The site consists of an area of contaminated soil behind the Moore's Transmission and Auto Repair Shop (Moore's). The site can be found on the Gastonia South, North Carolina USGS 7.5' Quadrangle Map at latitude 35· 13' 56" N and 81 ° 13' 08" ; W. Prior to 1960, the site was owned by Mr. John Birch of Gastonia, who operated a service station on-site. Mr. Carl Bell, 2916 Burnt Mill Road, Charlotte, purchased the property in about 1960. During the time period from 1960 to 1979 a service station was operated on the premises; however, the identity of the actual operator is unclear. In 1979 or 1980, he leased the property to Mr. Roy Moore, who currently operates a transmission rebuild and repair facility on-site. The property is now part of Mr. Bells estate. · Several samples were collected from soils behind the Moore's operation close to a drain line which exits the rear of the building. These soils were highly contaminated with PCE and TCE. The drain line was installed when Acme Petroleum installed service bays in the shop portion of the service station. A holding tank was to be installed, but, when bedrock was encountered at 2-3 feet, the tank was not installed. Based on this information, the North Carolina Superfund Section believes discharges from the drain line have contaminated the soils and subsequently the groundwater behind the Moore's operation. The area of soils contamination has not been fully delineated; however, sampling has shown that the area is approximately 0.6 square foot and the area of stained soils appears to be approximately 5 square feet. In March of 1990 during routine sampling of the community well at the Cedar Oak Park Subdivision, and again in April 1990, high levels of trichloroethylene (TCE) and tetrachloroethylene (PCE)were detected in the groundwater. During follow-up sampling by the Gaston County Health Department (GCH), three other private residential wells were also found to be contaminated. The North Carolina Division of Environmental Management (DEM) performed extensive sampling of the private wells in the vicinity of the site from May 1990 to August 1992. Most of the domestic water supplies, industrial supplies, and several municipal supplies in Gaston County are obtained from wells. Dug wells, usually found in older, rural areas, derive their water from the saprolite which is the weathered and disintegrated zone between the soil and the unweathered bedrock. Drilled wells, used for higher yields for industry and municipal use, obtain their water from either granite or schist formations. According to Mr. Mark Durway, the former hydrogeologist for the Gaston County Health Department, the saprolite and the fractun;d bedrock act as a single hydrologic unit. a g u 0 D I D PREScore 4.0 NPL Characteristics Data Collection Form Record Information l.

Dug wells, usually found in older, rural areas, derive their water from the saprolite, which is the weathered and disintegrated zone between the soil and the unweathered bedrock. Drilled wells, used for higher yields for industry and municipal use, obtain their water from either granite or schist fonrations. The saprolite and the bedrock act as a single hydrological unit in this area.

The private wells are contaminated with TCE and the farthest downgradient well, the corrmunity well, has a high level of TCE and a low level of PCE in it (Ref. 6, pp. 12-15). Since PCE degrades into TCE and 1,2-DCE, the transmission shop is suspected of being the origin of the groundwater contamination (Ref 8, pp. 206).

We arrived at the site at 9:30. Mr. Roy Moore, owner of Moore's Automatic Transmission and Auto Repair Shop (Moore's) met with us and discussed our sampling plan. We proceeded to an area behind the shop an prepared to collect the first source sample. We used the Hnu 970165 with probe R721, calibrated at a span of 6.66. The calibration reading was 50 ppm. We proceeded to sample in a depression area where we suspected the drain pipe terminated. After hand augering to approximately 2'-0" with no indication of-any contamination, we asked .Mr. Moore to verify the location of the end of the drain pipe. Mr. Moore showed us an approximately 2" diameter pipe coming through the,wall of the shop at ground level, and projecting 3" from the wall.' We relocated an collected sample DR-002-SB from 1 1 south of the pipe. The soil was oil stained to 18" deep. We collected the soil sample from 18" to 24" deep. The sample was collected_ at 10: 10 and no reading was detected on the Hnu. Sample DR-003-SB was collected 2' west of the pipe. Red sandy clay was encountered to a depth of 20". The sample was collected from 20'' to 26'' depth, and again was oil stained. The sample was collected at 10:25 and no reading was detected on the Hnu. After trying to sample 18" northwest of the pipe'. and encountering rock at about 1" depth, Sample DR-004-SB was collected from 9 11 west of the pipe. Clean looking soil was removed to a depth of 18". Oil stained soil was removed to a depth.of 24" where rock was again encountered. The sample was collected from the 18" to 24" depth, however not enough soil was available to collect a duplicate sample. The sample was collected at 10:45 and no reading was detected on the Hnu. We obtained the background soil sample, DR-001-SB, from the southeast corner of the property, approximately 8" southwest of the water meter, at a depth of 6". The sample was collected at 11:05 and no reading was detected on the HNu. ~ ;111 ill) i ' .II Ill ,Ill II The residence of Mrs. Doris Corella is located at 2403 Davis Park Road. Nobody was home at the time, however, Mrs. Corella had given us prior approval to sample her well. Upon initial inspection no well could be located. We suspected that the wellhead may be buried, since the water supply lines located in the crawlspace under the house just appeared and could not be traced to any area. We proceeded to purge-the well at a tap on the southeast corner of the house. We checked the Ph, temperature, and specific conductivity at 5 minute intervals to determine if the groundwater has stabilized. During the purging, we investigated an old wooden shed located approximately 135 feet south of the house, and next to an abandoned house. The well supplying the Corella residence is housed in this shed. A tap was located after a holding tank but before a filter system on the line feeding the· house. · The parameters were checked on water obtained at the tap and were found to have stabilized after 25 minutes of purging. A sample was collected at 12:10. The Cedar Oak Subdivision community well was located on the south side of the subdivision. The pump was connected to an open two inch line with a tap prior to the end. A four inch diameter piece of flexible pvc piping was placed over the open end of the pipe to carry the purge water · outside the wellhouse. Mr. Doc Thompson, Gaston County Health Department, had told us earlier in the day that the secondary. well supplying the subdivision with water had been pumped dry the-day before. When the pump was turned on a significant flow of water, approximately 25 to 30 gallons of water per minute was being discharged. Because of the fear. of pumping the well dry, we sampled the well after ten minutes' of purging, since the parameters had stabilized at this time. The sample was collected at 12: 40 and a duplicate was collected at 12:50. Mr. Godwin, 2231 Davis Park Road, directed us to a tap on the northeast corner of his house. This tap is the closest to the wellhead that does not go through the filtering system which treats the water used in the house. The well was purged for .15 minutes until the parameters stabilized. The sample was collected· at 14:45. Nobody was home at the Philbeck residence, 2301 Davis Park Road, however, Mrs. Philbeck had previously given us permission'to sample the weli. A tap was located at the wellhead. The well was purged for 10 minutes until the parameters stabilized. The sample was collected at 15:40. Mr. Charles May, 2419 Davis Park Road, was summoned to his fence due to the presence of a somewhat friendly Malamute. Mr. May introduced us to his dog and proceeded to show us to the wellhead. A new galvanized tap had been placed between the wellhead and the waterline running underground to the house that morning. We purged the well for 15 minutes until the parameters stabilized. The sample was collected at 16:00. Mr. Orlin Tompkins, 2425 Davis Park Road, was home the second time we attempted to sample his well. We had a lengthy discussion concerning the contamination of the groundwater, the responsibility of the former owner to inform Mr. Tompkins about the contamination, and several other matters. Mr. Tompkins then proceeded to show us an accumulation of what appeared to be blue ·green algae growing in the tank on his toilet. Mr. Tompkins requested that we take a sample of his water inside the house at his sink tap as well as a sample outside at the wellhead. I informed Mr. Tompkins that we are limited to the number of samples authorized on the approved sampling plan, however, I would recommend to the NC DEM and the Gaston County Health Department that this sampling could be done by them. We proceeded to the wellhead in the back yard. The parameters stabilized after 15 minutes, and we collected the sample at 16:50.

First I located the community wells supplied by the N.C. Public Water Supply Section on the topographic maps and delineated those houses associated with them. Several community wells which do not serve over 30 people are identified on Figure 2. These wells and the Cedar Oak Park Subdivision population was determined by house counts on Figure 2. Next I delineated the area of Gastonia served by the Gaston Water Supply System. Several areas depicted as urban areas on the topographic maps, pink with no individual houses shown, are located within the TDL's and are not served by the Gaston Water Supply System. These areas were planimetered and the area (sq. mi.) was multiplied by the population density (315.3 people/sq. mi.) for South Gastonia. TDL AREA (sq.mi.)

Reference 11 I spoke with Mr. Randy Prillaman, Hydrogeologist, NC DEM (919) 715-6187. He said that the Wellhead Protection Area implementation plan written by him and submitted to US EPA in late December 1994 has been approved. This plan calls for prntection of a whole area based on a calculation using recharge rate and pumping rate as variables. North Carolina now has primacy in approval of wellhead protection areas. None have yet been implemented. The Rural Water Association is preparing to submit several applications for wellhead proptection, but none have yet been received or approved. Some areas he expects to be the first to have wellhead protection areas are Gaston County, the Town of Black Mountain, and numerous small communities affiliated with the North Carolina Rural Water Association. Gaston County has delineated wells and completed a contaminant source inventory. . d! i: di 1i dl di I di Reference 12 NORTH CAROLINA DEPARTMENT OF CONSERVATION AND DEVELOPMENT . -DIVISION_ OF ~HNER_AL RESOU_RCES -i .:·_, ','. ·: -·,./ ,_,0 ,,,;, \),jj/lfU1ff'ffi'i~~;~fiiiljf ~if ?lf II il~f i di .

GEOLOGY AND CJWUND \VATEJ\ IN THE CJL\J\LOTTE AnEA 1 Nrnn11 ('.AJ<OLfN,\ GASTON COUNTY (Area, ;:;ss square miles; population i~1 1950, 110,S3GJ Geography and phy:,.;iog-raphy.-Gasto11 County lies in the south-central part of the Charlotte area. Gastonia1 with a population of 2:3,003, is the largest municipality and the county scat. '1':~xtile manufac- turing is the largest industry in the county although I.here is ConsitlCrable farming activity. The cOunty is \vcll served by railroads and paved roads. Gaston County is a rolling upland portion of the Piedmont province, the general altitude b~ing slight- ly more _than 800 feet. Some of the strcan1s have incised their vulle·ys as mm.:h as 200· feet below the up- land, and as a result the topography near the streams is quite hilly. Rising several hundred feet above the general level of the country are several pronounced northeast trending ridges, all of which are composed of resistant quartzite. Prominent among these are Kings fdountain Pinn~1cle, Crowders 1\tountain, and Spencer 1\·Iountain. The county is drained by Catawba River, which flows south along the east boundary. The main tribu- taries of the Catawba flow southeastward across the general trend of the rocks and for the most part are not noticeably influe11ced by any differential resistance of rocks to erosion. The tributaries arc closely spaced, resulting in a fine-textured draina.ge pattern and the absence of extensive, flat interstream areas. With the exception of South Fork Catawba River, the streams have fairly short steep courses, and conse- quently are rather swift. Gcolog-y.-l\'umerous types of rocks occur in Gaston County (fig. 13), and their relations one with au- other are complex. The general northeaSt"sCi1istose structure prevails so that rocks of eastern -Cleveland County exten,l northeastward into the western part of Gaston. Mica schist forms the dominant host rock_ into which the granite was injected in Casto:, County. Nat- urally enough, the granite did not intrude the schist evenly and in a few areas granite is either scant or ab- sent in the schist. The belt of schist 2 miles east of Gastonia and parts of the schist near Kings Mountain Pinnacle and Cro,vders Mountain contain very little granite. Muscovite or sericite, and quartz are generally the chief components of the schist although manganese and chlorite are not uncommon. Composite rocks in which mica schist and granite are interlayered, generally in northeasV trending belts, arc widespread in the western two-thirds of the county. The largest belt in which the schist is pre- dominant surrounds Kings Mountain Pinnacle and extends through the western side of Bessemer City to High Shoals in the northern part of the county. The schist is subordinate in quantity to the granite in· the area between Dallas and Stanley and along the Cleveland County line southeast of Cherryville. Several masses or belts of homogeneous or nearly homogeneous granite occur in Gaston County. The largest of these extends northward from the basin of South Crowders Creek at the South Carolina line, through Gastonia lo Lincoln County east of High Shoals. One finger of this mass extends southwestward to Bessemer City where it is the type locality for Keith's Bessemer granite." Another large mass of gran- ite occurs southeast of Cherryville. The granites are not uniform in appearance and mineral constituents. The granite.at Bessemer City is locally more gneissic and contains more biotite than most of the granite in the county .. The granites for the most part have a light color and medium texture, although small bodies within the complex pr9per are coarse textured and niay be called pegmatite. · Gneisses and schists, containing hornblende as a prominent dark mineral, are common in Gaston Coun- ty. In addition to the numerous lenses of hornblendic rocks interlayered with other country rocks, several '·· large areas of hornblende gneiss occur. One of these, in the vicinity of Beaverdam Creek in the northwest- ern part of the county, has been studied in some detail.'° Soils derived from the hornblende gneiss are gen- erally dark brown or ~ed in color and are more fertile than those from other rocks. ' A composite rock in which diorite and granite appear as intermixed bodies occurs in a gener1:I north- south belt along the eastern border of the county. This belt extends eastward into Mecklenburg· County ~-Keith, .,\rthur, op, cit .. p. ,L ~"Kesler, T. L., Correlation ol some metamorphic;_ ro<'Ks in the central Carolina Pie<lmont: Geo!.

The roe.ks of the complex arc not well exposed, and as a _eon:-;cquence their relation with aclj:teent rocks to lht.: west is nut l'.Crtain. In this eonncelion1 a zone ot' diorite and diorite gneiss extending northeastward through Lowell is adjacent to the complex and may ue genetically ,related to it. South of Mt. Holly the amount of granite appears to be subordinate to diorite but northward the dio-rite is subordinate in amount. Pronounced granular disintegration is charncteristic of both components of the complex in the Charlotte area. Several northeast-trending belts of quartzite occur in the .central part of Gaston Counly. The ridges that they form by their resistance to erosion serve to show the liroad structural trends of the rocks. ln the area south of Crowclers Mountain, Keith" has noted three divisions of the quartzite, nanwly kyanite quartz. ite, white, nearly pure quartzite, chloritic quartzite, and seritic quartzite. The bed:; of quartzite arc con-sidered to be of the same general age, but the relation of one with another is not clear. Ground Wutur.-Most of the domestic water supplies, many of the industrial supplies, and two of the municipal supplies in Gaston County are· obtained from wells (fig. 14). Most of the water in rural sec-tions comes from dug wells that derive water fro1n the weathered and disintegrated zone between the soil .and the underlying unweathered rock. Where the unweathered rock lies near the surface difficulty· may arise in digging a well deep enough to obtain a dependable well. The failure of dug wells is not confined to any one rock type although attempts to dig wells on upland areas underlain by quartzite are likely to be unsuccessful. Records of more than 200 drilled wells are included in the table of well data. The records of 151 wells were complete enough for use in compiling table_ll below.

As the spacing between the different rocks can be 111Casured in terms of reei ancl inches it is inevitable that many wells pass through rocks other than that indicated at the I.op of thr well. The schist is composed of 111uscovite and quartz in most places, but iL 1nay contain beds of 1iorll-bicncle gneiss and schist, pegmatites, and other rocks. Table 11 indicates that the average depth of wells in schist is 180 feet and that the average yield i, 2:~ gallons a minute; this compares with an average depth of 165 feet in granite and an average yield ot 1S gallons a minute. If average yield per foot of well is considered, the water-yielding characteristics of the schist is only slightly greater than that of granite. The average yield of wells in both schist and granite is 21 gallons a minute, which is 4 gallons a minute higher than the average for all wells in the Charlotte area. It is not certain that the higher yield of wells. in Gaston County is significant because the same general geology and topography occur also in Lincoln and Cleveland Counties. The part of table 11 showing the relation of average yield and average yield per foot of well to the topography is signitieant. Wells located on hills have by far the smallest average yield and average yield per foot of well. In addition 7 percent of the wells on hills in the county yield l gallon a minute or less. As is the case in the Charlotte area as a whole, the wells on hills yield only about half as much water per foot of well as wells·in draws. Analyses of samples of water from nine wells and one spring in Gaston County are given in a table following the well records. All but well 97 penetrated schist or granite or both.schist anci granite. Well U7 penetrated both granite and diorile. The water ranged in hardness from 26 to 158 parts per million. The iron content ranged from 0.08 to 8.6 parts per million. Water from different wells in the towns of Cherryville and Stanley showed a considerable local variation in content of iron. Analysis of water from one spring is shown in the table. This water contained only 59 parts per mil-lion of dissolved solicls, despite the fact that it flows from hornblende gneiss, one of the most readily soluble rocks of the Charlotte area. The low mineral content of this spring 'Yater is thought to· be typical inasmuch as water from springs normally flows through the rocks more rapidly than water from wells. Temperatures of waters ranged from 60" to 66° F. and averaged 62°.F. Tiie water havine; a tempera-ture of 66° F. is pumped from a well 1,053 feet deep. There are two municipally owned ground-water supplies in Gaston County; in addition the town of McAdenville is supplied with water from a well owned and operated by a mill. Cherryville, population 3,486, obtains its water from eight wells in various parts of the town. Ali the wells penetrate granite. The wells range from 132 to 238 feet in depth and from 10 to 75 gallons a mi:i~ ute in yield. · Six of the wells yield approximately 20 gallons a minute each. The chemical quality of the . water is good. The total dissolved ·solids of the water froin any of the wells_ does not exceed 115 parts per million. The water receives no regular treatment. . .. Stanley, population 1,645, obtains its supply from four wells. Three of the wells are at least :J50 feet deep. They vary in yield from 15 to 45 gallons a minute .. The water from the ·four wells co,itains more than the average amount of mineral matter for all wells in the county and is slightly hard; the water from well 10 contained 4.9 parts per million of iron on November 20, 1947. The water is not treated. tilt.·· _ McAdenville, population 1,059, is supplied with water from ~ well ow'.1ed by Stowe Mills, Inc. The Lt;:.. . well, 132, is 523 feet deep and yields in excess of 100 gallons a mmute. A field test showed the water had i:>-• a total hardness of 230 parts per million.

DATE: TO: FRCM: December 23, 1993 File Harry Zinn, Environmental Engineer North Carolina DEHNR, Superfund Section RE: Hydrogeology of Gastonia Area Davis Park Road TCE Site Gastonia, Gaston County, North Carolina NO) 986 175 644 Reference 13 On December 22, 1993 I talked to Mr. Mark Durway (704-868- 3743), the former Hydrogeologist for Gaston County Health Department, Environmental Health Section from 1991 to 1993, about the hydrogeology in the vicinity of South Gastonia and specifically the Davis Park Road site. Mr. Durway stated that. in the area of concern, there is no confining layer between the saprolite (weathered bedrock) and the bedrock. The majority of the potable water is obtained from fractures in the bedrock. His conclusion is supported in three ways. First, this is based on all of the current literature available on the local geology. Second, it is supported by field observations of the stratigraphy in the area in the vicinities of bedrock outcrops and stream bed cuts. Finally, it ,is supported by personal geologic experience in the area during his three years in this area.

This data base serves as a repository for general information about NPL sites and is used to respond to queries about NPL sites from a variety of sources including the general public, the press, other government agencies, and members of Congress. The primary source materials for completing this form are Regional site file documents (e.g., PA and SI reports), along with the site's HRS scoring package. Although inuch of the information needed to complete the form is expected to be available in the HRS scoring package, other sources in a site file may need to be consulted for some questions.· If definitive data are not ·available in the site file to answer a question, estimates based on best professional judgment and other sources o.f information are acceptable. As you complete tbe NPL Characteristics Da.ta Collection Form, keep the following points in mind. !> Please complete ihe form in ink, and print legibly. > Use the most accurate level of information available (e.g., SI-level information has priority over PA-level information). · l> Try to use the listed response options when answering a question, and use "unknown" ~nd "other" responses only when absolutely n=sary. If, however, the available'response op.lions for a question·are not adequate to accurately describe the site, use the "other" respon_se and provide a brief ex-planation in the space provided. !> Use the margins to explain responses that do not match listed response options or to provide clarifying information. If you need additional room to clarify responses, use the space provided in Appendix C. !> Some questions may go beyond tbe scope of the HRS scoring package (e.g., may relate to pathways not scored). Answer these questions witb tbe best information available, making reasonable "educated guesses' if necessary. > "Current," as used in this form, should be interpreted as the general time period of HRS scoring package preparation. !> · "Principal contamination," as used in this form, should be interpreted·as tlie contamination that is primarily responsible for a site's proposal to the NPL · Please respond to all questions with the answer that you believe best represents the site conditions, given the information available at the time of HRS scoring package preparation.
