Public Water Systems
Your Compliance, Our Priority
Public water systems operate under the most scrutinized regulatory framework in the water industry. SDWA, TCEQ drinking water rules, LCRR, PFAS MCLs, UCMR 5, and chemical monitoring schedules all run on different timelines with different requirements. Missing a monitoring window or submitting data from an unaccredited lab creates problems that are entirely preventable.
Eastex holds TCEQ Drinking Water approval and has been continuously NELAP/TNI accredited since 2007. We don't just run your tests. We provide the bottles, guide collection procedures, submit results electronically to TCEQ, and verify that the state received them. When a new compliance requirement comes down, we reach out to explain what's changing and help you update your monitoring plan.
