Water Adjustment Notice

Important Notice

January 2020

The Assumption Parish Waterworks District 1 is currently in violation of the maximum contaminate level (MCL) for haloacetic acids as set forth by the State [Part XII of the Louisiana State Sanitary Code (LAC 51 XII)] and the Federal Primary Drinking Water Regulations (40 CFR Part 141).

The United States Environmental Protection Agency (EPA) and the Louisiana Department of Health (LDH) set drinking water standards and requires the disinfection of drinking water.  Where disinfection is used in the treatment of drinking water, disinfectants combine with naturally occurring organic and inorganic matter present in water to form chemicals called disinfection byproducts (DBPs).  EPA and LDH set standards for controlling the levels of disinfectants and DBPs in drinking water, including trihalomethanes (THMs) and haloacetic acid (HAAs).  Some people who drink water containing HAA5s in excess of the MCL over many years may have an increased risk of getting cancer.

In December 1998, EPA set enforceable drinking water standards for TTHMs at 80 parts per billion (ppb) and for HAA5 at 60 parts per billion (ppb) to reduce the risk of cancer or other adverse health effects.  Compliance with the HAA5 standard is determined by calculating a locational running annual average (LRAA) of quarterly HAA5 sample results.  Compliance calculations performed for the fourth quarter of 2019 show that the system’s current HAA5 LRAAs are 63 ppb at one site and 61 ppb at another: thus, the system is currently in violation of the HAA5 standard.

Please share this information with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses).  You can do this by posting this notice in a public place or distributing copies by hand or mail.

This is not an emergency.  If it had been, you would have been notified immediately.  EPA and LDH do not consider this violation to have any serious adverse health effects on human health as a result of short-term exposure; however, continued long-term exposure to TTHMs and HAA5 levels above the standard (e.g., 20 years of exposure) has the potential to have serious adverse effects on human health.

We have made treatment changes which showed better results on in-house testing and our results for December verified this. The LRAA for two sites are still over the limit due to the results from two previous quarters and causing this notice.  APWW strives daily to produce the highest quality water possible to our customers and we are always trying new ways to do so.   If you have any questions please call Ginger Rushing, Plant Superintendent, at 985-369-6156.
