We Know How MUDs Work
MUDs operate under a specific set of pressures that most labs don't fully appreciate. Board reporting timelines, TCEQ compliance deadlines, operator responsibilities that span multiple districts, and budgets that require cost-reasonableness without cutting corners on quality.
Eastex has been the lab partner for Texas MUDs for nearly 40 years. We understand the regulatory calendar, the parameters your permit requires, and the operators who call us by name. When something in your results needs attention, you hear it from us directly, not in a compliance notice from TCEQ.
What We Provide
Testing and compliance support designed for how MUDs actually operate.

All parameters required by your TPDES permit. BOD, TSS, ammonia, fecal coliform, nutrients, metals, and everything else your DMR calls for.

We complete and file your discharge monitoring reports through NetDMR. Results go from our LIMS to the state, verified for accuracy before submission.
