water systems to such contaminants. [1453] Sec. 132(a)
Time Frame For Assessments:
Assessments are to be completed for all public water systems within 2 years after EPA
approval of the State’s program. EPA may extend this period up to 18 months taking into
account funds made available to the State under the Drinking Water State Revolving
Fund (DWSRF). States shall make the results of the source water assessments available
to the public. [1453] Sec. 132(a)
Use Of Other Authorities:
To avoid duplication, assessments may make use of sanitary surveys, State wellhead
protection programs, pesticide State management plans, State watershed initiatives
including efforts under the Surface Water Treatment Rule, and efforts under the Federal
Water Pollution Control Act (Clean Water Act). [1453] Sec. 132(a)
Assessment Link To Alternative Monitoring:
For a State to tailor alternative monitoring requirements for public water systems under a
new permanent monitoring relief authority (Section 1418), a State must have an EPA
approved source water assessment program. Any public water system seeking alternative
monitoring requirements under a State’s permanent monitoring relief authority must have
a complete source water assessment. [1453] Sec. 132(a)
