Regulatory Water Testing

The Northeast Texas Public Health District (NET Health) Laboratory is certified by the Texas Commission on Environmental Quality (TCEQ) for the bacterial analysis of public drinking water.

The quality of water is required to meet federal and state standards. There is a network of government agencies that monitor tap water suppliers and enforce drinking water standards to ensure the safety of the public.

Water suitable for drinking by humans must be free of Total Coliform organisms and E. coli, as required by the EPA for all public water systems to ensure the safety of the public.

TCEQ Microbial Reporting Form (10525 - Lab revision) is required with the submission of drinking water samples by Public Water Systems for testing to the NET Health Regional Laboratory.
