More Than a Testing Lab

Compliance testing is only useful if you know what to do with the results. Eastex operates in both an advisory and analytical capacity, which means we don't just deliver data. We help you interpret it, report it, and act on it before a violation shows up on your record.

With 100+ years of combined staff experience navigating TCEQ requirements, we've guided clients through every major regulatory change in the Texas water industry. From the Revised Total Coliform Rule to Lead and Copper Rule Revisions to the new PFAS MCLs, our approach has always been the same: get ahead of it, prepare our clients, and make the transition as smooth as possible.

What We Do

Compliance support across the full regulatory lifecycle.

01

DMR Support

We complete and file discharge monitoring reports on your behalf, including electronic submission through NetDMR. Your results go directly from our LIMS to the state, verified for accuracy before they're sent.

02

TCEQ Electronic Reporting

All required analytical data reported electronically to TCEQ. Total coliform, drinking water chemistry, and compliance data submitted and confirmed, so you know the state has it.

03

Permit Limit Monitoring

Our LIMS can flag results that approach or exceed your permit limits before you even see the report. If something looks elevated, we call you. You hear it from us first, not from TCEQ.

04

Compliance Counseling

Questions about sampling frequency, which parameters your permit requires, or how a new regulation affects your operations? Call us. This is what we do.

05

Pretreatment Programs

Manhole sampling, source identification, grease trap compliance, and pretreatment plan development. We handle the sampling, analysis, and reporting so your pretreatment program stays on track.

06

Regulatory Guidance

When new regulations are coming, we don't wait for you to ask. We reach out, explain what's changing, and help you prepare. We've been doing this through every major TCEQ rule change for nearly 40 years.

A Track Record of Getting Ahead

Regulatory changes don't surprise our clients, because they don't surprise us. Here's a sample of the transitions we've guided clients through:

2024
EPA PFAS MCLs

First-ever enforceable limits on PFAS in drinking water. Monitoring required by 2027, compliance by 2029.

2017
Water Quality Parameters Expansion

New TCEQ requirements for alkalinity, calcium, chloride, conductivity, hardness, iron, manganese, pH, sodium, sulfate, temperature, and TDS.

2016
Electronic DMR Reporting

Transition from paper to electronic DMR filing through NetDMR. We handled the switch for our clients and continue to file on their behalf.

2016
Revised Total Coliform Rule

Multi-year preparation effort with clients. Sampling plan updates, new monitoring requirements, and compliance documentation.

2015
Lead and Copper Rule

Extensive guidance on sampling, water quality parameters, corrosion control, and TCEQ form updates. Provided bottles, forms, and electronic reporting.

Who We Work With

Compliance requirements vary by permit type, system size, and regulatory program. We serve clients across the full spectrum of Texas water and wastewater compliance.
