The QMR discusses the groundwater monitoring <br /> activities conducted in November 2001 and summarizes the groundwater monitoring results and <br /> remedial activities for 2001. The Report describes the well abandonment,replacement, and <br /> development activities performed in January and February 2002. The Report proposes not to replace <br /> abandoned well MW-17 based on the proximity of three monitoring wells screened in the same <br /> monitoring zone. Equiva was unable to remove the blockage in MW-1, and the permanent steel <br /> structure around the well prevents well abandonment. The Report recommends continuing to extract <br /> from MW-1 because the blockage is in the bottom four feet of the well, adding monitoring wells MW-10 <br /> and MW-15 to the groundwater extraction and treatment system(GWETS), and installing monitoring <br /> well MW-34 now that Equiva has obtained the access agreement. <br /> We concur with the proposed activities and recommendations. Equiva must ensure that extracting from <br /> additional wells does not exceed the flow or effluent limits in National Pollution Discharge Elimination <br /> System General Order No. 5-00-11912. By 31 May 2002, please provide a well installation report. The <br /> next quarterly monitoring report is due by 30 April 2002.
