Bames Trucking Site Code : 2506 <br /> 1817 Fresno Ave. <br /> Stockton, CA 95206 <br /> San Joaquin County Public Health Services, Environmental Health Division (PHS/EHD) has completed <br /> review of the "Subsurface Investigation Report" dated November 20, 1997 that was prepared by <br /> Clearwater Group. PHS/EHD has the following comments for your consideration and response. <br /> The report recommends installation of two soil borings with monitoring wells to further assess the lateral <br /> extent of the contamination in the downgradient direction (south and southeast). Prior to this being done, <br /> PHS/EHD requests another sampling of the existing monitoring wells be done with laboratory analysis for <br /> TPHg, TPHd, BTEX and the five oxygenates (MTBE, TAME, DIPE, ETBA and TBA). <br /> Until investigation and cleanup are complete quarterly reports are to be submitted to PHS/EHD and the <br /> Central Valley Regional Water Quality Control Board. Groundwater samples are to be collected from the <br /> monitoring wells quarterly and analyzed for the above contaminants. The results of the groundwater <br /> samples as well as the information recommended in the Tri-Regional Guidelines are to be contained in the <br /> quarterly-reports <br /> If you have any questions, please do not hesitate to contact me at (209) 468-0337. <br /> Donna Heran, RENS, Director <br /> Environmental Health Division <br /> `�1�t� <br /> Lori Duncan, REHS Margaret L goREHS <br /> Site Mitigation Unit Supervisor <br /> cc: Pat Anderson, Central Valley Regional Water Quality Control Board <br /> cc: Martin Clark, State Water Resources Control Board, Cleanup Fund Unit <br /> cc: Doug Guenther, Clearwater Group, 520 Third Street, Suite 104, Oakland CA 94607 <br /> A Division of San Joaquin Counry Hcalth Care Scrvicas <br />
