PFAS in Minnesota Water What You Need to Know to Protect Your Health

What Are PFAS and Why Minnesotans Should Care

PFAS, or per- and polyfluoroalkyl substances, are a group of human-made chemicals that have been widely used since the 1940s. You’ll find them in nonstick cookware, stain-resistant fabrics, firefighting foam, and even food packaging. Their durability—which made them so useful—also makes them a problem. PFAS don’t break down easily, and they can build up in water, soil, and even our bodies over time.

In Minnesota, PFAS contamination has emerged as a serious concern. Studies from the Minnesota Pollution Control Agency (MPCA) have detected PFAS in lakes, rivers, and groundwater across the state. This issue affects thousands of homes, especially those relying on private wells or municipal water near industrial areas.

How PFAS Get Into Minnesota's Water Supply

PFAS enter the water supply through multiple channels. In Minnesota, the most common sources include:

• Industrial discharge: Factories using PFAS in production release waste into nearby water systems.
• Firefighting foam: Used for decades at military sites, airports, and fire training centers.
• Landfill runoff: PFAS leach into the groundwater from disposed consumer goods.

Communities near places like Cottage Grove and Lake Elmo have already faced PFAS contamination. In some cases, long-term exposure happened before testing became common. The state has begun tracking PFAS contamination more aggressively, but there's still a long way to go.

Health Risks of PFAS Exposure

PFAS are often referred to as “forever chemicals” because they accumulate in the body over time. Even small amounts can pose serious health risks:

• Hormonal disruption: PFAS can interfere with thyroid function and reproductive health.
• Immune system suppression: Studies show PFAS reduce vaccine efficacy in children.
• Increased cancer risk: Some PFAS have been linked to kidney and testicular cancers.
• Developmental effects: Infants and pregnant women are especially vulnerable to growth and learning impairments caused by exposure.

According to the Centers for Disease Control and Prevention (CDC), nearly all Americans have PFAS in their blood. That’s why reducing exposure through clean water is crucial—especially for Minnesota residents who rely on groundwater.

Testing Water for PFAS in Minnesota

You can’t see, taste, or smell PFAS. The only way to know if they’re in your water is to test for them.

If your home or business is located near industrial sites, military bases, or areas flagged by the MPCA, it’s strongly recommended to get your water tested. Finken offers professional water testing across Minnesota—including St. Cloud, Baxter, Brooklyn Park, and Melrose.

Our testing process is quick and comprehensive:

• We collect water samples on-site.
• Samples are sent to certified labs for PFAS detection.
• Results help guide the next steps for filtration or system upgrades.

Effective Solutions to Remove PFAS from Drinking Water

Not all filters are equal when it comes to removing PFAS. Finken recommends the following proven technologies:

• Reverse Osmosis Systems: These systems use semi-permeable membranes to remove up to 99% of PFAS. Ideal for drinking water.
• Granular Activated Carbon (GAC): This method traps PFAS particles in carbon media. Best for whole-home treatment.
• Ion Exchange Resins: Targets specific PFAS compounds with high efficiency.

Each of these solutions can be installed and maintained by Finken’s expert technicians. We help you determine the right system based on your household size, usage, and contamination levels.
