Keep fuels, paints, pesticides, and other chemicals in proper containers, away from water sources. Leaks or spills can seep into the ground or be carried by rain into nearby rivers, lakes, or wells, contaminating drinking water.

Regular inspections and pumping of your septic system prevent leaks that can release bacteria and nutrients into groundwater. Well-maintained systems protect both your water and your neighbors’ water.

Use the recommended amounts and timing for fertilizers, manure, or biosolids to reduce runoff. When excess nutrients reach water sources, they can harm water quality and aquatic ecosystems.

Apply only the amount needed for safety and store it properly to prevent runoff. Excess salt can build up in groundwater or surface water, affecting drinking water and the environment.

Avoid piling snow or de-icing chemicals near wells, waterways, or storm drains. As snow melts, chemicals can wash into water sources, potentially contaminating them.
