(a)  The corporation shall be committed to completion of appropriate studies of the ground and surface water under and adjacent to the central landfill to determine whether and to what extent contamination from the central landfill may affect water quality or public health, and to what extent any contamination has a significant impact on human health or the environment. This requirement may be satisfied in part or in full by studies already underway and in compliance with the Comprehensive Environmental Response, Compensation and Liability Act of 1980, 42 U.S.C., § 9601 et seq. (“CERCLA”) or other applicable federal or state environmental statutes.

(b)  If the studies determine that there is in fact an impact by the landfill on water quality or public health, which is not remediated by the installation of public water, then the corporation shall be responsible to take additional remedial action required to further protect public health or to preserve important environmental qualities which are determined to be threatened. As in the case of studies, this requirement may be satisfied in whole or in part by remedial actions required under CERCLA or other applicable federal or state environmental statutes.
