Common Pollutants

Step One: What Are the Permit Limits?

Municipalities typically have limits for Flow, BOD, pH, DO and Total Suspended Solids. They may also have limits for other pollutants such as Phosphorous and Chlorine.

To find these limits, look under the "parameter" column for Flow, BOD, Total Suspended Solids, DO and pH to find out how much the city can discharge.
