Don't litter. Even pet waste should be picked up off your lawn and properly disposed. Otherwise, rain can wash the bacteria directly into our rivers, lakes and streams.

Change One Thing

This summer, buy locally grown fruits and vegetables. When you shop local, you help offset greenhouse gas emissions and other pollutants associated with the transportation of food. Plus, you're supporting the farmers in your own community! Buying local just makes good sense.
