How could you confirm that an acid waste discharge has occurred in the sanitary sewer?

• A. pH of the wastewater would rise
• B. pH of the wastewater would drop
• C. Increase in volatile suspended solids
• D. Dissolved oxygen would exceed saturation

Answer: (B)

The confirmation of an acid waste discharge in the sanitary sewer system would result in a drop in the pH of the wastewater. Acids decrease the pH level, meaning that the wastewater becomes more acidic. This change can be measured with pH testing equipment. An acid discharge can come from various sources, such as industrial processes, and when introduced into the sewer, it can disrupt the natural balance of the wastewater. An appropriate pH for wastewater is typically around neutral (pH 7). A decrease in pH to below this value indicates the introduction of acidic substances. The other choices suggest changes that would not be indicative of an acid waste discharge. A rise in pH, for instance, suggests a more alkaline discharge, which does not confirm acid presence. Similarly, increases in volatile suspended solids or dissolved oxygen exceeding saturation do not directly correlate with an acid discharge and could result from other environmental or operational factors.
