"What's REALLY in your water — and what to do about it."

Consumer-facing PFAS ("forever chemicals") drinking water intelligence — zip-code-level contamination reports, utility accountability grades, water filter matchmaking, regulatory rollback tracking, and data journalism that translates EPA's raw science into actionable, beautiful, location-specific content.

Niche Explored

PFAS (“forever chemicals”) contamination in drinking water — consumer-facing intelligence with zip-code-level lookup, filter recommendations, utility accountability scorecards, and regulatory rollback tracking.

Why This Niche NOW

176 million Americans now known to drink PFAS-contaminated water (EWG March 2026 report)
Trump EPA rolling back drinking water limits in 2026 — massive public fear & information vacuum
EPA’s UCMR 5 data released January 2026 — the most comprehensive PFAS testing ever done on US public water systems
“PFAS in my water” and “forever chemicals drinking water” are exploding search terms
Water filter market is booming — high-commission affiliate opportunity ($200-$600 products, 8-15% commission)
Parents, homeowners, health-conscious consumers are desperate for trustworthy, location-specific info
Most existing content is either too technical (EPA reports) or too clickbaity (health blogs) — massive gap for authoritative, data-driven, location-specific content

Existing Competition

EWG Tap Water Database (ewg.org/tapwater) — the gold standard, but overwhelming, not narrative-driven, no personality. Non-profit. Shows opportunity for a more engaging, opinionated voice
USA Today PFAS Map (data.usatoday.com) — one-time project, not continuously updated, no depth
PlainWater (plainwaterdata.com) — pulls SDWIS data, but very basic visualization, no editorial content
NonToxicLab (nontoxiclab.com) — affiliate blog with PFAS filter reviews, good but manual, not data-driven
TapWaterData (tapwaterdata.com) — generic contaminant guide, not PFAS-focused
PFAS Risk Map (pfasrisk.org) — academic/research tool, not consumer-friendly
ContamiNation Substack (Marina Schauffler) — individual writer, small audience, manual publishing
Gap: No one is combining EPA’s bulk data + USGS water quality + EWG research into automated, continuously updated, consumer-friendly, location-specific content with beautiful design and a distinctive voice

SEO Analysis

“PFAS in my water” — high volume, low-to-medium competition (mostly news articles, not tools)
“forever chemicals drinking water” — exploding search term, USA Today ranking #1 with basic map
“best water filter for PFAS” — high commercial intent, dominated by affiliate blogs
“[city name] water quality PFAS” — long-tail goldmine, thousands of city-specific pages to rank for
“UCMR 5 results” — technical audience, low competition
“is my tap water safe from PFAS” — question-intent keywords, perfect for FAQ content
Keyword gap: City-specific PFAS content barely exists. “Austin PFAS water”, “Chicago PFAS drinking water” — these get searched but have weak results
Programmatic SEO potential: Auto-generate pages for every US water system (10,000+), each optimized for “[city] PFAS water quality report”

Communities
