<br /> In response to your request dated June 25, 2009 to reduce the monitoring well sampling
<br /> frequency and to comply with the State Water Resources Control Board (SWRCB) Resolution
<br /> #2009-0042 dated May 19, 2009, the San Joaquin County Environmental Health Department
<br /> (EHD) has reviewed the ground water analytical data collected to date for the above subject site
<br /> and approves the following sampling and testing modifications:
<br /> 1. Semi-annual sampling of monitoring wells MW-6A, MW-8A and MW-9A and testing for
<br /> total petroleum hydrocarbons as gasoline (TPHg), benzene, toluene, ethyl-benzene, and
<br /> total xylenes (BTEX), and methyl tert-butyl ether (MtBE) each first and third quarter,
<br /> starting July 2009.
<br /> 2. Semi-annual sampling of monitoring wells MW-2 and MW-4 and testing for MtBE, each
<br /> first and third quarter, starting July 2009.
<br /> 3. Annual sampling of monitoring wells MW-613, MW-8B, and MW-9B and testing for TPHg,
<br /> BTEX, and MtBE starting the first quarter of 2010.
<br /> 4. Biennial sampling of monitoring wells MW-3, MW-5, MW-7A, and MW-7B for TPHg,
<br /> BTEX, and MtBE starting the first quarter of 2011.
<br /> 5. Monitoring well MW-10 is the pumping well and is required to be sampled more
<br /> frequently as required by the waste water discharge permit issued by other regulatory
<br /> agencies.
<br /> The remediation status report is still required to be submitted to Geotracker on a quarterly basis
<br /> and is to include an update on the investigative and remedial status of the site, activities
<br /> conducted at the site during the reporting period, and dates when future activities at the site will
<br /> occur.
<br /> You may contact Michael Infurna at (209) 468.3454 if you have any questions.
