Which statement about TCEQ surface water treatment requirements is correct?

• A. The TCEQ requires pretreatment, pre-disinfection, taste and odor control, coagulation, sedimentation, filtration, covered storage, and terminal disinfection.
• B. The TCEQ requires pretreatment and filtration only.
• C. The TCEQ requires taste and odor control and disinfection only.
• D. The TCEQ requires coagulation and sedimentation only.

Answer: (A)

The main idea here is that surface water treatment under TCEQ requires a complete treatment train that protects water quality from source to distribution. Pretreatment starts the process by removing large particles and protecting downstream equipment. Coagulation and sedimentation then form and settle out smaller particles, reducing turbidity and helping subsequent steps work more effectively. Filtration catches remaining suspended material to produce clearer water. Taste and odor control addresses organic compounds that can affect palatability and may influence disinfection performance. Covered storage protects the treated water from recontamination before it’s distributed. Finally, terminal disinfection provides a residual disinfectant as water enters the distribution system, ensuring ongoing microbial protection. Together, these components cover the full sequence and safeguards expected in a compliant surface water treatment system, which is why this option is the best match.
