This 4.5-minute video can be used to educate elected officials and new program staff about illicit discharge detection and elimination
Illicit Discharge Detection and Tracking Guide
This mini-guide contains procedures for detecting and tracking illicit discharges through a desktop assessment of illicit discharge potential, field screening of outfalls to detect illicit discharges and drainage area investigations to locate and remove the source of the discharge.
Pollutant Load Calculator
This spreadsheet uses raw data from outfall screening and from instream baseflow sampling to make an initial determination of flow sources (e.g., wastewater, tap water), calculate nutrient loads for each outfall and compare pollutant loads from outfalls to baseflow within the stream itself.
Illicit Discharge Detection & Elimination Manual
2004 illicit discharge detection and elimination guidance manual produced by the Center for Watershed Protection. Primarily for use by local governments but this resource may be helpful for others as well.
