Why do we need to worry about stormwater?

As stormwater flows over the ground it picks up pollution like oil leaking from cars, fertilizer from lawns, and bacteria from pet wastes. Stormwater is not treated to remove pollution before it enters our local waterways. Experts believe that almost 70% of the pollution in our rivers and lakes is carried there by stormwater runoff. Stormwater can also cause erosion and flooding.


Water contaminated with sediment and pollution takes more money to treat before it can be used for drinking water. Tourism and recreation businesses suffer along with residents when swimming, fishing, and boating are not allowed because of safety concerns. Damage from unmitigated flooding can raise merchant prices and insurance rates. And the list goes on. Because everyone plays a role in creating the pollution in stormwater runoff, we all have a role in cleaning it up.
