PFAS in Wyoming

PFAS in Wyoming’s drinking water

When PFAS enter drinking water sources, the potential harm extends across entire communities. In Wyoming, officials are monitoring wells, municipal water systems, and surface water to gauge the severity of PFAS contamination. I have observed this issue grow in urgency because public health experts say that even small amounts of PFAS can accumulate in people’s bodies over time.

Known contaminated water systems

Several public water systems in the state have reported PFAS detections. Investigations often center on areas near industrial activities, airports, or military sites. For instance, the Jackson Hole Airport Board joined a lawsuit in June 2024, alleging manufacturers of firefighting foam containing PFAS contributed to local water contamination. This consolidated case involves over 1,200 plaintiffs nationwide, indicating a widespread concern about PFAS in drinking water.

The F.E. Warren Air Force Base in southeastern Wyoming is monitoring PFAS as part of a Department of Defense initiative to assess contamination at military facilities. While data remain under review, historical usage of firefighting foam at these sites suggests possible groundwater migration of PFAS.

Common PFAS sources: AFFF foam, waste facilities, industry

I have come to recognize three major PFAS pathways in Wyoming:

1. AFFF Foam: Often used at airports and military bases to douse fuel fires.

2. Waste Facilities: Landfills and other waste sites that disposed of PFAS-rich materials without special handling in past decades.

3. Industrial Plants: Refineries or chemical operations that once used PFAS for processing or packaging.

These pathways clarify why PFAS turn up in wells, streams, or city water systems, despite the state’s generally low population density.

Water testing efforts by Wyoming DEQ and EPA

The Wyoming DEQ works with the EPA to sample water sources, aiming to identify areas of elevated PFAS. The EPA has set new Maximum Contaminant Levels (MCLs) for certain PFAS, proposing 4 ppt for PFOA and 4 ppt for PFOS. Public water systems will need to comply with these standards by April 2029. In Wyoming, some local authorities have already advised residents to use filters or bottled water when PFAS levels exceed federal or state guidance.

PFAS in Wyoming’s soil and agriculture

While water contamination draws the most attention, PFAS also infiltrate soil. Agricultural lands might be exposed when biosolids or sewage sludge, containing PFAS, are applied as fertilizer. These chemicals can then move from the soil into crops or livestock.

Agricultural risks: Sludge application, crop exposure

I have read data showing that even small amounts of PFAS in sludge or soil amendments can lead to measurable levels of contamination in plants. Because Wyoming has agricultural regions that sometimes use treated sludge for soil enrichment, the risk arises that PFAS could accumulate in corn, wheat, or alfalfa. Continued application over multiple growing seasons might allow these chemicals to build up.

Livestock and groundwater impacts

Livestock can ingest PFAS-contaminated water or feed and then store the chemicals in their tissues. Dairy and beef cattle near industrial or military sites, for instance, might develop PFAS levels that could be passed along in meat or milk. Rural residents who depend on private wells for household water also remain vulnerable. Although the Wyoming DEQ and EPA have begun outreach campaigns, complete data on PFAS in rural wells are still limited.

Health effects of PFAS exposure

I have reviewed multiple studies linking PFAS to adverse health outcomes. The CDC released an update on January 26, 2024, stating there is mounting evidence connecting higher PFAS exposure to an increased risk of kidney cancer. Other documented effects include testicular cancer, thyroid disease, liver disorders, fertility problems, and some autoimmune conditions.

Researchers propose several mechanisms. PFAS may mimic or interfere with hormonal pathways. They might also stress kidney and liver function, as these organs work to filter toxins. Because PFAS persist in the body for years, low-level exposure repeated over time can lead to accumulation. Here are some documented health effects:

• Kidney cancer, particularly among older adults.

• Testicular cancer, with some studies suggesting a direct correlation to firefighting activities or proximity to PFAS industrial sites.

• Thyroid dysfunction, including hypothyroidism.

• Liver damage, indicated by elevated liver enzymes.

• Possible immune system impairment, leading to decreased vaccine response or other autoimmune risks.

Diseases linked to PFAS in Wyoming

Several diseases receive special attention when discussing PFAS in Wyoming. These include cancers of the kidney, testicles, and liver, alongside disorders of the thyroid. I have also noted a growing dialogue around fertility issues and pregnancy complications. Understanding these risks is vital for anyone living near high-PFAS areas.

Testicular and kidney cancer

Research published over the last decade underscores a statistically significant association between PFAS exposure and testicular cancer. A concern in Wyoming centers on firefighting foam usage, particularly around F.E. Warren Air Force Base and local airports. The CDC’s January 2024 health alert also focused on kidney cancer, stating that increased cases in men and women aged 55 to 74 may reflect chronic exposure to PFAS-contaminated drinking water supplies.

Liver and thyroid disorders

I have encountered data showing that Wyoming has seen an uptick in liver cancer diagnoses, which could be tied to PFAS presence near industrial sites. Additionally, PFAS can disrupt thyroid hormone homeostasis, sometimes resulting in hypothyroidism or other thyroid-related conditions. Continuous monitoring by the Wyoming DEQ, along with county health departments, may help determine if any surge in thyroid disorders correlates directly with PFAS.

Fertility and pregnancy complications

Evidence suggests PFAS may affect fertility, potentially leading to lower birth weights or complications during pregnancy. Scientists propose that PFAS might disrupt endocrine signals, which in turn can affect reproductive functions. While comprehensive state-level data are still in progress, pregnant individuals in areas of known contamination may want to consult healthcare providers about PFAS exposure risks.

Autoimmune and developmental conditions

Studies have explored possible associations between PFAS and autoimmune conditions such as ulcerative colitis. In Wyoming, local health departments and research groups watch for trends in autoimmune and developmental disorders, especially among children exposed to PFAS early in life. Although the overall data remain evolving, caution is advised whenever PFAS levels in water or soil surpass proposed guidelines.

How is Wyoming responding to PFAS contamination?

Wyoming authorities are working to balance local economic interests, such as agriculture and industry, with the urgent need to manage PFAS risks. The state is pursuing multiple strategies, including expanded sampling, improved public outreach, and collaboration with national agencies like the EPA.

Government testing initiatives

The Wyoming DEQ began increasing its PFAS testing in 2022, sometimes partnering with the EPA to inspect municipal systems and private wells near probable contamination sources. Officials indicated plans to adopt future federal PFAS rules fully once the EPA finalizes national standards in the coming years.

Public notifications and community response

Public meetings, fact sheets, and local news alerts have kept residents aware of ongoing sampling results. In Jackson Hole, for example, the decision to join an ongoing lawsuit gained wide media coverage. Community health forums regularly gather input from residents concerned about PFAS in drinking water and farmland. In my view, this public involvement drives accountability among commercial and government entities.

Federal and state collaboration

Agencies such as the EPA, the Department of Defense, and the U.S. Department of Agriculture (USDA) contribute resources or technical assistance. The EPA’s PFAS Roadmap, updated periodically, outlines upcoming regulations that Wyoming must follow. This plan includes investigating discharges from industrial facilities into publicly owned treatment works (POTWs) through nationwide data collection, which can help pinpoint the biggest contributors to PFAS in wastewater.

Can you test your water or soil for PFAS in Wyoming?

I often receive questions on how to confirm the presence of PFAS. The Wyoming DEQ suggests using professional laboratories certified to analyze PFAS to ensure accurate detection. If you have a private well:

1. Contact state or county environmental offices to see if they offer free or subsidized PFAS testing.

2. Choose an EPA-approved method (such as EPA Method 537.1) for collecting and testing water samples.

3. Compare any detected PFAS levels against the proposed federal MCL of 4 ppt for PFOA and PFOS or existing state advisory levels, if any.

For soil testing, commercial labs can measure PFAS concentrations in samples collected from yards, farmland, or near old fire-training sites. If you suspect contamination, I recommend seeking guidance from the DEQ to confirm sampling protocols and interpret results.

Do you qualify for a PFAS lawsuit in Wyoming?

Residents who have experienced health problems or property damage due to PFAS may wonder if they qualify for legal remedies. Lawsuits typically target manufacturing companies or organizations that knowingly mishandled or did not adequately disclose PFAS risks. In 2024, the CDC’s alert on kidney cancer risk and the Jackson Hole Airport Board’s lawsuit have highlighted growing legal activity throughout the state.

Personal injury or property damage claims can hinge on proving:

• Documented exposure to PFAS above state or federal guidelines.

• A connection between contamination and a diagnosed illness or loss (such as decreased property value).

• Evidence that a company, agency, or other party contributed to the contamination through negligence or misconduct.

If you suspect PFAS-related illness or property damage, you may want to consult an attorney specializing in environmental litigation. Additional legal guidance is available at the PFAS Lawsuit page of Legal Claim Assistant.

Moreover, some individuals have pursued lawsuits against large chemical companies (for example, DuPont) alleging PFAS negligence or harm.
