Environmental Concerns

Non-Point Source Pollution

Most pollutants in our lakes and rivers come from multiple sources, known as non-point source pollution. As stormwater flows across the ground and pavement, it picks up contaminants such as motor oil, fertilizers, leaves, and garbage.

Non-point source pollution is the leading cause of water pollution in our rivers and lakes. It can harm fish and aquatic life, create unsafe swimming conditions, and litter our waterways and beaches.

Stormwater Pollution Prevention

Your actions on your property directly impact water quality in our ponds, rivers, and lakes. The following steps can help reduce stormwater pollution:

  • Limit chemical use on your lawn and garden. Pull weeds by hand when possible. If using fertilizer, choose one with no phosphorus (indicated by a "0" in the middle of the three-number nutrient label).
  • Compost yard waste and use a mulching mower. The City compost site is open most weekends from spring through fall.
  • Dispose of hazardous materials properly. Do not dump oil, chemicals, fertilizers, or other waste onto pavement or into storm drains. Take them to the Dakota County Eco-Site at 3365 South Highway 149 in Eagan.
  • Use a broom instead of a hose. Dry sweep driveways and walkways to prevent runoff into storm drains.
  • Pick up litter. Trash on the ground can enter storm drains and flow into lakes and rivers.
  • Maintain your vehicle. Repair leaks to prevent oil, grease, gasoline, antifreeze, and brake fluid from washing into storm drains.
  • Dispose of pet waste properly. Scoop, bag, and throw pet waste in the trash to prevent harmful bacteria from entering water systems.
  • Wash your car at a commercial car wash or on grass. This prevents soap and dirt from flowing directly into storm drains. Use a phosphorus-free soap.

Small changes in daily habits can help improve water quality in our community.
