Bonita Water System

 

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.

This water utility has its own treatment plant or water supply, and also buys or otherwise receives some of its finished water from one or more public water utility systems to provide water for a part of its service area and customers. The list below includes the names of the supplemental water suppliers, with links to their water quality testing data.
