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