EWG's Tap Water Database

Donate

City of Port Lavaca

 

EWG's drinking water quality report shows results of tests conducted by the water utility and provided to the Environmental Working Group by the Texas Commission on Environmental Quality , 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 serious violation federal health-based drinking water standards.

This water utility buys or otherwise receives some or all of its finished water from one or more public water utility systems. EWG research suggests that this utility purchases water from a single supplier, Gbra Port Lavaca. Tap water results displayed on the utility page show the water quality testing conducted by the original water supplier and this utility.
