ATS instrumentation shall record which of the following?

ATS instrumentation shall record which of the following?

• A. Flow and pH only
• B. Flow, Turbidity, and pH
• C. Temperature, pH, and dissolved oxygen
• D. Turbidity, pH, and temperature

Answer: (B)

ATS instrumentation focuses on tracking both how much water is being discharged and the quality of that discharge. Recording flow quantifies the volume moved, which is essential for calculating pollutant loads and meeting any flow-based permit requirements. Turbidity serves as a practical surrogate for suspended solids, allowing you to gauge sediment content and assess whether erosion and sediment control practices are working. pH measures acidity or basicity, ensuring the effluent stays within permitted pH limits and indicating whether treatment adjustments are needed before discharge. Temperature and dissolved oxygen aren’t typically required parameters for ATS in standard stormwater monitoring. DO is more relevant to ecological assessments, and temperature is less directly tied to sediment control performance. A setup that omits turbidity misses a key indicator of sediment load, while one that relies on temperature instead of turbidity would fail to capture the primary pollutant signal. Hence, the required set is flow, turbidity, and pH.
