The work is conducted under the Region 5 Remedial Action Contract (RAC) Program and implemented as a contract crossover to. Region 4, Contract Number 68-W7-0026, Work Assignment Number 138-RALR-04PN. The LTRA includes monitoring the bedrock aquifer contaminant plume by sampling a network of bedrock wells for volatile organic compounds (VOCs) on a quarterly basis for three years and annually thereafter for 27 years to ensure the plume is in fact naturally attenuating. 1.2 BACKGROUND The Davis Park Road TCE Site is located within the Gastonia Extra Territorial Jurisdiction area along Davis Park Road, south of Hudson Boulevard and north of Blackwood Creek in the southwestern portion of Gastonia, Gaston County, North Carolina. The site consists of an area of reportedly contaminated soil behind a building that is located at 2307 Davis Park Road (Davis Park Auto Repair), and a plume of contaminated groundwater that emanates from this property and extends south along Davis Park Road to Blackwood Creek. The site also includes the Cedar Oak Park subdivision located on the east side of Davis Park Road within the confines of Cedar Oak Circle as well as areas along the western side of Davis Park Road. Figure 1-1 presents a site map for the Davis Park Road TCE Site.

Second Quarter Sampling Event Report Davis Park Road TCE Site Section: 1 Revision: 0 Date: January 2003 The plume of contaminated groundwater underlies residential areas along the plume's entire horizontal extent. The contaminant levels and areal extent are further described in Section 1.3.2. At the time of the discovery of contaminants in the groundwater (March 1990), a majority of the residences throughout the site were supplied water by residential water supply wells. As a result of the continued migration of the plume, groundwater supplying many of these residential water wells became contaminated with the chlorinated hydrocarbons found in the plume. Since that time, several neighborhoods within the site have been connected to the Gastonia public water supply to reduce the potential health threat from the contaminants. In 1996, many of the houses within the Hedgewood Circle neighborhood, which borders the northern edge of the site, were connected to the public water supply. In late 1997 and early 1998, after petitioning the city for water services, all of the homes in the Cedar Oak circle subdivision, which dominates the eastern side of the site, were connected to the public water supply. Approximately 130 homes within the site were receiving water from residential water supply wells prior to RA activities. Over half of these homes (approximately 75) had water supply wells that were or could potentially be affected by the contaminant plume as depicted in the 1998 Remedial Investigation (RI) report. In August 2000, five of these residences were supplied with carbon filtration units, and in September 2000, 64 of the residences were connected to the Gastonia public water supply as part of the Remedial Action (RA) to execute the provisions of the Record of Decision (ROD) for the Site. The locations of the residences connected to the Gastonia public water supply and the carbon filtration units are presented in Figures 1-2 and 1-3, respectively. 1.3 GROUNDWATER CONT AMIN ANT DESCRIPTION This section describes the potential source area of the contamination, current knowledge of the groundwater plume, and the extent of the plume.

Analysis of the sample revealed concentrations of TCE (34.9 micrograms per liter [µg/L]), tetrachloroethene (PCE) (23.7 µg/L), and chloroform (9.2 µg/L). A confirmation sample was collected from this well on 17 April 1990, and analytical results were similar to the original sample. Groundwater samples collected from three nearby private wells in May I 990 by the Gaston County Health Department indicated that the groundwater was contaminated with TCE. The highest concentration of TCE (101.4 µg/L) was detected in a sample collected from the private well located at 2419 Davis Park Road, 200 feet south of the Davis Park Auto Repair facility (located at 2307 Davis Park Road). The current EPA Drinking Water Maximum Contaminant Level (MCL) for TCE and PCE is 5 µg/L. Current State (NCDEHNR) MCLs for TCE and PCE are 2.8 µg/L and 0.7 µg/L respectively. Street address locations are shown in Figure 1-4. The Environmental Services Division of EPA collected groundwater samples from the contaminated wells along Davis Park Road and within the Cedar Oak Park subdivision in July 1990. TCE was detected at concentrations of 82 µg/L and 31 µg/L in groundwater sampled from the private well located at 2419 Davis Park Road and a Cedar Oak Park subdivision well, respectively. Additional investigations and groundwater sampling events prior to the initiation of the RI continued to reveal levels of contaminants above State and Federal drinking water standards. Investigation activities focused on a possible source location(s). Several potential sources of the contamination at the Davis Park Road TCE Site were reviewed.

Second Quarter Sampling Event Report Davis Park Road TCE Site Section: 1 Revision: O Date: January 2003 regional and local groundwater flow directions, and groundwater sample analytical data indicated that the Davis Park Road Auto Repair facility was the most likely contaminant source at the Davis Park Road TCE Site (NCDEHNR Site Inspection, 1993). As a result of these findings and in an effort to further define the source area for the water supply well contaminants, environmental assessments were conducted, including the Site Inspection Addendum (SI) (May 1993), Expanded Site Investigation (ESI) (May 1994), and RI (1996- 1998). The RI report summarizes the source investigation as follows: " ... according to data generated from this and previous investigations, solvents such as PCE or TCE were introduced to the environment from the property at 2307 Davis Park Road. This 'spill' migrated through the vadose zone and the saprolite/partially weathered rock aquifer, and into the bedrock aquifer. Once introduced into the environment, various biophysiochemical processes acted on the contaminants to reduce the overall concentration as well as spread the contaminant mass throughout various matrices. Currently, the VOC contaminants, principally TCE and PCE, appear to be present only within the bedrock aquifer and may continue to be drawn towards active residential wells scattered throughout the site, specifically those wells to the west of Davis Park Road." 1.3.2 Groundwater Plume Concentration and Extent Five potential sources for water supply were identified in the Davis Park Road Area and presented in the RI report. These include the following: City of Gastonia Public Water Supply System; City of Gastonia Restricted Use Water Line; water supply well as part of a Community Water System; a water supply well as part of a Private Well System, and private water supply wells. Nine monitor wells were installed during completion of the RI (MW-IS, MW-ID, MW- 2S, MW-2D, MW-3S, MW-3D, MW-4S, MW-4D, and MW-SS). Following connection to City Water in August 2000, seventeen private wells were abandoned, seven wells were converted into K:12006411381Quartertylsecondquarterreport2.doc 1-8 I I I I I I I I I I I I I I I I I I I This document was prepared by Weston Solutions, Inc., expressly for EPA.

Second Quarter Sampling Event Report Davis Park Road TCE Site Section: 1 Revision: O Date: January 2003 monitor wells (CW-1 through CW-7), and five residences were supplied with carbon filtration units (2400 Skyland, 2419 Davis Park Road, 2717 Davis Park Road, 2839 Davis Park Road, and 2639 Springbrook). Figure 1-5 details the locations and water supply source of residences within the vicinity of the Davis Park Road TCE site updated to include activities completed as part of the 1998 R1 and as part of the 2001 RA to execute the provisions of the ROD for the Site. A summary of analytical data for the primary constituents of concern (PCE and TCE) detected in groundwater sampled at the Davis Park Road TCE Site is presented in Table 1-1. Analytical data was obtained for groundwater sampled after August 2001 from the 5 residences supplied with carbon filtration units as part of the RA to execute the provisions of the ROD. This data is included for PCE and TCE in Table 1-1. Based on these data, the contaminant plume is centered along Davis Park Road from Glenraven to Blackwood Creek and underlies areas approximately 500 feet to the east and west of Davis Park Road. 1.4 SITE GEOLOGY AND HYDROGEOLOGY The geologic profile across the site generally consists of a saprolite layer, underlain by a partially weathered rock zone and the underlying fractured crystalline bedrock. The saprolite is a silty, clay-rich, residual material derived from in-place weathering of rock. The saprolite zone appears to be thickest (approximately 80 feet) near the ridge crest along the northern edge of the site, thinning towards the lower elevations or stream valleys to approximately 20 feet in thickness. A partially weathered rock layer typically underlies the saprolite, and ranges in thickness form approximately 5 to 25 feet. This layer is composed of saprolite and fragments of weathered bedrock. The bedrock is generally observed to be a fractured quartz biotite granite or granitic gneiss.

SECTION2 Seoond Quarter Sampling Event Report Davis Park Road TCE Site Section: 2 Revision: O Date: January 2003 LONG TERM RESPONSE ACTION The ROD for the Davis Park Road TCE Site (September 1998) states that following initiation of a natural attenuation study, groundwater monitoring will be conducted on a quarterly basis for three years and annually for the next 27 years. Data obtained from the long term groundwater monitoring will be used to evaluate natural attenuation of contaminant constituents within the bedrock aquifer plume at the Davis Park Road Site following provision of city water to 64 residences in August 2000. In April 2002 a baseline sampling event was conducted to establish current conditions and to evaluate the need for installation of additional wells for the LTRA. Based on analytical results, it was determined that natural attenuation was occurring at rates consistent with expectations, and that the wells currently available for sampling were sufficient to evaluate natural attenuation in long term performance monitoring. A Monitored Natural Attenuation Plan (submitted to EPA in October 2002) was developed to include sampling a network of 18 bedrock wells for VOCs to effectively characterize contaminant levels (VOCs) in the bedrock aquifer within the contaminant plume as well as the surrounding area for the potential migration of contaminants from within the existing groundwater plume. The 18 bedrock wells to be included for groundwater sampling in each LTRA monitoring event include four bedrock monitor wells installed in December 1997 (MW-I through MW-4), the five private wells provided with carbon filtration units in August 2000 (MW-5 through MW-9), two community wells located west of Davis Park Road (MW-10 and MW-11), four converted wells (MW-12 through MW-15), and three private wells (MW-16 through MW-18). Monitor wells MW-2, MW-5, MW-6, MW-9, MW-12, MW-15, MW-16, MW-17, and MW-18 provide groundwater quality information within the contaminant plume. The remaining monitor wells K:120064 \ 138\Quarterty\secondquarterreport2.doc 2-1 I I I I I I I I I I I I I I I I I I I This document was prepared by Weston Solutions, Inc., expressly for EPA. lt shall not be disdosed, in whole or in part, without the express written permission of EPA. Seoond Quarter Sampling Event Report Davis Park Road TCE Site Section: 2 Revision: O Date: January 2003 (MW-I, MW-3, MW-4, MW-7, MW-8, MW-10, MW-11, MW-13, and MW-14), located outside the contaminant plume, provide evidence of potential contaminant migration. Figure 2-1 provides the locations of the monitor well sampling network. Table 2-1 provides monitored natural attenuation sample designations cross-referenced with addresses and former designations. 2.1 OUARTERL Y GROUNDWATER MONITORING The purpose of quarterly groundwater monitoring is to verify the following: • That natural attenuation is occurring at rates according to expectations, • No changing conditions arise that might reduce efficacy of this remedy, • The continued absence of toxic and/or mobile transformation products, • Verification that the plume is not expanding, • Verification that there is no impact downgradient, • Detection of any new releases, and • Verification of attainment of remediation objectives.

Second Quarter Sampling Event Report Davis Park Road TCE Site Section: 2 Revision: O Date: January 2003 The samples are collected in accordance with the following documents: • Final Monitored Natural Attenuation Plan, dated October 2002, and • U.S. Environmental Protection Agency Science and Ecosystem Support Division (EPA- SESD), Region 4, revised Environmental Investigation Standard Operating procedure and Quality Assurance Manual (EISOPQAM), May 1996. All samples are analyzed by laboratories in the Contract Laboratory Program. Samples are analyzed for VOCs. 2.2 FIRST QUARTER LTRA SAMPLING EVENT The first quarter sampling event, performed in April 2002, was originally developed as the baseline event to establish current conditions and to evaluate the need for installation of additional wells. Based on analytical results, it was determined that the wells currently available for sampling were sufficient to evaluate natural attenuation in long term performance monitoring. Thirteen of the 18 wells selected for the sampling network and two additional wells were sampled in the baseline sampling event. Depth to water was recorded where possible (MW-1 through MW-4, MW-12 through MW-15) prior to sampling. Field parameters (pH, specific conductivity, temperature, dissolved oxygen, oxidation reduction potential, and turbidity) were also recorded. Field measurements from the first quarter sampling event are summarized in Table 2-2. Field data sheets are included in Appendix A. Figure 2-2 provides a potentiometric surface map of the bedrock aquifer. The potentiometric map for the bedrock aquifer indicates the groundwater flow direction in the bedrock aquifer ranges from south to east across the site, with the strongest component of flow to the southeast. This is consistent with previously reported data.

Second Quarter Sampling Event Report Davis Park Road TCE Site Section: 2 Revision: 0 Date: January 2003 Analytical data from the first quarterly LTRA sampling event is summarized in Table 2-3. Laboratory analytical reports are included in Appendix B. TCE and PCE concentrations are presented graphically in Figure 2-3 and 2-4, respectively. The highest TCE concentration (14 g/1) was reported for water sampled from residential well MW-9. This well is currently supplied with a carbon filtration unit. TCE concentrations greater than the ROD performance standard (2.8 µg/1) were detected in four wells southeast of MW-9 (i.e., towards Blackwood Creek). The highest PCE concentration (8.6 µg/1) was detected in MW-18, adjacent to Blackwood Creek). PCE concentrations greater than the ROD performance standard ( 1 µg/1) were detected in two wells located in the central portion of the site (MW-12 at 1.6 µg/1 and MW-6 at 1.5 µg/1) and two wells in the southeast portion and toward Blackwood Creek (MW 17 at 5.7 µg/1 and MW-2 at 2.5 µg/1). No other constituents were detected at levels greater than the ROD performance standards. The analytical results suggest the contaminant plume is migrating slightly to the west and also southeast. Concentrations are significantly less than those detected in I 990 for wells in the northern and central portion of the plume. TCE decreased from 101.4 µg/1 in 1990 to 1.4 µg/1 in this sampling event in groundwater sampled from well MW-5, and PCE decreased from 34.9 µg/1 in 1990 to 1.6 µg/1 in this sampling event in groundwater sampled from MW-12. However, concentrations have increased slightly in wells to the west and southeast. TCE increased from 7.4 µg/1 in 2000 to 14 µg/1 in this sampling event in groundwater sampled from MW-9, and PCE increased from I µg/1 in 1990 to 5.7 µg/1 in this sampling event in groundwater sampled from well MW-17. These levels are consistent with a naturally attenuating plume that is shifting due to pumping (community wells on Skyland Drive and Briar Oak Drive located west of the site) and to a groundwater flow direction trending to the southeast and Blackwood Creek.

SECTION 3 Second Quarter Sampling Event Report Davis Par1< Road TCE Site Section: 3 Revision: O Date: January 2003 SECOND QUARTER LTRA SUMMARY 3.1 GROUNDWATERSAMPLING 3.1.1 Monitor Well Sampling WESTON mobilized to the site the week of 23 September 2002. Groundwater samples were collected from the 18-monitor well network from 23 September through 26 September 2002. Monitor wells MW-I through MW-4 and MW-12 through MW-15 were sampled in accordance with Puls and Barcelona (1996) Low-Flow (Minimal Drawdown) Groundwater Sampling Procedures published by the EPA Superfund Technology Support Center for Ground Water using a MicroPurge bladder pump. Water level and field parameter measurements (pH, specific conductivity, temperature, turbidity, dissolved oxygen, and oxidation/reduction potential) were recorded on field data sheets which are included in Appendix A. Pump intake was lowered to well screen depth, and the well was micro-purged until field parameters stabilized. Laboratory samples for VOC analysis were then collected in pre-labeled, pre-preserved sample bottles. Bottles were capped appropriately, placed in a Ziploc-type bag, and stored in an ice cooled container prior to shipment to the CLP designated laboratory, A4 Scientific located in the Woodlands, Texas. All downhole equipment was decontaminated after use in each well. Purge water was collected and transported to stationary containment located on the property behind the Davis Park Auto Repair facility pending sample analysis for determination of method of disposal.

Wells were purged at approximately I gallon per minute for a period of approximately 15 minutes. Turbidity, pH, specific conductivity, temperature, dissolved oxygen, and oxidation/reduction potential were measured approximately every 5 minutes during the purge process. Purging continued until parameters were stable for three successive readings, and samples were collected as described above. Field parameter data sheets are included in Appendix A. 3.1.3 Field Quality Assurance/Quality Control Samples One rinse blank and one field blank were collected during the baseline sampling event. The rinse blank was collected by pouring distilled water over the submersible pump. The field blank was collected proximal to a MW-3 by pouring distilled water directly from the container into the sample container. One field duplicate was collected from MW-8. All samples were analyzed for VOCs using EPA Method 8260. Analytical results for the QNQC samples are summarized in Table 3-1. Chloroform was detected in the trip blanks and also in groundwater samples. Associated groundwater samples for which chloroform was also detected were flagged. Chloroform was not detected at significant levels in any oft he groundwater samples.No other constituents that were detected in blanks were also detected in groundwater samples. Duplicate results were within acceptable relative percent differences.

Field parameters (pH, specific conductivity, temperature, dissolved oxygen, oxidation reduction potential, and turbidity) were recorded during sampling of all wells. Field measurements from the first and second quarter sampling events are summarized in Table 3-2. Field data sheets are included in Appendix A. Figure 3-1 provides a potentiometric surface map of the bedrock aquifer. Consistent with the first quarter LTRA event and previously reported data, groundwater flow direction in the bedrock aquifer appears to range from south to east across the site, with the strongest component of flow to the southeast. 3.3 GROUNDWATER ANALYTICAL RESULTS 3.3.1 Groundwater Samples TCE and PCE were the only VOC constituents to exceed the ROD Performance Standards in groundwater samples collected during the 2nd Quarter LTRA sampling event. TCE and PCE concentrations were both detected in groundwater sampled from 9 wells, but exceeded the Performance Standard of 2.8 µg/L (TCE) and I µg/L (PCE) in only 5 groundwater samples. TCE exceeded the ROD Performance Standard in the following samples: MW-2 (6.1 µg/L), MW-9 (8.6 µg/L), MW-15 (50 µg/L), MW-17 (13 µg/L), andMW-18 (6.1 µg/L). PCE exceeded the ROD Performance Standard in the following samples: MW-2 (3.7 µg/L), MW-6 (1.2 µg/L), MW-12 (I.I µg/L), MW-17 (5.7 µg/L), and MW-18 (10 µg/L). Laboratory analytical results for first and second quarter L TRA sampling events are summarized in Table 3-3.

Laboratory analytical reports are included in Appendix B. The highest TCE concentration (50 µg/L) was detected in groundwater sampled from monitor well MW-15, located at the west central portion of the site. This well was not sampled during the first quarter sampling event. The second highest TCE concentration (13 µg/L) was detected in groundwater collected from monitor well MW-17, located at the far southeastern corner of the site, adjacent to Blackwood Creek. The TCE concentration increased slightly (by 1 µg/L) from the first quarter sampling event. The highest PCE concentration (10 µg/L) was detected in groundwater sampled from MW-18, also located near the southeast corner of the site. This concentration is also slightly higher (by 1 .4 µ g/L) than that detected in groundwater sampled from this well during the first quarter sampling event. TCE concentrations decreased from levels detected in the first quarter sampling event in three locations (MW-6, MW-9, and MW-12, located in the central portion of the site) and increased in 5 locations (MW-2, MW-5, MW-IO, MW-17, and MW-18). Two of these latter wells (MW-5 and MW-10) are located at the northwestern upgradient edge of the plume. The remaining three are located downgradient of the plume center at the southern and eastern portion of the site. PCE concentrations decreased from levels detected in the first quarter sampling event in two locations (MW-6 and MW-12, located in the central portion of the site) and increased in 5 locations (MW- 2, MW-3, MW-9, MW-10, and MW-18). Two of these latter wells (MW-3 and MW-10) are located at the northwestern upgradient portion of the site, and MW-9 is located in the central portion of the site. The remaining two are located at the southeastern downgradient portion of the site.

Following sampling activities the drum was sampled for voe analysis to determine proper disposal. The analytical results for the purge water sample are summarized in Table 3-1. The purge water results indicate levels of constituents not representative of site contaminants (i.e., ethlybenzene, xylenes, toluene). The purge water sample from the first quarter sampling event had contained no voes exceeding the state or federal drinking water standards and was discharged to the ground during the second groundwater sampling event field activities. Because the containment drum had been stored at a residence between sampling events, and was not secured against tampering, it is likely the drum had been used previously to store materials containing contaminants reported in the purge water analytical results. The drum contents, profiled as non-hazardous, will be transported and disposed appropriately.

SECTION 4 Second Quarter Sampling Event Report Davis Park Road TCE Site Section: 4 Revision: O Date: January 2003 CONCLUSIONS AND RECOMMENDATIONS 4.1 LTRA RESULTS SUMMARY The source for the TCE/PCE contamination in groundwater at the Davis Park Road TCE Site is depleted or removed based on groundwater sampling results reported from the time of contaminant discovery (I 990) to the current LTRA second quarter sampling event in September 2002. Water sampled from wells north of Skyland Drive and in the Cedar Oak Circle Subdivision contained concentrations of between 44 and 134 µg/L TCE and up to 24 µg/L PCE when sampled in 1990. Water sampled from these same wells did not contain concentrations of TCE or PCE at concentrations greater than the ROD remedial groundwater clean-up goals of 2.8 µg/L and 1 µg/L, respectively. Although TCE and PCE concentrations in some wells located south and west of the source area have increased, contaminant concentrations are significantly lower than those detected in the source area at the time of the initial discovery in all but one well location. Groundwater sampled from monitor well MW-15, located southwest of the source area, contained 50 µg/L TCE during the current sampling event. Excluding this groundwater sample, the maximum TCE concentration for groundwater samples collected during the second quarter LTRA sampling event is 13 µg/L in groundwater sampled from well MW-17, and the maximum PCE concentration (including the sample for MW-15) is 10 µg/L in groundwater sampled from well MW-18. Both wells MW-17 and MW-18 are located on the south and southeast portion of the site approaching Blackwood Creek, suggesting groundwater contamination continues to attenuate as it migrates toward this natural groundwater discharge area.

Second Quarter Sampling Event Report Davis Park Road TCE Sile Section: 4 Revision: O Date: January 2003 Concurrently with the migration toward Blackwood Creek, there appears to be contaminant migration southwest of the source area. Although pumping of groundwater has been discontinued over most of the Davis Park Road TCE site area, two community wells (MW-I 0 and MW-I I) are currently still active near Briar Oak Drive, west of the site. Community well MW-I 0, located on Skyland Drive, supplies between 30 and 40 people, and MW-11, located on Briar Oak Drive, supplies approximately nine people, according to Mr. Doc Thompson of the Gaston County Health Department. Pumping of these wells may facilitate migration of groundwater contaminants in a westerly direction. Monitor well MW-15 is located southwest of the source area, with Davis Park Road to the east and well MW-9 to the southwest. TCE was detected at a concentration of 34 µg/L in groundwater sampled from this well in February 1998 and at a concentration of 50 µg/L in groundwater sampled during the second quarter LTRA sampling event. These concentrations are similar to previous levels detected in groundwater sampled from converted community well MW-12 (located east and downgradient of the source area). TCE concentrations fluctuated between approximately 30 and 50 µg/L in groundwater sampled from MW-12 from 1990 through 1998. TCE was detected at 2.3 µg/L in groundwater sampled from MW-12 during this groundwater sampling event. TCE concentrations in groundwater sampled from well MW-9 ( currently supplied with a carbon filtration unit) have fluctuated since August 2000 when first sampled, but have ranged from 6.8 µg/L ( detected in November 2001) to 14 µg/L (detected in April 2002). These levels are similar to groundwater samples collected from wells MW-18, located further south and downgradient of the source area toward Blackwood Creek. 4.2 CONCLUSIONS TCE and PCE concentrations continue to decrease in the contaminant plume as it migrates south and away from the source area. Additionally, no additional degradation products of these two constituents were detected at any significant level in any of the groundwater samples collected K:120064 \ 138\Quarterty\secondquarterreport2. doc 4-2 I I I I I I I I I I I I I I I I I I I This document was prepared by Weston Solutions, Inc., expressly for EPA.

Second Quarter Sampling Event Report Davis Part< Road TCE Site Section: 4 Revision: 0 Date: January 2003 historically or during the LTRA quarterly sampling events. These findings support the groundwater concept model (EPA Memorandum25 September 2000) that the primary mechanism for the observed natural attenuation of the TCE plume at Davis Park Road is dilution as contamination essentially flushes through the bedrock aquifer. The analytical results are consistent with the proposed cleanup time of 14 years (by the year 2017) to attain EPA MCLs. In conclusion, the Second Quarter LTRA sampling event results confirmed that natural attenuation is occurring at rates according to expectations, no changing conditions have arisen that might reduce efficacy of this remedy, no toxic and/or mobile transformation products are being produced, the plume is not expanding, there is no impact downgradient, there 1s no evidence of a new release, and source area wells have attained remediation objectives. 4.3 RECOMMENDATIONS Quarterly sampling of the 18-well network should continue for one year to confirm findings of the first and second quarters, and to monitor further migration of the plume west toward the currently active community wells.
