Do you know about the forever chemicals in your drinking water?
The average concentrations in the Great Lakes don’t exceed federally recommended limits but toxicologists say there may be no safe level of exposure.

If you drink tap water out of a filtered pitcher, it is important to make sure you’re using the right type of filter depending on your local contaminants, which in some cases, might be more serious than others.
USA TODAY published a map of public drinking water systems that recently submitted test results for “forever chemicals” to the Environmental Protection Agency. Two Indiana towns were found to have chemicals over the federally dictated levels.
Here’s what we know.
What are ‘forever chemicals’?
PFAS, also known as “forever chemicals,” are defined by the EPA as long-lasting chemicals with components that break down very slowly over time.
Because of the widespread use of these chemicals, they are found in water, air, soil, fish and even human blood in varying levels. Scientific studies have shown that exposure to some of these chemicals may be linked to harmful health effects in humans and animals.
As a result, the EPA established legally enforceable levels in 2024 for six PFAS in public drinking water. Public water systems must monitor for these chemicals and take action to reduce the levels of these chemicals if they violate the EPA’s standards. They must also provide notification to the public of the violation.
Can PFAS be filtered out of water?
Not all filters reduce PFAS in water, so you should look for a filter that is specifically certified to do so, according to the EPA.
The agency recommends using the following types of water filters:
- Charcoal (Granular Activated Carbon or GAC): These filters use carbon to trap chemicals as water passes through them.
- Reverse Osmosis (RO) Systems: Reverse osmosis is a process that forces water through an extremely thin barrier that separates chemicals from the water.
- Ion Exchange Resins: Resins are tiny beads that act like powerful magnets that attract and hold the contaminated materials from passing through the water system.
PFAS detected in Indiana
While PFAS have been detected in Indiana, they have mostly been detected at lower levels. The following two public water systems in were found to have “forever chemical” levels over the EPA limit:
