- What it does
- The objective of these grants is to provide financial assistance to eligible States and Tribes, those that have Primary Enforcement Responsibility for the Public Water System Supervision (PWSS) Program, for implementation and enforcement of the requirements of the Safe Drinking Water Act that apply to public water systems. In cases where a State or a Tribe does not have a Primary Enforcement Responsibility program, EPA is authorized to use funds that would have otherwise been made available to the State or the Tribe to assist it in direct implementation of the PWSS program. The fundamental goal of the PWSS Program, and the grants, is to ensure that public water systems comply with the National Primary Drinking Water Regulations listed in 40 CFR 141. State drinking water agencies, which have Primary Enforcement Responsibility for the PWSS Program, and Indian Tribes that receive PWSS grants are to use them to ensure that public drinking water systems, of all types, and of all sizes: (1) are currently in compliance with the drinking water regulations and remain in compliance, (2) are working towards and in the process of achieving compliance when these systems are noncompliant, and (3) are preparing for future compliance with any new drinking water regulations that will be taking effect in the current or following year. Furthermore, State drinking water agencies, which have Primary Enforcement Responsibility for the PWSS Program, and Indian Tribes that receive PWSS grants are required to use the funds to update and maintain its PWSS program to comply with the National Primary Drinking Water Regulations Implementation requirements listed in 40 CFR 142 to ensure that the State or Tribal PWSS program is capable of conducting oversight of all public water systems as new drinking water rules, new public water systems, and/or drinking water program requirements become effective.

How to read these numbers
- Committed through this program
Money committed under this assistance listing (its CFDA program), counted in the year each action happened.
- How it's paid
Most programs pay out one way — a grant, or a direct payment to individuals; the flow bar only appears when a program genuinely mixes types.
- Some recipients aren't itemized
For entitlement programs like Social Security and Medicare, the government reports one aggregate instead of naming tens of millions of people, so the recipient roster isn't part of the public record.
- Awards, counted once
An award count is the number of distinct awards with at least one action that year — each counted once, however many times it was amended.
- The colored bars
Every bar on this page splits by how the money moves:
