PFAS in Ohio Drinking Water: What Homeowners Should Know
PFAS in Ohio Drinking Water: What Homeowners Should Know
Concerns about PFAS in Ohio drinking water have grown significantly in recent years. Homeowners across Central Ohio are asking:
-
What are PFAS?
-
Are they in my water?
-
Are they dangerous?
-
How can I remove them from my home’s drinking water?
This guide explains what PFAS are, how they enter Ohio water systems, potential health concerns, and what treatment options are available for homeowners.

What Are PFAS?
PFAS stands for per- and polyfluoroalkyl substances, a group of thousands of man-made chemicals used since the 1940s in products that resist heat, water, and grease.
They have been used in:
-
Non-stick cookware
-
Stain-resistant fabrics
-
Waterproof clothing
-
Firefighting foam
-
Food packaging
-
Industrial manufacturing
PFAS are often called “forever chemicals” because they do not break down easily in the environment or the human body.
Why PFAS Are a Concern in Ohio
PFAS contamination can occur when industrial discharge, firefighting foam use, or waste disposal sites allow these chemicals to enter groundwater or surface water.
Ohio has conducted statewide testing of public water systems, and some communities have detected measurable levels of PFAS. While many systems test below federal action levels, the concern lies in:
-
Long-term exposure
-
Bioaccumulation in the body
-
Emerging research on health impacts
The U.S. Environmental Protection Agency has recently proposed and finalized stricter limits for certain PFAS compounds, lowering acceptable levels significantly compared to previous guidelines.
Potential Health Concerns Linked to PFAS
Research is ongoing, but studies have associated long-term PFAS exposure with:
-
Increased cholesterol levels
-
Thyroid disease
-
Immune system effects
-
Developmental effects in infants and children
-
Certain cancers
-
Pregnancy complications
It is important to note that risk depends on concentration and duration of exposure.
Are PFAS in Your Ohio Water?
If you are on municipal water, your local water supplier publishes an annual Consumer Confidence Report (CCR). This report may include PFAS testing results if testing has been conducted.
However, keep in mind:
-
Not all compounds may be tested
-
Results are averages
-
Levels can vary within distribution systems
-
Well water is not automatically tested
If you rely on private well water, PFAS testing is not routinely required, and independent testing may be necessary.
How to Remove PFAS from Drinking Water
PFAS cannot be removed by boiling water. In fact, boiling may slightly concentrate contaminants.
Effective removal methods include:
1. Reverse Osmosis (RO)
Reverse osmosis systems are highly effective at reducing many PFAS compounds at the point of use, typically installed under the kitchen sink.
2. Activated Carbon Filtration
High-quality carbon filtration systems can reduce certain PFAS compounds, especially when properly sized and maintained.
3. Whole-House Filtration
In some cases, homeowners may choose whole-house treatment combined with point-of-use drinking water systems for added protection.
The best solution depends on your water source, PFAS concentration, and overall water chemistry.
Why Water Testing Is Critical
Before selecting a treatment system, proper testing is essential.
A professional water evaluation can:
-
Identify whether PFAS are present
-
Determine concentration levels
-
Evaluate other water quality factors
-
Recommend appropriately sized treatment systems
Without testing, homeowners risk either under-treating or overspending on unnecessary equipment.
Municipal Water vs. Well Water in Ohio
Municipal Water
Public systems are required to comply with federal and state regulations. If PFAS are detected above regulatory limits, utilities must take corrective action.
Private Well Water
Private wells are not regulated under the same federal standards. Responsibility for testing and treatment falls entirely on the homeowner.
If you live near industrial areas, airports, military bases, or former manufacturing sites, PFAS testing may be especially important.
Is PFAS Treatment Worth It?
Many Ohio homeowners choose additional filtration even when municipal water meets regulatory standards because:
-
Federal limits have been reduced over time
-
Research continues to evolve
-
They prefer an added layer of protection for drinking and cooking water
Whether treatment is necessary depends on your personal comfort level and actual test results.
Protecting Your Home’s Drinking Water
PFAS concerns are part of a broader conversation about emerging contaminants in Ohio’s water supply. While utilities work to meet evolving regulations, homeowners can take proactive steps to understand and improve their water quality.
The first step is always testing.
If you are concerned about PFAS in your Ohio drinking water, schedule a professional water test to determine what is actually present in your home’s supply and review the most effective treatment options available.
