1 <br /> RESULTS OF LABORATORY ANALYSES Working To Restore Nature <br /> Water samples collected from wells MW-1, MW-3, and MW4 were analyzed for TPHg, TPHd, <br /> ' and BTEX using modified EPA methods 801518020. These results and cumulative results of <br /> laboratory analyses are summarized in Table 1. The Chain of Custody Record and laboratory <br /> analytical reports are included in Appendix B. <br /> ' Results of thisrY Y samples q uarter's laboratory analyses of water les from wells MW-1, MW-3, and <br /> P <br /> ' MW4 indicate the following: <br /> • Concentrations of BTEX, TPHg, and TPHd were nondetectable in all wells. <br /> CONCLUSIONS <br /> ' Based on the results of this quarterly monitoring and previous work performed at the site, <br /> RESNA concludes that the TPHg, TPHd, and BTEX concentrations in groundwater have <br /> ' decreased or remained the same since the last monitoring episode in June 1994. The <br /> concentrations detected in the wells sampled are consistent with historical patterns. <br /> RECOMMENDATIONS <br /> Based upon the findings and conclusions of this and previous groundwater monitoring episodes, <br /> RESNA recommends continued monitoring and sampling of wells in accordance with the <br /> approved monitoring schedule provided in RESNA's Second Quarter 1994 Monitoring Report <br /> SCHEDULE <br /> The next quarterly monitoring episode is scheduled for December 1994 with the quarterly <br /> monitoring report submitted in January 1995. Routine well maintenance and inspection will be <br /> performed as necessary during site visits. <br /> 5400561QUARTLWQMR19%DRF 3 <br />
