Wastewater Testing
Permit-Driven Testing
Every wastewater discharge permit has specific monitoring requirements, and every missed parameter or late report carries real consequences. Eastex provides the full suite of wastewater analysis required for TPDES compliance, backed by the regulatory expertise to help you interpret results and file on time.
We know the parameters on your permit because we've been running them for facilities like yours for nearly 40 years. When your results look unusual, we don't just report the number. We flag it, we call you, and we help you figure out what's happening before your next DMR is due.

Compliance Support
Testing is half the job. The other half is making sure your results get reported correctly and on time. Eastex provides end-to-end compliance support for wastewater operations:
- DMR filing — We complete and submit discharge monitoring reports through NetDMR, verified for accuracy before they go to the state.
- TCEQ electronic reporting — All required data submitted electronically and confirmed received.
- Permit limit alerts — Our LIMS flags results approaching your permit limits. You hear it from us first.
- Pretreatment programs — Manhole sampling, source identification, and grease trap compliance. Sampling, analysis, and reporting handled as a complete service.
- Regulatory guidance — When permit requirements change, we help you understand what's different and what you need to do.
