Where to Learn Drinking Water Basics on the EPA Website

Updated

The U.S. Environmental Protection Agency (EPA) hosts a Drinking Water Resources section on epa.gov that explains how water reaches a household tap, describes the different types of public water systems, and provides basic information about drinking water safety. It is a general-audience resource, not a lookup tool for your specific address — for local results you still need your water utility's own reports.

What the Drinking Water Resources section covers

According to the EPA homepage, the section is framed around three questions:

  • How water gets to your tap — the path from source water through treatment and distribution to the household.
  • Types of public water systems — the categories EPA uses to classify community and non-community systems.
  • Drinking water safety basics — foundational information on what safety means for public supply.

The homepage links to this content under the label "Drinking Water Resources" with the prompt to "Explore drinking water resources."

How to reach it

  1. Go to epa.gov.
  2. Locate the "Drinking Water Resources" link in the homepage's featured resource area.
  3. Follow it to the drinking water topic pages.

Expected result: a set of explainer pages written for the general public rather than regulatory text. If you land on a page dense with rule citations, you are likely in the regulatory or rulemaking area rather than the basics section — use the site's topic navigation to return to the introductory material.

What else on the homepage is relevant

The EPA homepage also surfaces related items that help you interpret drinking water news:

Homepage item Why it matters for drinking water
PFAS funding and proposed rules announcement Nearly $1 billion in new state funding to address PFAS in drinking water, plus two proposed rules for public comment upholding National Primary Drinking Water Standards for PFOA and PFOS
News releases Site-specific cleanup and water announcements, e.g., Chesapeake Bay watershed restoration funding and Superfund groundwater cleanup plans
"Send a Request for Technical Support" Channel to ask a question, provide feedback, or report a problem

The PFAS item is the clearest example of how the site connects a contaminant topic to both funding and rulemaking. If your question is specifically about PFAS rather than general drinking water basics, start with that announcement and follow its "Learn about efforts to reduce PFAS" link.

Limits to keep in mind

  • The basics pages explain systems and concepts; they do not tell you what is in your own water. That information comes from your utility's consumer confidence report.
  • The homepage notes a "Last updated on August 6, 2026" date, so check page-level dates on individual resources before relying on them for current figures.
  • The site lists a "subscribe" option, but the homepage does not state terms, pricing, or login requirements for any service — do not assume access conditions either way.

A practical sequence

If you are starting from zero: read the "how water gets to your tap" page first, then the public water system types page, then the safety basics. That order matches how the content is structured and lets you place later news items — such as the PFAS funding announcement — in context.
