Wendy L. Cohen -3- 4 January 1994 <br /> 20 June 1989- Another letter from SPPL to RWQCB notes that sampling of Trapper Slough has <br /> been done and that negotiations with the new land owner are still underway. <br /> 1993- Semi-Annual Groundwater Monitoring Reports prepared by Terra Services submitted to the <br /> Board by SFPP. Reports show that water level and free product gauging and well sampling has <br /> occurred twice in 1992 and twice in 1993. The latest report (October 1993) shows free product is <br /> now showing up in the farthest downgradient wells (N8 and N16). The plume has moved farther to <br /> the southeast, and an upgradient well (N-15) now also has free product which means that dispersion <br /> of the plume is occurring northward towards Trapper Slough. <br /> SUMMARY <br /> 1) Well construction information is missing for wells M8-M10, 01 and 02. <br /> 2) No interim remediation is taking place although free product is consistently measured in <br /> several wells. <br /> 3) The lateral extent of ground water contamination is now undefined again due to the long wait <br /> in remediation efforts. <br /> JMW:Idj <br />
