Former Tesoro Terminal - 3 - 14 August 2006 <br /> 1700 South River Road <br /> Yolo County <br /> 3. None of the reports submitted thus far have any tidal data or discussion if tidal <br /> influence may affect the migration of chlorides and TDS at the site. Please provide <br /> tidal data in the next quarterly monitoring report and provide an assessment <br /> regarding any tidal influence on the local groundwater. <br /> 4. Data indicates a clear impact from the brine pit as concentrations are elevated when <br /> compared to B-1 and ship channel water. The chloride and TDS plume will require <br /> further delineation when background levels for chloride and TDS have been <br /> established. <br /> 5. Although levels of chloride and TDS have been decreasing in all monitoring wells <br /> since use of the brine pi�ias stopped, quartefig groundwater monitoring will need to <br /> continue until further notice. <br /> 6. Please be advised that all documents, including work plans, quarterly monitoring <br /> reports, investigation/cleanup reports, etc.; and all analytical and site data must be <br /> electronically uploaded to the State Water Resources Control Board's GeoTracker <br /> database and is due at the time the paper copy is submitted to this office and San <br /> Joaquin County Department of Environmental Health.
