Waterworks District 7
EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Louisiana Department of Health and Hospitals, as well as information from the U.S. EPA Enforcement and Compliance History database (ECHO). For the latest quarter assessed by the EPA (July 2018 - September 2018), tap water provided by this water utility was in compliance with federal health-based drinking water standards.
Nitrate and nitritecancer✕
Nitrate and nitrite enter water from fertilizer runoff, septic tanks and urban runoff. These contaminants can cause oxygen deprivation for infants and increase the risk of cancer. Nitrite is significantly more toxic than nitrate. Click here to read more about nitrate.
How your levels compareThe State and National averages were calculated using the averages of the contaminant measurements for each utility in 2015.
ppm = parts per million.
Health risks of nitrate and nitrite in excess of health guideline
The health guideline of 0.14 ppm for nitrate and nitrite was defined by based on the equivalent health guideline for nitrate, as defined in a peer-reviewed scientific study by EWG. . This health guideline protects against one-in-one-million annual cancer risk level.

This utility detected Tritium.
Radiological contaminants leach into water from certain minerals and from mining. Drinking water contamination with radioactive substances increases the risk of cancer and may harm fetal development.
Includes chemicals detected in 2015 for which annual utility averages exceeded an EWG-selected health guideline established by a federal or state public health authority; radiological contaminants detected between 2010 and 2015.
