Sample results did <br /> not indicate contamination above the laboratory's detection limits. Monitoring well, MW4,was <br /> i not located and is assumed that the well head was paved over. The COS has not been able to <br /> j locate MW4 and continues to evaluate options. <br /> ' By late May 1992, a work plan to investigate the extent of soil contamination will be submitted to <br /> j PHS/EHD. <br /> 1 <br /> j By the June 1992 quarterly sampling, MW4 should be located, and the work proposed in the May <br /> work plan completed.

However, MW4 had approximately 1.5 feet <br /> of free product <br /> ' The free product standing in MW4 will be periodically bailed off and placed in DOT approved <br /> drums. The product recovery rate will be measured to estimate free product volume. <br /> ' A copy of the destruction specifications for the facility well will be submitted to PHS/EHD. <br /> ' Quarterly sampling will occur in June 1992,with the resultant quarterly report to be submitted to <br /> i.
