Before discharging chemically treated water, what parameters should be tested?

• A. Temperature and dissolved oxygen
• B. pH and turbidity limits
• C. Nutrients and heavy metals
• D. Chlorides and sulfates

Answer: (B)

Testing the pH and turbidity limits of chemically treated water before discharge is essential for several reasons. Firstly, maintaining the appropriate pH levels is crucial because it affects the solubility and biological availability of various pollutants. Discharge with a pH outside the acceptable range can harm aquatic life and violate regulatory standards. Also, pH levels can influence the efficiency of any chemical treatments applied, making this an essential parameter to monitor. Secondly, turbidity is an important measure of water clarity, which can indicate the presence of suspended solids, pollutants, or algae. High turbidity can harm aquatic ecosystems by blocking sunlight and disrupting the food chain. Testing turbidity ensures that the water being discharged does not adversely affect the receiving water bodies. By monitoring these parameters, water quality can be better managed, ensuring compliance with environmental regulations and protecting ecosystems from harmful discharges.
