PFAS in Idaho

PFAS in Idaho’s drinking water

PFAS can reach drinking water through soil infiltration, industrial discharge, and the use of firefighting foams. Once in service lines or public wells, PFAS can remain undetected unless specific testing is performed. The EPA has set a Maximum Contaminant Level (MCL) of 4 parts per trillion (ppt) for PFOA and PFOS in drinking water, though Idaho does not currently include these substances under its primary drinking water regulations.

Known contamination zones

Based on available data, two military facilities in southern Idaho stand out as known contamination zones:

• Mountain Home Air Force Base, where Department of Defense testing confirmed PFAS detections in nearby water sources.
• Gowen Field Boise/Airport Training Area, which reported measurable levels of PFAS during monitoring efforts.

Local residents in these areas frequently rely on private wells, which may not be regularly tested for PFAS. The Idaho DEQ advises routine sampling and collaboration with public health departments if residents suspect possible contamination, especially near known hot spots.

Common PFAS sources: Firefighting foam, military bases, industrial sites

Aqueous film-forming foam (AFFF), widely used in aircraft crash response and large-scale fuel fires, is often implicated in PFAS contamination near military bases. In Idaho, both active and former military installations have used AFFF for training and emergency response. Industrial facilities that manufacture or process PFAS-containing products can also discharge or dispose of these chemicals, allowing them to migrate into groundwater. Although some industrial operations have phased out PFOA and PFOS, many related compounds remain in use.

Idaho DEQ and EPA testing data

The Idaho DEQ participated in the EPA’s Unregulated Contaminant Monitoring Rule (UCMR3) testing between 2013 and 2015. Under this rule, 33 public water systems in Idaho were sampled for PFAS. According to Idaho’s DEQ reports, no PFAS were detected above the method detection limit during that period. However, the absence of high readings in these particular systems does not rule out localized contamination.

Ongoing efforts by the DEQ, alongside EPA interim health advisory levels for PFOA (0.004 ppt) and PFOS (0.02 ppt), guide further study and voluntary sampling. Local authorities suggest that if your water is near a potential industrial or military source, you should consider having it tested.

PFAS in Idaho’s soil and environment

Beyond water, PFAS in Idaho can also accumulate in soil. This can happen when residues from manufacturing, firefighting foam, or consumer products make their way into landfills, then leach into soil over time. Because these substances do not break down easily, contamination often persists, creating a long-term ecological risk.

Contaminated soil from sludge or landfill leachate

Wastewater treatment plants and landfills sometimes distribute treated sludge, also known as biosolids, on agricultural fields. If the sludge contains PFAS, it can lead to contaminated soil. The PFAS can then migrate, entering crops and livestock. According to studies conducted by the EPA, certain PFAS can remain in soil for decades, meaning that one contamination event can have lasting implications.

Potential impact on crops, livestock, and ecosystems

When PFAS accumulate in soil, they may move into plants like alfalfa or corn, which can then be fed to livestock. Over time, this bioaccumulation can affect the broader food chain, potentially leading to low-level exposure for many consumers. Researchers also note that wildlife in affected areas may show elevated PFAS levels, prompting concerns regarding biodiversity, reproduction, and ecosystem resilience.

Health effects of PFAS exposure

Individuals who ingest, inhale, or come into contact with PFAS may experience various health effects, though the degree depends on exposure levels, duration, and personal factors like age or pre-existing health conditions. According to the CDC, PFAS exposure at elevated concentrations may contribute to:

• High cholesterol
• Changes in liver enzymes
• Low infant birth weights
• Elevated risk of kidney and testicular cancer
• Weakened immune response

The link between PFAS and weakened antibodies is particularly concerning for older adults and immunocompromised individuals.

Diseases linked to PFAS in Idaho

Epidemiological studies have explored the connection between PFAS and human disease. Although PFAS contamination in Idaho is relatively less publicized compared to some other states, the state has seen concerning patterns in specific diseases. Researchers recommend continued monitoring as more is learned.

Kidney cancer

On January 26, 2024, the Centers for Disease Control and Prevention (CDC) issued an update highlighting the increased risk of kidney cancer associated with PFAS in Idaho. PFOA, in particular, has been closely associated with renal disease. People living near identified PFAS hotspots or those who have worked in PFAS-related industries may face higher risks, especially if their water supply was contaminated.

Testicular cancer

National research has shown associations between PFAS exposure and testicular cancer, likely due to hormonal disruptions. Although there are fewer data specific to Idaho, experts caution that individuals with occupational exposures should take precautionary measures, including regular health screenings.

Thyroid and liver damage

PFAS can affect endocrine pathways, raising concerns about thyroid issues, especially in women. Idaho has experienced an uptick in thyroid cancer diagnoses near industrial sites, though comprehensive studies on direct PFAS links are ongoing. Additionally, some PFAS can disrupt liver function. When combined with other environmental stressors, even moderate PFAS exposure might contribute to liver damage over time.

Immune system problems

Research by the National Toxicology Program found that PFOA and PFOS have the potential to suppress the immune system. This means the body’s ability to fight off pathogens could be compromised. Residents with chronic illnesses or compromised immunity may be more susceptible to additional health complications if PFAS levels in their environment are elevated.

Reproductive and developmental issues

Some PFAS compounds may interfere with hormone regulation and fetal development. Pregnant women exposed to high PFAS levels risk transferring these chemicals to the fetus through the placenta. Infants can be exposed via breast milk or formula prepared with contaminated water. Using bottled water or alternative sources might help reduce risk for infants in areas where PFAS are detected in water supplies.

How is Idaho responding to PFAS contamination?

Idaho’s response to PFAS contamination includes voluntary sampling programs, coordination with federal agencies, and information campaigns to raise awareness of potential health risks. However, no enforceable PFAS regulations currently exist at the state level.

State and local water testing efforts

The Idaho DEQ received federal grant funds in 2020 to conduct additional sampling of public drinking water systems. This program uses EPA Method 533, which detects short-chain PFAS compounds. Testing began in 2021 and continues as funding allows. Officials encourage private well owners to consider certified lab testing, especially if they live near documented contamination zones.

Federal oversight and funding support

On the federal level, the U.S. EPA has proposed establishing PFAS as regulated contaminants in drinking water nationwide. Although this process is ongoing, interim advisories for PFOA (0.004 ppt) and PFOS (0.02 ppt) are already in place. Idaho follows EPA guidance in its public education campaigns, urging residents to stay informed of potential PFAS exposures. These efforts also tie into a larger government-wide initiative led by the White House to advance clean drinking water and reduce pollutants related to PFAS.

Community education and action

Community awareness plays a key role in Idaho’s approach to PFAS. Public meetings, local news coverage, and health department briefings present verified data and explain testing procedures. Some neighborhoods have formed citizens’ groups that advocate for stricter regulations or more frequent monitoring. Residents are also sharing resources on alternative filtration methods and seeking legal counsel if they believe a polluter is liable for contamination.

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

Yes. If I lived near a known PFAS Idaho hot spot, I would start by contacting the Idaho DEQ or my local health district for recommendations on certified laboratories. The EPA website also maintains a list of accredited labs that can detect low levels of PFAS in water, soil, and even household dust. Testing fees vary, but it is often less expensive if coordinated through local programs.

When testing soil, consider whether biosolids or industrial runoff might have been applied to your property. Laboratory analysis can reveal whether PFAS levels exceed EPA-recommended thresholds. Once you have the results, you can consult with state or federal agencies to understand mitigation options such as soil remediation or specialized drinking water filters.

Do you qualify for a PFAS lawsuit in Idaho?

If you believe PFAS exposure has harmed your health, property, or both, it may be possible to build a legal claim. Compensation may include medical costs, lost wages, property devaluation, and other damages. Typically, you would need:

• Evidence that water, soil, or air on your property contains PFAS
• A demonstrated link between the contamination and your health issues or property damage
• Documented exposure pathways (e.g., relying on a well that tested above EPA health advisories)

Lawsuits often target chemical manufacturers, industrial plants, or other entities responsible for releasing PFAS. Idaho does not have a statewide PFAS drinking water regulation yet, but if you feel your concerns were ignored or your community was not properly notified, a legal action may still apply.
