PHS/EHD has the following comments for your <br /> consideration. <br /> Two requests were made within the above mentioned report. The fust request is that the sampling of <br /> monitoring wells MW-2, MW-3, MW-5, MW-6 and MW-9 be suspended. The frequency of sampling these <br /> wells, with the exception of MW-9, may be reduced to semi-annually. With regard to MW-9, since access <br /> is obstructed, sampling may be suspended until closure verification. Quarterly measurements of <br /> groundwater elevation should continue for all monitoring wells. <br /> The second request is that monitoring wells MW-11) and MW-1S be decommissioned. The groundwater <br /> gradient has been consistently to the southeast. However, the gradient has been recently reported, after <br /> resurveying, to the northwest. PHS/EHD does not recommend the decommission of these wells at this <br /> time. If a decision is made to retain use of these wells, the sampling frequency of one well may be <br /> reduced to semi-annual and the frequency of the other well may be suspended until closure verification <br /> sampling. <br /> If you have any comments or questions regarding this letter, please contact Mary Meays, REHS, of my <br /> staff at (209) 468-0337. <br /> reg= <br /> .D., M.P.H. <br /> a, RENS, Program anger <br /> Health Division <br /> c: Elizabeth Thayer, CVRWQCB <br /> c: Steve Fumas,WHF Environmental <br /> A Division of San Joaquin County Health raze Services �� <br />
