42 U.S. Code § 300j–13 - Source water quality assessment

(a) Source water assessment
(1) Guidance
Within 12 months after August 6, 1996, after notice and comment, the Administrator shall publish guidance for States exercising primary enforcement responsibility for public water systems to carry out directly or through delegation (for the protection and benefit of public water systems and for the support of monitoring flexibility) a source water assessment program within the State’s boundaries. Each State adopting modifications to monitoring requirements pursuant to section 300g–7 (b) of this title shall, prior to adopting such modifications, have an approved source water assessment program under this section and shall carry out the program either directly or through delegation.
(2) Program requirements
A source water assessment program under this subsection shall—
(A) delineate the boundaries of the assessment areas in such State from which one or more public water systems in the State receive supplies of drinking water, using all reasonably available hydrogeologic information on the sources of the supply of drinking water in the State and the water flow, recharge, and discharge and any other reliable information as the State deems necessary to adequately determine such areas; and
(B) identify for contaminants regulated under this subchapter for which monitoring is required under this subchapter (or any unregulated contaminants selected by the State, in its discretion, which the State, for the purposes of this subsection, has determined may present a threat to public health), to the extent practical, the origins within each delineated area of such contaminants to determine the susceptibility of the public water systems in the delineated area to such contaminants.
(3) Approval, implementation, and monitoring relief
A State source water assessment program under this subsection shall be submitted to the Administrator within 18 months after the Administrator’s guidance is issued under this subsection and shall be deemed approved 9 months after the date of such submittal unless the Administrator disapproves the program as provided in section 300h–7 (c) of this title. States shall begin implementation of the program immediately after its approval. The Administrator’s approval of a State program under this subsection shall include a timetable, established in consultation with the State, allowing not more than 2 years for completion after approval of the program. Public water systems seeking monitoring relief in addition to the interim relief provided under section 300g–7 (a) of this title shall be eligible for monitoring relief, consistent with section 300g–7 (b) of this title, upon completion of the assessment in the delineated source water assessment area or areas concerned.
(4) Timetable
The timetable referred to in paragraph (3) shall take into consideration the availability to the State of funds under section 300j–12 of this title (relating to State loan funds) for assessments and other relevant factors. The Administrator may extend any timetable included in a State program approved under paragraph (3) to extend the period for completion by an additional 18 months.
(5) Demonstration project
The Administrator shall, as soon as practicable, conduct a demonstration project, in consultation with other Federal agencies, to demonstrate the most effective and protective means of assessing and protecting source waters serving large metropolitan areas and located on Federal lands.
(6) Use of other programs
To avoid duplication and to encourage efficiency, the program under this section may make use of any of the following:
(A) Vulnerability assessments, sanitary surveys, and monitoring programs.
(B) Delineations or assessments of ground water sources under a State wellhead protection program developed pursuant to this section.
(C) Delineations or assessments of surface or ground water sources under a State pesticide management plan developed pursuant to the Pesticide and Ground Water State Management Plan Regulation (subparts I and J of part 152 of title 40, Code of Federal Regulations), promulgated under section 136a (d) of title 7.
(D) Delineations or assessments of surface water sources under a State watershed initiative or to satisfy the watershed criterion for determining if filtration is required under the Surface Water Treatment Rule (section 141.70 of title 40, Code of Federal Regulations).
(E) Delineations or assessments of surface or ground water sources under programs or plans pursuant to the Federal Water Pollution Control Act [33 U.S.C. 1251 et seq.].
(7) Public availability
The State shall make the results of the source water assessments conducted under this subsection available to the public.
(b) Approval and disapproval
For provisions relating to program approval and disapproval, see section 300h–7 (c) of this title.
