When the pH of the sewage is too high, this is usually an indicator of a ___ material released into the collection system.

High pH means the wastewater is very basic. Caustic substances are strong bases that raise the pH of the sewage, so a spike in pH is a good sign that caustic material—like strong industrial cleaners or process chemicals containing bases—has been released into the system.

If the discharge were acidic, the pH would drop; neutral materials would keep pH around 7; oxidizing agents can vary and aren’t defined by a high pH, so they aren’t the typical indicator for a high pH situation.
