DENTON, Texas The Texas Commission on Environmental Quality says that hundreds of state public water suppliers failed to test for lead and copper in their systems last year.
The Denton Record-Chronicle reports that about 1,000 out of 2,245 water suppliers failed to fulfill the testing protocol in summer 2015. Local, state and federal officials do not have current data required on lead and copper levels for about 1 in 7 of the state's 6,916 public water systems.
The state laboratory used to send sampling kits to suppliers for testing before protocol was changed to allow suppliers to choose their own laboratories, as long as it was certified. Water suppliers are now in charge of getting their own sampling kits, which led to a failure in testing.
The agency notified suppliers to test their systems in January 2014.
