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. 1 LM �♦ CI\VII\CCRII\ First Colony Corporation Law Job No. 229-07757-03 April 15, 1992 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. FA v��• �iwn�ccrtnw First Colony Corporation Law Job No. 229-07757-03 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. 3 LAW ENGI First Colony Corporation Law Job No. 229-07757-03 April 15, 1992 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. 5 LM �♦ CI`/VIIV CCRII`IV TABLE 1 Summary of Field Parameters V��♦ GI`I VII`ILLRII\V TABLE 1 SUMMARY OF FIELD PARAMETERS' Coltsgate Road Site Charlotte, North Carolina Law Job No. 229-07757-03 Specific Well Depth to Conductivity Number Water ft pH Temperature n (umhos/cm) MW-1 12.03 5.6 16 110 M W-2 18.78 5.7 15 190 MW-3 13.54 5.6 15 90 MW-4 5.90 11.1 15 490 ' Wells MW-1, MW-2 and MW-3 were measured on March 14, 1992 Well MW-4 was measured on March 18, 1992 WS\TIyCl&71C1.i-f31KLWi APPENDIX A Test Boring Records LAW CrvVI KEY TO CLASSIFICATIONS AND SYMBOLS CORRELATION OF PENETRATION RESISTANCE WITH RELATIVE DENSITY AND CONSISTENCY No. of Blows, N Relative Density* 0 - 4 Very Loose 5 - 10 Loose Sands 11 - 20 Firm 21 - 30 Very Firm 31 - 50 Dense 51+ Very Dense Consistency* 0 - 1 Very Soft 2 - 4 Soft Silts and Clays 5 - 8 Firm 9 - 15 Stiff 16 - 30 Very Stiff 31+ Hard SYMBOLS - Undisturbed Sample (UD) Recovered 50=211 - Number of Blows (50) to Drive the Spoon a Number of Inches (2) BQ,NX,NQ,NW - Core Barrel Sizes Which Obtain Cores 1-7/16, 2-1/8 Inches, 1-7/8 Inches, 2-1/16 Inches in Diameter, Respectively 65% - Percentage (65) of Rock Core Recovered (Compared to Cored Length) RQD - Rock Quality Designation - Percentage of Recovered Cored Length Consisting of Moderately Hard or Better Core Segments 4 or More Inches Long Z - Water Table Approximately 24 Hours or More After Drilling 1 - Water Table Approximately at Time of Drilling (Within 1 Hour) - Loss of Drilling Fluid *Terminology may be altered if presence of gravel, cobbles or boulders interferes with accurate measurement of standard penetration resistances LM♦♦ GIY V11`ICCRIIYV DEPTH DESCRIPTION (FT.) 0.0 0.6 MW# 17.0 27.0 ELEVATION (FT.)
