mixture to the surface.
A lockable steel protective cover was placed over each well. Details of the monitoring well
installations are illustrated on the Monitoring Well Installation Records included in
Appendix B. The monitoring wells were installed in accordance with the North Carolina
Well Construction Regulations and Standards.
2.3 Well Development and Ground -Water Sampling
Wells are developed to remove suspended solids and to return water flow through the well
to natural conditions. Development took place immediately after installation. The water
level was allowed to stabilize and was then measured with an electronic water level
indicator. The volume of water in each well was calculated and the wells were developed
by extracting a quantity of water equal to approximately three volumes from each Type II
well and to dryness twice in well MW-4, in accordance with our understanding of current
North Carolina Division of Environmental Management (DEM) guidelines.
The wells were sampled using bailers constructed of 3-ft long, 1.6-inch diameter teflon pipe.
To minimize the potential for cross -contamination between wells, the bailers were cleaned
with laboratory soap, rinsed with distilled water, rinsed with dilute nitric acid and, finally,
rinsed with distilled water before developing and sampling each well.
Immediately prior to the recovery of water samples from the wells, pH, temperature and
specific conductivity measurements were recorded in the field. Field measurement of the
sample temperature was made using a mercury thermometer. Field measurement of pH was
conducted with a portable pH meter and specific conductivity was measured with a
conductivity meter. The field measurements for these wells are summarized in Table 1.

The pH level in well MW-4 measured at 11.1 is in the alkaline range of pH. We suspect
the elevated pH may be influenced by the grout in the well.
The well samples were placed in the appropriate containers, labeled, appropriately
preserved, and shipped overnight to Law Environmental National Laboratories (LENL) in
Kennesaw, Georgia where they were analyzed for polynuclear aromatic hydrocarbons (EPA
Method 610). As part of our quality assurance procedures, a bailer rinse blank was also
shipped to the laboratory for chemical testing by the same method. Chain -of -custody
procedures were maintained.
3.0 REGIONAL HYDROGEOLOGY
The site is located within the Charlotte Belt of the Piedmont Physiographic Province. Based
on the Geologic Map of the Charlotte 10 X 2 Quadrangle, North Carolina and South
Carolina dated 1988, the site is underlain by rocks consisting of metamorphosed granodiorite
of Devonian age and metavolcanic rocks of Late Proterozoic age. No major geologic
features are documented in published literature in the site area.
The topography of the Piedmont is characterized by low, rounded hills and gentle slopes.
A variably thick layer of residual soils and weathered rock (saprolite) caps the underlying
bedrock (metavolcanic rocks and granodiorite). Ground -water movement is often related
to topography, lithology, elevation of recharge and discharge areas and man-made
influences. Ground water generally flows laterally and downward toward local drainage
features that have eroded deeply enough to intersect the water table, thus creating a
discharge point for ground water. Ground water in the underlying bedrock is controlled by
fractures. Natural recharge of ground water occurs in upland areas and natural discharge
occurs in the intervening lowlands.
Based on this assumption and our interpretation of the topographic maps and onsite visual
observations, surface run-off and subsurface drainage would be expected to flow northeast
from the site towards an unnamed tributary of McMullen Creek.
4.0 SUBSURFACE CONDITIONS
Residual soils were encountered from the surface to the termination depth in the four
borings (MW-1 through MW-4). A thin veneer of topsoil was encountered in boring MW-1
to a depth of 0.6 feet. The residual soils consisted mostly of soft to firm fine to medium
L,

First Colony Corporation
Law Job No. 229-07757-03
April 15, 1992
sandy silt and soft to firm silt. Boring MW-4 was wash drilled from 36 to 46 feet, no
samples were collected. Water was encountered at 23 feet in MW-1 and at 28 feet in MW-2
at the time of drilling. Borings MW-2 and MW-3 were dry at the time of drilling.
The above descriptions provide a general summary of the subsurface conditions
encountered. The Test Boring Records included in Appendix A contain detailed
information recorded at each boring location. These Test Boring Records represent our
interpretation of the field logs based on examination of the field samples by a geologist.
The lines designating the interfaces between various strata represent approximate
boundaries and the transition between strata may be gradual.
5.0 LABORATORY TEST RESULTS
Analytical results for the four ground -water samples and the bailer rinse blank are included
in Appendix C. No petroleum constituents were detected in these samples.
6.0 COMMENTS AND RECOMMENDATIONS
Based on the laboratory results from wells MW-1 through MW-4, the petroleum
contaminants previously detected in temporary observation well, TW-1 (Report of
Underground Storage Tank Closure, report dated February 5, 1992), appear to be localized
near the former UST location.
Since the concentration levels detected in TW-1 were low, the source of the petroleum
contaminant has been removed and water usage in the area is supplied by the Charlotte -
Mecklenburg Utilities Department (CMUD), Law Engineering recommends no further
ground -water assessment at the Coltsgate Road site. The DEM may recommend additional
sampling and analysis of the ground water to determine if the contaminants have migrated
to the wells.
7.0 QUALIFICATION OF REPORT
The activities and evaluative approaches used in this assessment are consistent with those
normally employed in hydrogeological assessments and waste -management projects of this
type. Our evaluation of site conditions has been based on our understanding of this site,
project information provided to us by First Colony Corporation and the data obtained in our
exploration.
