Over the last few years, growing awareness around water quality has led to more conversations about a group of synthetic chemicals known as PFAS, including PFOA and PFOS. Often referred to as “forever chemicals,” these compounds are known for their ability to linger in the environment and the human body for years without breaking down. Understanding what PFAS are and how they affect your drinking water is a critical step in protecting your family’s health.

At Tri-County Water, we take clean water seriously. We’re here to help you understand what these chemicals are, why they matter, and how to reduce or eliminate them from your home water supply.

With over 58 years of experience serving homes across Mid-Michigan and West Michigan, we know the unique challenges that local water sources can present. In this article, we’ll break down the benefits and limitations of two common filtration options, water pitcher filters and reverse osmosis systems, so you can make the best decision for your household’s needs.

PFAS (Per- and Polyfluoroalkyl Substances) are a large family of human-made chemicals that have been used in countless household and industrial products since the 1940s. These substances are valued for their resistance to water, grease, and heat. Unfortunately, that same durability makes them difficult to remove once they enter the environment, or your drinking water.

Two of the most studied and widespread PFAS compounds are:

• PFOA (Perfluorooctanoic Acid): Historically used in non-stick cookware, waterproof gear, and some fire-fighting foams.

• PFOS (Perfluorooctane Sulfonate): Commonly found in stain-resistant fabrics, certain pesticides, and fire-fighting materials.

Both PFOA and PFOS are highly persistent in soil and water, and they can accumulate in the human body over time, potentially leading to health concerns.

PFAS chemicals can enter the environment through a variety of pathways, including:

• Industrial waste discharge

• Landfill runoff

• Firefighting foam use near airports and military bases

• Application of biosolids (treated sewage sludge) on farmland

Once PFAS enter the ground or surface water, they can migrate into private wells and municipal water systems. Because these chemicals don’t easily degrade, they can remain in the water supply for decades unless treated.

Current research suggests PFAS exposure may be linked to a variety of health effects. These can vary based on the level and duration of exposure but may include:

• Elevated cholesterol levels

• Impacts on liver function

• Developmental delays in infants and children

• Reduced vaccine response

• Pregnancy complications such as high blood pressure

• Increased risk of kidney and testicular cancer

Although more research is ongoing, existing studies raise enough concern to warrant taking action, especially when it comes to your drinking water.

1. Activated Carbon Filtration

This technology uses specially treated carbon to absorb contaminants as water flows through. It’s a cost-effective solution and can be integrated into whole-home filtration systems. However, proper system design and maintenance are key to long-term effectiveness.

2. Reverse Osmosis (RO) Systems

RO systems force water through a semipermeable membrane, blocking PFAS and other impurities. These are ideal for point-of-use applications like under-sink systems in kitchens. Whole-house RO systems are also available for more comprehensive coverage but require a more significant investment.

3. Anion Exchange Treatment

This method uses resins that attract and bind with negatively charged PFAS molecules. It’s especially effective for reducing specific types of PFAS and can be customized based on your household’s water chemistry.

Each method has its strengths, and the best solution often depends on your specific water quality and usage. At Tri-County Water, our water treatment specialists can help you design a system that fits your needs, budget, and long-term health goals.

How to Remove PFAS from Your Water

No matter what system you choose, the first step should always be understanding what’s in your water. That’s why Tri County Water offers a free basic water test to help you assess the quality of your tap water before making any decisions.

Different regions face different water issues, and not every filter can solve every problem. Even the Environmental Protection Agency (EPA) monitors for unregulated contaminants—chemicals and pollutants not currently controlled under the Safe Drinking Water Act but that could still pose a risk to your health.

A local water assessment can help uncover not only health risks but also factors that affect the lifespan of your plumbing, water heater, and home appliances.

What’s the Government Doing?

In 2024, the EPA introduced new enforceable drinking water standards for six PFAS compounds, including PFOA and PFOS. Public water systems must begin monitoring by 2027 and reach full compliance by 2029.

But if you’re concerned about your water today, there’s no need to wait. You can start protecting your household now with a professionally designed and installed filtration system.
