NORTH CALDWELL, NJ · 6,000 people served · EPA PWSID NJ0715001

The bottom line

NORTH CALDWELL WATER DEP (NORTH CALDWELL, NJ), which serves about 6,000 people, has no health-based drinking-water violations on record since 2016. Its most recent lead 90th-percentile sample was 2.87 ppb, within the 15 ppb federal action level. EPA's UCMR5 program detected PFAS 'forever chemicals' in this system: PFOA (0.0089 µg/L), PFPeA (0.0079 µg/L), PFHxA (0.0067 µg/L). PFOA/PFOS levels exceed the 2024 federal limit of 4 ppt (0.004 µg/L). A certified water filter can reduce these at the tap — see the certified options for each below.

Sources & method. Contaminant levels and violations come from EPA's Safe Drinking Water Information System (health-based violations, 2016–present); PFAS from EPA UCMR5 monitoring (2023–2025). Levels shown are the highest recorded value in the violation records; a violation means the contaminant exceeded its federal limit at the system level. Your home's water can differ from the system average. Public domain data; we are not affiliated with the EPA.
