Why Check Your Tap Water?
Lead Contamination
The EPA estimates that 10–20% of human lead exposure comes from drinking water. Lead has no safe exposure level for children and can cause irreversible neurological damage.
PFAS "Forever Chemicals"
PFAS chemicals have been detected in water supplies serving millions. The EPA issued its first federal PFAS MCLs in 2024, setting limits at 4 parts per trillion.
Disinfection Byproducts
When chlorine reacts with organic matter, it forms compounds (TTHMs and HAA5s) linked to increased cancer risk with long-term exposure.
Aging Infrastructure
Over 6 million lead service lines still deliver water to homes. The EPA's Lead and Copper Rule requires utilities to identify and replace these pipes, but it will take years.
