(Mid-Atlantic) is pleased to present this report summarizing the December 2003 annual groundwater sampling activities conducted at the Honbarrier, Inc. (Honbarrier) facility located at 600 Melynda Road in Charlotte, North Carolina (Drawing 1.1 ). Groundwater sampling was conducted according to the North Carolina Department of Environment and Natural Resources (NCDENR), Division of Water Quality, Groundwater Section correspondence dated May 7, 2002, and titled, Modification of Sampling Plan. As per the revised sampling plan, monitoring wells MW-2, MW-13, and MW-19 will be sampled on an annual basis and the groundwater samples will be analyzed for volatile organic compounds (VO Cs) according to EPA Method 601. In addition, monitoring well MW-7 will be sampled on an annual basis and the groundwater sample will be analyzed for VOCs according to EPA Methods 601 and 602. 2.0 SITE HISTORY Honbarrier provided bulk-hauling services to a variety of industries. The entire site consists of 30 acres, approximately six acres of which were actively used for terminal operations. The terminal operations began in 1969, under the name Central Transport Incorporated. The site had been farmed prior to its purchase. The facility consisted of a terminal office, maintenance garage, truck wash bays, a boiler house for steam production, a wastewater pretreatment system, former waste treatment lagoons, and parking facilities for empty tank trucks. The site included a facility for cleaning the inside of empty tank trucks following delivery of bulk chemicals. Rinse waters that were generated from these washing operations were collected and treated prior to discharge to the Charlotte Mecklenburg Utility District treatment plant in accordance with permit number 0188. Historically, two on-site impoundments were used to treat tank truck rinse waters. During the 1970s and 1980s, site operations resulted in the release of contaminants into the soil and groundwater. Use of the impoundments was terminated in 1985 when a new pretreatment system commenced operation. Closure of the impoundments began in 1991. The impoundments closed as a landfill in 1992 and are capped to meet Resource Conservation and Recovery Act requirements. Drawing 2.1 shows the location of site surface features, the regulated unit (closed landfill), and seven site monitoring wells installed during the contamination assessment process. Monitoring wells MW-9, MW-10, MW-11, MW-12, MW-14, MW-15, and MW-17 were abandoned on May 15, 1999 in compliance with NCDENR's Recommended Site Activities, and are no longer represented on the site map. Terminal operations at the site ceased in approximately 1995 and the property was vacated. Based on field observations made during the December 2002 sampling event, the subject site is currently leased and utilized as a truck storage terminal.

Facility Charlotte, North Carolina 3.0 FIELD ACTIVITIES January 9, 2004 Page2 Mid-Atlantic mobilized to the site on December 3, 2003, to conduct the groundwater sampling activities. The four monitoring wells sampled during the annual event included MW-2, MW-7, MW-13, and MW-19 (Drawing 2.1). Monitoring well MW-6 has been destroyed by apparent mowing activities. Prior to purging the wells of at least three volumes of water (or to dryness) using new disposable bailers, Mid-Atlantic measured the depth to water in each well using a decontaminated electric water level indicator. A new pair of protective, non-reactive gloves was donned at each well prior to collecting water level measurements. The measured depths were subtracted from the casing elevations to determine the groundwater elevation relative to Mean Sea Level. The physical characteristics of the site monitoring wells and groundwater elevation data are summarized in Table 3.1. After purging the wells, water samples were collected from the same bailers used to purge each well and decanted into laboratory-supplied containers. The containers were placed into an ice-filled cooler and transported under chain-of-custody to Pace Analytical Services, Inc. (Pace) of Huntersville, North Carolina. At the laboratory, the four groundwater samples were analyzed for VOCs according to EPA Method 601. The groundwater sample collected from monitoring well MW-7 was also analyzed for VOCs according to EPA Method 602. In addition, groundwater field measurements were collected for pH, electrical conductivity, dissolved oxygen, and temperature (Table 3.2). 4.0 GROUNDWATER FLOW Groundwater flow direction in the surficial aquifer was estimated based on water level data obtained from the monitoring wells on December 3, 2003 (Drawing 2.1 ). Interpretation of the relative water table elevations suggests that groundwater flows generally to the south across the site. This flow direction is consistent with previously interpreted flow determinations. 5.0 ANALYTICAL RESULTS The laboratory analytical results for the groundwater samples collected on December 3, 2003, are contained in Appendix A and summarized in Table 5.1. As summarized, concentrations of cis-1,2-dichloroethene ( cis-1,2-DCE) (95 micrograms per liter (µg/L)), trichloroethene (TCE} (4.4 µg/L), and vinyl chloride (10 µg/L) were detected in the groundwater sample collected from MW-2 which exceeded their respective North Carolina Groundwater Quality Standards (NCGWQS). One additional VOC was detected in the groundwater sample collected from MW-2 in a concentration below its established NCGWQS. M!I?s-*'l~{\t!.TJ~ Environmental Solutions December 2003 Annual Groundwater Monitoring Report Honbarrier, Inc. Facility Charlotte, North Carolina January 9, 2004 Page3 The groundwater sample collected from monitoring well MW-7 revealed the presence of benzene, chlorobenzene, 1,4-dichlorobenzene, cis-1 ,2-DeE, and vinyl chloride in concentrations of 63 µg/L, 510 µg/L, 98 µg/L, 230 µg/L, and 73 µg/L, respectively, which exceeded their respective NeGWQS. One additional voe was detected in the groundwater sample collected from MW-7 in a concentration below its established NeGWQS. eis-1,2-DeE (77 µg/L) and vinyl chloride (17 µg/L) were detected in the groundwater sample collected from monitoring well MW-13 in concentrations which exceeded their respective NeGWQS. Four additional voes were detected in the groundwater sample collected from MW-13 in concentrations below their respective NeGWQS. Vinyl chloride was detected in the groundwater sample collected from monitoring well MW- 19 at a concentration of 3.1 µg/L, which exceeded its established NeGWQS. Two additional voes were detected in the groundwater sample collected from MW-19 in concentrations below their respective NeGWQS. A total VOe concentration map, showing total detectable VOes, is provided as Drawing 5.1. Historical groundwater sample results and a site map showing existing and previously abandoned monitoring wells are presented in Appendix B. 6.0 SUMMARY AND CONCLUSIONS Based on the field and laboratory analytical results, Mid-Atlantic offers the following summary and conclusions. • Shallow groundwater flow is directed toward the south across the site. • The water sample collected from monitoring well MW-2 exhibited concentrations of cis- 1 ,2-DeE, TeE, and vinyl chloride which exceeded their respective NeGWQS. • The groundwater sample collected from monitoring well MW-7 revealed the presence of benzene, chlorobenzene, 1,4-dichlorobenzene, cis-1,2-DeE, and vinyl chloride in concentrations which exceeded their respective NeGWQS. • eis-1 ,2-DeE and vinyl chloride were detected in the groundwater sample collected from monitoring well MW-13 in concentrations which exceeded their respective NeGWQS. • Vinyl chloride was detected in the groundwater sample collected from monitoring well MW-19 at a concentration which exceeded its established NeGWQS. • Total dissolved VO es detected in the groundwater samples collected from the four monitoring wells in December 2003 have increased by 582.9 µg/L since the sampling event conducted in December 2002. In addition, the average static water level across the subject site has increased approximately one foot since December 2002. MP?s-~l~~~T!C[.
