Review of the pre-excavation groundwater data shows that <br /> groundwater monitored in monitoring ,wells nearly down-gradient of the most impacted <br /> monitoring well, MW-21A, was not impacted. Logically, remediation by excavation would be <br /> expected to reduce the impact on groundwater further, therefore the EHD will rescind the <br /> directive to reinstall monitoring wells and will direct preparation of a closure report instead. <br /> Questions or comments should be directed to Lisa Medina at (209) 468-3455 or to Nuel <br /> Henderson at (209) 468-3436. <br /> Sincerely, <br /> Lisa Medina, REH� Nuel Henderson, PG <br /> Senior Registered Environmental Health Engineering Geologist <br /> Specialist <br /> 2012 Five-Year Review Update Response CUF Claim No 1651.doc <br />
