On a private well? Your state may help you test for PFAS. New Hampshire and parts of New York offer free testing and rebates up to $5,000 for treatment, and other states have their own programs.

We put the details in one guide. Read it and pass it to a neighbor who’s on well water.

Learn what to do if PFAS in well water show up, including free state programs. We cover testing and rebates in five states and options without a program.

You can't see, smell, or taste PFAS in your water — so how would you know it's there?

A nationwide USGS study found PFAS levels in private wells are just as high as public water systems — being out in the country doesn't automatically mean you're in the clear.

The good news? A simple test (and the right whole-home filter) tells you exactly where you stand, and what to do about it.

Curious what's really coming out of your tap? We can help you find out.

Find out how PFAS in well water reach your private well and when to test. Our team explains testing and whole-home filtration for every tap in your home.

Ever wonder what's actually traveling through the soil around your well?

New research out of Yale found that farmland fertilized with biosolids (treated sewage sludge) can carry PFAS — "forever chemicals" — into nearby groundwater, with up to 2.96 million acres of U.S. cropland potentially affected.

Here's the reassuring part: living near a treated field doesn't automatically mean your well is affected. A simple at-home test tells you exactly what's in your water, so you're never left guessing.

Curious what's really in your well water? A test kit gives you real answers, not assumptions.

Learn how PFAS in biosolids move from fertilized farm fields into well water. Our scientists explain what the research shows and how to test your well.

PFAS are measured in parts per trillion, so a clear glass of water tells you nothing at all. Testing is the only reliable way to know what is coming out of your tap.

Our new guide covers what a PFAS test actually measures, why sample collection matters more than most people expect, and how to read results while EPA rules keep shifting. Read the full explainer here.

PFAS water testing reveals contaminants you cannot see, taste, or smell. Learn about sampling methods, EPA tests, and result interpretation.

WEFTEC Day #1 was great. Nice to see so many old friends and make so many new friends.

Come say hi tomorrow. Booth #3061.

NSF/ANSI 53 certification is one of the strongest signals in a market full of vague filtration claims. It is also narrower than most shoppers realize, covering seven PFAS compounds at a 20 ppt combined limit, a limit that was changed in May 2026.

Our latest article breaks down what the standard tests, where it stops, and how shifting EPA rules on MCLs and MCLGs change the way you should read your results. Read the full breakdown here:

NSF 53 PFAS certification verifies filter performance under controlled conditions. Learn what it covers, its limits, and how to compare certified filters.

If you drink from a private well, no agency is checking it for PFAS. That responsibility sits with you, and testing has gotten far simpler and more affordable than it used to be.

Our new article breaks down why wells fall outside federal rules, what raises risk, and how to read your results as EPA standards keep shifting. Read the full guide here:

Private well PFAS testing reveals contaminants public systems may not report. Learn about well risks, testing methods and interpreting results.

PFAS are measured in parts per trillion, which is well past what any test strip can see. The real differences between test kits come down to sampling method, detection limits, and whether the analytics follow recognized EPA methods.

Our latest article breaks down what "lab-grade" should actually mean, plus how to read your results while EPA rules on MCLs and MCLGs keep shifting. Read the full guide here:

A PFAS water test kit provides lab-grade results at parts-per-trillion levels. Compare sampling methods, analyte coverage, and certification needs.

This is what DEXSORB tires on the ground looks like. Big congrats to Brunswick Water Filters for reaching 100 installations of Purefast POE in North Carolina. Brunswick is a force multiplier and valued Cyclopure installer, bringing DEXSORB filters to fight PFAS in North Carolina. There is no fear of Cape Fear or GenX. Brunswick and Wilmington residents look for the Brunswick Water Filter truck in your neighborhood. It will make you happier than the local ice cream truck!

How fun are origin stories, right? Learning the backstory of a hero or superpower? In the case of our Water Test Kit, it began with a Phase 1 SBIR filing in 2017. (The superpower is the ability to look at a water sample and detect part per trillion levels of PFAS … 55 to be exact.) National Institute of Environmental Health Sciences (NIEHS) believed in the vision for an accurate, affordable, and convenient PFAS test procedure for use at home and in the field. Fast forward, today our PFAS Water Test Kit has tested close to 50,000 water samples, and is being used by the federal and state agencies, environmental groups, and households to providing valuable information PFAS contamination levels. Data that is used to install treatment systems and protect health. Celebrating our 10th year with NIEHS!
