Illicit Discharge Detection & Elimination (IDDE)� Program focuses on finding the
sources of illicit discharges to local water ways� Identify an outfall with high E. coli� Outfalls are placed on a list for
investigation� Verify high E. coli and flow
measurement� If E. coli is high, begin source tracking� Some discharges may be intermittent
and require additional sampling
