Water Quality

Contaminants in tap and bottled water including PFAS, lead, and chlorination byproducts.

Why it matters

Water is a daily exposure vector. PFAS ('forever chemicals') are now detected in most U.S. water supplies.

What is known

EWG Tap Water Database provides zip-code level data. Reverse osmosis and activated carbon filters address most common contaminants. Bottled water is not necessarily cleaner.
