PFAS & well water testing in Los Angeles.
We match you with an ELAP-certified lab (or NSF-certified installer if you need filtration) serving Los Angeles and surrounding California communities. 4% of Los Angeles households are on private wells — and EPA municipal regulations don't apply to them.
- EPA-method testing. Methods 533 / 537.1 at independent ELAP-certified labs.
- Plain-English results.If filtration isn't needed, they tell you.
- Free for homeowners. Partners pay us only when they win your business.
Every test in the network goes to a federally accredited (ELAP) lab using EPA Methods 533 / 537.1. No DIY strips — real lab analysis.
You get a plain-English PDF lab report. If filtration is recommended, the installer sends an itemized written quote separately.
We're paid by labs and installers only when they win your business — never by you. No upsells, no pressure to filter when you don't need to.
When filtration makes sense, network installers fit systems certified specifically to NSF/ANSI 53 + P473 — the only PFAS-tested standards.
Every test goes to an ELAP-certified lab; every installer is WQA-credentialed
How we vet the partners we route to Los Angeles households.
Every lab in the Los Angeles network must hold current ELAP (Environmental Laboratory Accreditation Program) credentials and run samples via EPA Methods 533 or 537.1. Every filtration installer must hold a current WQA Certified Installer (CI) credential plus state licensing and current liability insurance.
PFAS contamination follows industrial, military, and firefighting-foam history more than population density. Whether Los Angelesis a known hotspot or not, the EPA's new federal limit (4 parts per trillion for PFOA and PFOS) takes effect in 2027 — and the only way to know your number is a lab test.
For wells: bacteria, nitrates, and PFAS can all shift seasonally as the aquifer recharges. Annual testing is the CDC recommendation. For city water: utilities have until 2027 to even begin monitoring — most Californiasystems haven't published numbers yet.
One request. One vetted lab or installer. One written quote.
Every test goes to an ELAP-certified lab. Every filter installation matches an NSF/ANSI 53 + P473 certified system.
Four steps. ELAP labs. No filtration unless your water actually needs it.
WellWaterTrust is a matching service, not a lab or filter installer. We connect you with people who do the work — and we vet every partner before they join the network.
