(AGE) on behalf of Herman &Helen's Marina (H&H Manna) at the Venice Island Ferry in <br /> Stockton. The QMR discusses the groundwater monitoring activities performed in June. We have <br /> no comments on the QMR. The Addendum proposes to drill three borings in the area of the former <br /> underground storage tanks to collect soil and grab groundwater samples and to conduct a pump test <br /> at proposed extraction well EW-1. H&H Marina will advance one of the three borings at a 25- <br /> degree angle to assess the distribution of polluted soil. The work proposed in the Addendum is in <br /> addition to the work proposed in the 14 May 2002 Monitoring Well Installation Work Plan. <br /> We have the following comments on the Addendum: <br /> 1. The collection of grab groundwater samples in the Addendum is not clear. Section 3.3 states <br /> H&H Marina will collect grab groundwater samples from each boring during the boring <br /> process. Section 4.3 states H&H Marina will collect grab groundwater samples from <br /> selected borings from a depth of four feet below the groundwater surface. H&H Manna <br /> needs to specify which borings and clarify how it will collect the grab groundwater samples. <br /> 2. The Addendum proposes analyzing selected soil samples for various geochemical analyses, <br /> but does not specify which borings. H&H Manna needs to submit samples collected at <br /> extraction well EW-1 for the geochemical analyses. <br /> 3. The Addendum proposes to collect a groundwater sample six hours into and at the <br /> conclusion of the pump test. H&H Marina should also collect a sample during the first hour <br /> of the extraction test because this is typically when the highest concentrations are observed <br /> and will provide data to determine concentration trends during the pump test. <br /> California Environmental Protection Agency <br /> CO Recycled Paper <br /> The energy challenge facing Califomia is real.
