Total Trihalomethanes (TTHM) MCL Violation at the Elmwood Park Water System
Our water system recent 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 September 2017 through June 2018 show that our system exceeds the standard, or maximum contaminant level (MCL) for TTHM at one location, the DPW Garage on Slater Drive. The standard for TTHM is 80 ug/L. It is determined by averaging all samples collected from each location for the last 12 months also known as the Locational Running Annual Average. The Locational Running Annual Average at the DPW Garage on Slater Drive, for September 2017 thru June 2018 was 85 ug/L.
What should I do?
- There is nothing you need to do. You do not need to boil your water or take other corrective actions. If a situation arises where the water is no longer safe to drink, you will be notified within 24 hours.
- If you have a severely compromised immune system, have an infant, are pregnant, or are elderly, you may be at increased risk and should seek advice from your health care providers about drinking this water.
What does this mean?
This is not an emergency. If it had been an emergency, you would have been notified within 24 hours.
TTHM are four volatile organic chemicals which form when disinfectants react with natural organic matter in the water.
[*People who drink water containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system, and may have increased risk of getting cancer.]
What is being done?
Additional hydrant flushing of the water system on dead-end mains including the installation of automatic hydrant flushing devices is being conducted by the DPW staff to reduce TTHM concentrations. For more information please contact Robert De Block at 973-998-9100 at De Block Environmental Services, LLC, PO Box 675 Woodland Park, NJ 07424.
