4/8/2003 |
Update or Other Action |
DEC received the "Groundwater Monitoring and Well Installation - October/November 2002, Former Aqua System #1" report from Tetra Tech. Groundwater samples collected during November 2002 did not contain petroleum at levels above the proposed groundwater cleanup levels (based on the ten times rule and a determination that groundwater beneath the area is not a current or likely future drinking water source) and the downgradient wells did not contain elevated contaminant levels that would indicate a contaminant discharge into surface waters. Semiannual (spring/fall) sampling was recommended for another year. |
