Drinking water operator research tool
Choose a state, track, and stage to build questions for the operator-certification program. The tool never invents a class, fee, timeline, or approved course.
Call sheet for Texas
- Use EPA's operator-certification contact directory to open the current state program website.
- Which treatment-operator class matches the target public water system, source, and processes?
- May I test before completing experience, is an operator-in-training route available, and who must verify qualifying hours?
- How is the target public water system classified, and which credential is required for the planned role?
- Which exam bulletin, references, calculator policy, fees, and testing provider are current?
- Will the exact proposed course, topic, provider, and delivery format count for this credential and cycle?
This tool organizes questions. It does not determine eligibility, class, experience credit, course approval, or public-water-system compliance.
Use the source-linked operator guide to understand the credential, operator track, and public-water-system layers.
