Analysis

HAA5 in New Jersey: what the data shows

New Jersey has 307 cities with HAA5 monitoring data from the EPA's UCMR 4 program (2018–2020). Haloacetic acids (HAA5) form when chlorine-based disinfectants react with natural organic matter in water. The state average is 12.0 µg/L — better than the 15.5 µg/L national average. 2 cities exceed the EPA MCL of 60 µg/L. HAA5 is a group of five chlorinated and brominated acetic acids. Long-term exposure above the MCL is associated with increased cancer risk and adverse reproductive outcomes. The EPA classifies total HAA5 as a probable human carcinogen at elevated concentrations. Activated carbon filtration (especially granular or block carbon) is effective at reducing HAA5. Running water through a refrigerator filter or letting it sit in an open pitcher for 30 minutes also helps, as some HAA5 species are volatile. Boiling does not remove disinfection byproducts and may concentrate them.

FAQ

Frequently asked questions about haa5 in New Jersey

What is HAA5 and why does it appear in New Jersey tap water?

HAA5 (haloacetic acids) are disinfection byproducts that form when chlorine reacts with naturally occurring organic matter in source water. They are a normal byproduct of the disinfection process that makes water safe to drink. 2 cities in New Jersey exceed the EPA MCL of 60 µg/L. The state average is 12.0 µg/L.

How can I reduce HAA5 exposure from New Jersey drinking water?

Activated carbon filters (granular or block) effectively reduce HAA5. Refrigerator filters and under-sink carbon systems are convenient options. Unlike lead or PFAS, HAA5 levels can also be reduced by letting water stand in an open container, as some species evaporate. Boiling does NOT remove HAA5 and can concentrate them by reducing water volume.

Which New Jersey cities have the highest HAA5 levels?

The cities with the highest average HAA5 concentrations in New Jersey are: Belleville Town-0701 (65.5 µg/L), Newark-0714 (62.5 µg/L), Bloomfield Town-0702 (56.4 µg/L), Nutley Town-0716 (49.0 µg/L), East Orange City-0705 (47.4 µg/L). Note: this data is from UCMR 4 testing (2018–2020) and may not reflect current levels.
