All eight samples were analyzed for the presence of TPHGas and BTEX constituents. <br /> With one minor exception,all samples were non-detect for each analyte. The shallowest sample(4.3 flogs) <br /> from well MW-12 detected 3.5 ppm of an unidentified hydrocarbon within the TPHGas range. <br /> Each well has been surveyed,developed,and has been incorporated into the existing groundwater <br /> monitoring program for the subject site. <br /> If you have any questions or comments, I can be reached at(510)842-8695. <br /> Sincerely, <br /> 41 <br /> Brett L.Hunter <br /> Environmental Engineer <br /> Site Assessment and Remediation <br /> Attachment <br /> cc: Gordon Boggs, Central Valley RWQCB, Sacramento, CA <br /> Ron Berberian, 2021 W.
