The HMUA takes potential impacts to public health very seriously and works to ensure that its water is in compliance with all Federal and State standards. In NJ, the maximum allowable contaminant level for Arsenic is 0.005 milligrams per liter (mg/l) or 5 parts per billion (ppb).  The USEPA’s legal limit for Arsenic is 10 ppb.  The Federal and NJ State Primary and Secondary Drinking Water Standards are provided on the NJDEP website at:

Arsenic data from various points in HMUA’s water system, reported by the laboratory to NJDEP as required, is available on the NJDEP website at:

The HMUA’s laboratory testing results for Arsenic are consistently well within the USEPA and NJDEP standards, with the majority of the sample results being less than (<) what can be detected by the laboratory testing method.
