Another consulting firm sampled the well on a quarterly basis, and tested <br />samples for TKN and nitrates. Reports and correspondence in RWQCB files indicate that <br />only trace amounts of nitrogen were detected. Sierra-Pacific sampled the PM Ag Products <br />well (identified as MW-6) on 16 May 1994. Again, the laboratory test results, shown in <br />Table 1 of our Second-Quarter 1994 Monitoring Well Report (2130 West Washington Street), <br />were negative. <br />On behalf of PM Ag Products, Sierra-Pacific herein requests permission to <br />decommission monitoring well MW-6 in accordance with San Joaquin County <br />regulations. PM Ag Products wishes to overbore and grout MW-6. <br />Sincerely, <br />SIERRA-PACIFIC GROUNDWATER CONSULTANTS, INC. <br />Steph n app, CEG-1133 <br />Senior Engineering Geologist <br />cc.
