Sampling methodolgies changed to GAA standards as of July 2004 sampling round. 2. This table includes only those compounds detected. 3. RSR criteria means Remedial Standard Regulation criteria established by the Connecticut Department of Environmental Protection (CTDEEP). 4. NE means numeric RSR criteria not established by CTDEEP. 5. ND means that the compound was not detected above laboratory detection limit. 6. Concentrations in bold type exceed criteria established by CTDEEP. 7. ug/L means micrograms per liter; mg/L means milligrams per liter. 8. B: Compound also detected in one or more associated laboratory blanks. Chloromethane reported by laboratory as a likely analytical laboratory artifact. Haley & Aldrich, Inc.
