Why we exist
U.S. drinking water is some of the most heavily regulated water on the planet. It is also imperfect, and the gap between "in compliance" and "safe to drink without thinking about it" is wider than most people realize. The Safe Drinking Water Act covers about 90 contaminants. EPA's Contaminant Candidate List names hundreds more that may need regulation. Until 2024, none of the PFAS class was federally regulated at all.
For a long time, the two main public sources of information about U.S. tap water have been (a) your utility's annual Consumer Confidence Report — a procedural document, not a health-protective one — and (b) consumer advocacy groups whose mission is often to mobilize concern rather than to give a balanced read.
We sit in between. We take regulatory data seriously, including its limits. We take the advocacy critiques seriously, including their limits. We try to tell readers what the evidence shows — and where it doesn't show anything yet.
What we publish
- Per-ZIP water reports drawn from EWG's Tap Water Database, with contaminant levels measured against EWG's health-protective guidelines and our published methodology.
- Contaminant deep-dives on every substance regulated under the Safe Drinking Water Act, plus the major unregulated contaminants of concern (microplastics, pharmaceuticals, chromium-6).
- Pillar articles on health effects, demographic impact, filtration, and policy — written to be the last thing you need to read on each topic.
- Editorial news coverage when policy or science changes meaningfully — like the 2024 PFAS rule, the 2024 Lead and Copper Rule Improvements, and the 2024 NTP fluoride monograph.
- A free weekly newsletter summarizing all of the above.
How we're funded
The Water Awareness Initiative is an educational program operated and funded by Poseidon Solutions, LLC, a U.S. water services company. We disclose that upfront because trust in water reporting depends on knowing who pays for it.
Poseidon Solutions funds site development, hosting, editorial payroll, and operations. We also accept individual donations and unrestricted philanthropic grants from foundations and family offices interested in public-health literacy.
Editorial firewall. Poseidon Solutions, LLC does not review, edit, approve, or veto any article, report, or score published on this site. The editorial team operates under a written firewall: no funder — including the parent — has copy approval. If that ever changes, this page changes first.
What you will not see on this site. No advertising. No affiliate links. No filter referrals. No sponsored content. No e-commerce. We are not paid per click, per signup, or per filter sold by anyone — including Poseidon.
We will publish an annual transparency report listing donors above a low threshold and any material changes to the editorial firewall. The first such report will appear at the end of our first full fiscal year.
How we work
Every numeric claim, regulatory limit, and health effect cited on the site traces back to a primary source. Our citation registry lives at /methodology. If we can't cite a primary source, we don't print the claim. "Studies show" doesn't count.
Articles are dated. Articles are also updated when the science or regulation moves; the update date is published openly. We do not silently edit articles to make older predictions look better.
Where the science is genuinely uncertain, we say so. The honest answer to a lot of water-health questions in 2026 is "the association is real but the magnitude is debated" or "the mechanism is plausible but the human data is thin." We try to mark those questions clearly rather than papering over them with confident language.
Corrections
If you spot an error — a misquoted limit, a stale citation, a misleading framing — write to corrections@waterawarenessinitiative.com. We publish every correction we make at /methodology#corrections with the original wording, the corrected wording, and the date.
Who we are
The Water Awareness Initiative launched in 2026 as the educational arm of Poseidon Solutions, LLC. Our editorial team includes researchers, public-health practitioners, and writers with backgrounds in environmental health, water engineering, and science journalism. We are deliberately opaque about individual identities for the early period of the initiative's existence — partly because we want the work to be judged on its merits, and partly because environmental-health reporting attracts more lawsuits than most journalism. We will name our team publicly when we are confident we can do so without chilling honest reporting.
What we are not
We are not a substitute for a certified laboratory test of your own tap. We are not a regulatory agency. We are not a litigation source. We will not tell you which filter to buy. We will tell you which certifications matter, and we will be honest about the limits of our own analysis.
