What Ground Water Remediation Standards are applied at remediation sites?
The Ground Water Remediation Standards that are applied at remediation sites depend upon the ground water classification in which the site is located. The ground waters of the State are divided into three major classes: Class I – Ground Water of Special Ecological Significance Class II – Ground Water for Potable Water Supply Class III – Ground Water with Uses Other than Potable Water Supply For remediation projects located in Class I areas, the Ground Water Remediation Standards are natural quality or “background.” For those constituents that are not naturally occurring (e.g., volatile organic chemicals, pesticides), the Ground Water Remediation Standards are set at the practical quantitation level (PQL). For remediation projects located in Class II areas, the Ground Water Remediation Standards are the higher of the PQL and the health-based ground water quality criterion for a given constituent listed in Appendix Table 1, and the interim generic ground water quality criteria listed in
