Illicit Discharge Detection & Elimination

Stormwater DrainAn Illicit discharge occurs any time something other than stormwater enters a storm drain, except water from fire fighting equipment or a facility under an NPDES permit. Examples of illicit discharge can include toxic pollutants, pest control chemicals, lawn care chemicals, and pet waste.

Why is this bad?
Illicit discharges are a problem because, unlike wastewater processed at a wastewater treatment facility before moving back into the normal waterways, Stormwater does not go to a treatment facility. Instead, it will move back into the waterways filled with unwanted additives.

How to help
Follow directions on all products you use; whether you’re using chemicals to control pests, kill weeds, or fertilize your lawn, always follow the directions on the package. It will not only help you to save money by not overusing the chemical, but it will also prevent excess from entering into the Stormwater system.
