Which parameters must be reported monthly to the TCEQ?

The correct answer identifies parameters that are crucial for assessing the quality of surface water and ensuring compliance with TCEQ regulations. pH, alkalinity, and turbidity are essential indicators of water quality that must be monitored regularly.

pH indicates how acidic or basic the water is, which can affect both aquatic life and chemical processes in the water. Alkalinity helps to buffer the water's pH, preventing drastic changes that could be harmful to the ecosystem. Turbidity measures the clarity of the water, which can be influenced by suspended solids; high turbidity can harm aquatic organisms and impede photosynthesis in aquatic plants.

Monthly reporting of these parameters allows TCEQ to ensure that water quality is maintained and any deviations from acceptable standards are promptly addressed to protect public health and the environment. Monitoring these specific parameters is essential in managing and overseeing surface water quality effectively, which aligns with regulatory requirements set by TCEQ.

The other parameters mentioned, while important in other contexts, do not have the same requirement for monthly reporting as specified under TCEQ guidelines for surface water licensees.
