QUARTERLY GROUND WATER MONITORING <br /> Wells MW-1 through. 1K1W-3 were initially sampled for TPH-g on 13 August 1987 by Weiss <br />' Associates. The wells were again sampled on 8 September 1987 for BTE&X. No further sampling <br /> was performed between 1987 and October 1992. <br /> Between October 1992 and January 1995, monitoring at the site has been performed on eight <br /> occasions. Petroleum hydrocarbon concentrations have fluctuated in most wells over that period. <br /> Past and current analytical results of ground water samples are included in Table 2. <br /> 2.4. SOEL AND GROUND WATER REMEDIATION <br /> Inpreparation for soil remediation at the site boring RW-1 was installed in August 1993 b <br /> g � Y <br />' GeoAudit. This boring was drilled at a 15° angle from vertical from a surface location near the <br /> southeast corner of the building, and completed as a 4-inch diameter remediation well. A Final <br /> Remedial Plan(FRP)was then prepared by GeoAudit in July 1994, outlining soil and ground water <br /> remediation procedures for the site. Implementation of the FRP was delayed because of access <br /> difficulties with the owner of the neighboring property, which is currently operated as an A& W <br /> restaurant. However, access permission was obtained in March 1995 and remediation installation <br /> procedures have been initiated by AGE. <br />' 3.0. PROCEDURES <br /> 3.1. MONITORING WELL PURGE PROCEDURES <br />' On 27 A.pri127 1995, the ground water depth was measured in each well using a Solinst water level <br /> meter. After depth measurements were collected, PVC bailers were used in an attempt to removed <br /> t three well volumes from each well except MW-2 (MW-2 was not purged or sampled). Because of <br /> poor recharge, three well volumes could not be removed from MW-1 nor MW-3- Ground water <br /> stabilization parameters were measured at one-gallon intervals using an ICM water analyzer; <br />' stabilization parameters were measured at three-gallon intervals for MW-1. Purged water was stored <br /> on-site in 55-gallon drums. Field data sheets are included in Appendix A. <br /> - - 3:2: -- GROUND WATER SAMPLE-COLLECTION <br />' Water samples were collected from MW-1, MW-3, MW-4, MW-5, MW-6, MW-7 and MW-8 using <br /> new disposable plastic bailers. The samples were collected in 40-m1 EPA vials, placed in a chilled <br /> 1 <br />
