Problem Solution
Per acre, homes use more pesticides than farms. Applying fertilizer and pesticides before a rain produces large amounts of polluted runoff. Contrary to popular belief, rain does not help “soak in” the chemicals but rather washes them away down a storm drain. Once these chemicals are introduced into lakes and streams they promote the growth of algae that kills fish. By applying chemicals several days before rain is forecast, you can help your yard and the environment. Also, consider reducing the number of applications of fertilizer and pesticides.
Pet waste left on the ground gets carried away by stormwater, contributing harmful bacteria, nutrients, parasites and viruses to our river. Do not dispose of pet waste down the storm drain. Clean up after your pet and dispose of the waste down the toilet or in the garbage.
Vehicle fluids such as oil, gas, and antifreeze are the #1 surface water quality problems nationwide. Recycle used oil in a clean, sealed, plastic container. Call the Delaware Solid Waste Authority at 1-800-404-7080 or www.dswa.com for a complete list of accepted materials and drop off locations in your area.
Yard waste such as grass clippings, tree trimmings, and leaves can clog storm drains causing pooling water and creating dangerous driving conditions. Compost and use the compost for fertilizer around the yard.
Hosing off pavements washes pollutants into storm drains leading straight to the river. Sweep your debris into a proper receptacle…Not into the storm drain!
