Texas Commission on Environmental Quality (TCEQ). Class C Water License Exam

Which of the following is a responsibility of a water system operator concerning water quality?

1. Monitoring electrical systems

2. Eating and drinking in the lab areas

3. Sampling and testing water regularly

4. Ignoring minor contaminant levels

The correct answer is: Sampling and testing water regularly

Sampling and testing water regularly is a critical responsibility of a water system operator because it ensures the safety and quality of the water supply. Regular monitoring allows operators to detect contaminants early, evaluate compliance with health standards, and respond promptly to any potential issues that could affect public health. This practice is essential for maintaining the integrity of the water system and safeguarding the community's health. The other options do not align with the responsibilities associated with maintaining water quality. Monitoring electrical systems, while important for operational efficiency, does not directly relate to water quality management. Eating and drinking in the lab areas poses a risk of contamination and is not permissible practice in a setting focused on water analysis. Ignoring minor contaminant levels undermines the operator's role, as even minor contaminants can indicate larger problems and may violate regulatory standards. Continuous, proactive monitoring is vital for ensuring that water remains clean and safe for consumers.
