As concerns over water quality continue to grow, the Environmental Protection Agency (EPA) has just released critical new data on PFAS contamination in U.S. drinking water. On August 14, 2025, the EPA unveiled the ninth round of results from its Fifth Unregulated Contaminant Monitoring Rule (UCMR 5), highlighting the ongoing crisis of these "forever chemicals." At Tradewinds Water, we're committed to helping families and businesses access clean, safe water, and this update underscores the urgency of proactive solutions like advanced filtration systems.
In this blog post, we'll break down the latest findings, explain what PFAS are, discuss health implications, and share practical steps to protect your water supply. Whether you're a homeowner checking your local tap or a business owner ensuring compliance, staying informed is the first step toward safer water.
What Are PFAS and Why Do They Matter?
PFAS, or per- and polyfluoroalkyl substances, are a group of man-made chemicals used in products like non-stick cookware, waterproof clothing, and firefighting foams. Dubbed "forever chemicals" because they don't break down in the environment, PFAS can accumulate in the body over time, leading to serious health risks.
Key facts about PFAS:
- Persistence: They remain in soil, water, and air for decades or longer.
- Health Risks: Exposure is linked to cancer, immune system suppression, thyroid issues, and developmental problems in children.
- Sources: Common contamination comes from industrial sites, military bases, and consumer products leaching into groundwater.
Key Findings from the EPA's Ninth Round of UCMR 5 Data
Here's a summary of the alarming statistics:

Details
|
|---|---|
|
Sites with Detectable PFAS
|
3,309 new sites identified in this round, bringing the national total to 9,552 across all 50 states, the District of Columbia, and four territories.
|
|
Affected Population
|
An estimated 172 million people are served by water systems testing positive for PFAS, based on combined UCMR data and other sources.
|
|
Types of PFAS Detected
|
Focus on PFOA, PFOS, and other regulated compounds; maximum concentrations are tracked, with totals reflecting all PFAS at sampling points.
|
|
Notable Trends
|
Military installations show detections above EPA standards, potentially exposing service members and families. Overall, the data likely underestimates exposure, as a 2020 study suggested over 200 million Americans may have PFAS at lower levels (1 ppt or higher).

These numbers reveal a growing crisis, with contamination spreading from industrial hubs to rural areas. The Environmental Working Group's (EWG) interactive map, updated with this data, allows users to search by ZIP code for local insights.
Health and Environmental Implications of PFAS Contamination
The scale of this contamination is staggering, but the real concern lies in its long-term effects. PFAS bioaccumulate, meaning even low-level exposure over time can lead to health issues. Vulnerable groups include pregnant women, infants, and those with compromised immune systems.
Environmentally, PFAS pollute ecosystems, affecting wildlife and agriculture. Rivers, lakes, and groundwater sources are hotspots, often near military bases or manufacturing plants where firefighting foams were used.
Recent EPA moves, like adding 196 PFAS to the Toxics Release Inventory and designating PFOA/PFOS as hazardous under Superfund law, show progress—but lawsuits and delays highlight the need for individual action.
How to Protect Your Family and Home from PFAS
While waiting for nationwide regulations to take full effect, you don't have to rely solely on public systems. At Tradewinds Water, our certified filtration solutions are designed to remove PFAS and other contaminants effectively.Steps you can take today:
- Test Your Water: Use the free Water Quality Search by Zip Code to check for PFAS levels. https://tradewindswater.com/pages/water-report
- Install Advanced Filters: Specifically formulated activated carbon systems certified for PFAS reduction. At Tradewinds Water, we recommend starting with proven, whole-house systems that provide comprehensive protection without compromising water flow or pressure.
- Choose PFAS-Free Products: Opt for cookware and clothing without these chemicals to prevent further contamination.
- Stay Informed: Use tools like the EWG's map to monitor your area and advocate for local cleanups.
Frequently Asked Questions (FAQs) About PFAS and the Latest EPA UpdateWhat is UCMR 5, and why is it important?
UCMR 5 is the EPA's program requiring water systems to test for unregulated contaminants like PFAS. It provides data to inform future regulations and reveals the extent of pollution.
How can I check if my water is contaminated?
The EPA's standards set limits at 4 ppt for PFOA and PFOS, but health experts argue no level is truly safe due to bioaccumulation.
