in Drinking Water
PFAS (per- and polyfluoroalkyl substances) are a group of thousands of synthetic chemicals that don't break down in the environment or the human body. They're called "forever chemicals" because they persist indefinitely.
4 ppt for PFOA/PFOS (proposed 2024)
This is the maximum contaminant level (MCL) that water systems must meet by law.
4 ppt (EPA health advisory)
The level below which no adverse health effects are expected.
Exposure to pfas (forever chemicals) in drinking water can cause various health problems:
PFAS (Forever Chemicals) can enter drinking water from various sources:
| Rank | City | PFAS (Forever Chemicals) Level | Overall Grade |
|---|---|---|---|
| #1 | Rochester | Detected | F |
| #2 | ST CLOUD | Detected | F |
| #3 | Park Rapids | Detected | F |
| #4 | Ramsey | Detected | F |
| #5 | Owatonna | Detected | F |
| #6 | Hutchinson | Detected | F |
| #7 | Foley | Detected | F |
These filtration methods are effective at removing pfas (forever chemicals) from drinking water:
PFAS (per- and polyfluoroalkyl substances) are a group of thousands of synthetic chemicals that don't break down in the environment or the human body. They're called "forever chemicals" because they persist indefinitely.
Exposure to pfas (forever chemicals) in drinking water can cause: Increased cholesterol levels, Changes in liver enzymes, Decreased vaccine response in children. This is considered a high-risk contaminant.
The EPA limit for pfas (forever chemicals) is 4 ppt for PFOA/PFOS (proposed 2024). The health guideline is 4 ppt (EPA health advisory).
The most effective methods to remove pfas (forever chemicals) include: Granular activated carbon (GAC) filters - effective for some PFAS; Reverse osmosis (RO) systems - removes most PFAS.
