Important Information About Your Drinking Water - Haloacetic Acid (HAA5) MCL Violation - January 11, 2019


Haloacetic Acid 5 (HAA5) MCL Violation at Nutley Water Department

Our water system recently violated a drinking water standard. Although this incident was not an emergency, as our customers, you have a right to know what happened and what we did (are doing) to correct this situation.

We routinely monitor for the presence of drinking water contaminants. Testing results from December 2018 show that our system exceeds the standard, or maximum contaminant level (MCL), for HAA5. The standard for HAA5 is 60 parts per billion (ppb).  The level of HAA5 at one of our system’s locations in December 2018 was 73.2ppb.

What should I do?

At this time, no alternative sources of water is necessary.  However, if you have specific health concerns, consult your doctor.

What does this mean?

This is not an emergency. If it had been an emergency, you would have been notified immediately.

HAA5 are five haloacetic acid compounds which form when disinfectants react with natural organic matter in the water.

People who drink water containing haloacetic acids in excess of the MCL over many years may have an increased risk of getting cancer.

What Happened?  What is being done?

This is an issue with our source water supplier, Newark Water Department and their disinfection process.  When disinfectants are used in the treatment of drinking water, disinfectants react with naturally-occurring organic and inorganic matter present in water to form disinfection byproducts.  Only a small section of Nutley receives its supply from the Newark Water Department.

We have taken the following corrective action(s):

  • Hydrant flushing in the affected areas was performed to introduce fresh water into the system.
