PFAS Contamination May Have Lasting Effects on Your Health

While studies on the effects of PFAS are ongoing, one thing is clear — these contaminants have a lasting effect on your health. PFAS have been making the news for a couple of years now, as EPA testing has found several contaminated sites in Montana. The complete health risks of PFAS have not yet been ascertained, but they have been linked to cancer. 

If you have become ill or received a cancer diagnosis while living within one of the contaminated zones, you may be entitled to compensation. Contact our firm today for more information, or keep reading to learn more about PFAS contamination in Montana.

What are PFAS?

Per- and polyfluoroalkyl substances (PFAS) are also called “forever chemicals” because they do not break down in the environment. These substances are found in many products used by both companies and consumers, as well as the military and other organizations. 

Some of the uses for PFAS include:

PFAS are not hazardous in small amounts, but large concentrations have been known to cause cancer and other serious illnesses. The most common way this contamination occurs is through improper disposal of items and substances containing PFAS. PFAS are prevalent in Montana due to a lack of regulation and enforcement. 

How Widespread is PFAS Contamination in Montana?

The Montana Department of Environmental Quality (DEQ) website indicates that there are five sites of concern, and the contamination has proven to be worse than initially believed.

According to the DEQ, the five Montana sites with dangerous levels of PFAS contamination are:

The drinking water at these sites has been deemed safe, but the groundwater and surface water have both been affected. According to the experts interviewed by Yellowstone Radio, the real danger is in eating fish that have been living in this water. 

What is Montana Doing About PFAS Contamination?

Although late to the scene, the state of Montana is trying to keep its citizens safe. However, many people have already become ill as a result of PFAS contamination. 

The Montana DEQ website lists these illnesses linked to PFAS contamination in Montana:

Montana DEQ and the US EPA are working together to reduce PFAS contamination levels in Montana. The DEQ is still testing many sites across the state and is testing drinking water in contaminated areas regularly.
