What's in North Salt Lake's water
Total Trihalomethanes (TTHM)

Haloacetic Acids (HAA5)
Violation on record
1 EPA violation on record (most recent 2021). HAA5 are a second group of chlorine disinfection byproducts formed when chlorine reacts with organic matter in water. Long-term exposure is associated with increased cancer risk and possible developmental effects. They commonly occur together with trihalomethanes.
