<br /> Dear Mr. Church:
<br /> The San Joaquin County Environmental Health Department (EHD) has reviewed
<br /> Groundwater Monitoring Report— Fourth Quarter 2009, dated February 24, 2010, prepared
<br /> and submitted by Advanced GeoEnvironmental, Inc. (AGE) on your behalf for the above-
<br /> referenced site. Based on the analytical results from the monitoring and sampling event on
<br /> December 16, 2009, AGE has recommended that monitoring wells MW-1, MW-4, and MW-7
<br /> be sampled during the second quarter 2010. The EHD concurs with this recommendation
<br /> and directs that these three wells be sampled semi-annually. Biennially collect groundwater
<br /> samples from the remaining wells: MW-2, MW-3, MW-5, MW-6 (upper), and MW-6 (lower).
<br /> Analyze groundwater samples for total petroleum hydrocarbons quantified as gasoline
<br /> (TPH-g); benzene, toluene, ethylbenzene, and total xylenes (BTEX); and 1,2-dichloroethane
<br /> (1,2-DCA) and omit the analysis for methyl tertiary-butyl ether (MTBE).
<br /> If you have any questions concerning this letter, please contact Vicki McCartney at (209)
<br /> 468-9852, or by email at vmccartney@sjcehd.com.
<br /> Sincerely,
<br /> &gA
