Illicit discharges occur when chemicals, fertilizers, and wastes contaminate our drainage system. These can be things like soap, salt, dirt, and engine fluids from washing your car; food grease and oil from a leaky dumpster; paint and other household chemicals; and even leaves and grass clippings. You are the best at helping us keep our waterways clean. Please report any questionable discharges you see; all reports will be investigated. Want to know more?
