The Report discusses the soil analytical results and the <br /> installation of six monitoring wells and one extraction well. The QMR discusses the <br /> groundwater monitoring activities conducted in September. <br /> We have the following comments on the Report: <br /> 1. The monitoring well development described in the Report is insufficient. H&H Marina <br /> needs to swab the well and remove a sufficient number of well casing volumes to ensure <br /> any water introduced during the well construction activities is removed and the <br /> developing activities promote good conductivity with the surrounding formation. <br /> 2. The Report does not include any groundwater monitoring data. Without the groundwater <br /> monitoring data, Board staff is unable to evaluate whether the extent of pollution is <br /> defined. H&H Marina needs to include groundwater analytical data with well installation <br /> reports. <br /> 3. The Report states the vertical extent of soil contamination has been defined. Based on the <br /> information provided in the Report, Board staff does not concur with this conclusion. <br /> Results from boring MW-6 show an increase in concentrations from the 50 to 55-foot <br /> depth sample and only one non-detect sample below the 55-foot sample. Monitoring well <br /> MW-6 is screened from 50 to 60 feet below ground surface and groundwater samples <br /> from this well may provide the information needed to determine whether additional depth <br /> delineation soil sampling is needed. <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br /> The energy challenge facing California is real.
