Learn what impairs our lakes and streams! Understanding what causes water quality impairments is the first line of defense for any urban development. Local lakes and streams are impacted when excess sediment, nutrients, and bacteria are introduced into stormwater runoff. 

What can be done to improve stormwater quality on campus?

  • Report discharges to the storm sewer that are not comprised entirely of stormwater or when illicit dumping is observed. On City and East Campus you can report concerns to the EHS Pollution Reporter Tool or contact EHS. 
  • Picking up litter you see on campus.
  • Don't dump liquids, such as coffee or other drinks down the storm sewer.
  • Don't work on your vehicle in parking lots, where oil or other vehicle fluids can be incidentally released into the environment. 
  • Don't dump cleaning agents or paints or other materials into the storm sewer. 

What can be done to improve stormwater quality at home?

  • Use fertilizers sparingly. Use soil testing to understand what your yard needs and do not over-fertilize. Sweep hard surfaces of excess fertilizer to prevent from entering the storm sewer. 
  • Use the least toxic pesticides and herbicides. Consider reducing usage by spot treating instead of blanket treating. Do not over-apply and follow the label instructions.
  • Keep leaves, yard trimmings, trash, and other debris out of the storm sewer. Consider composting these items.
  • Wash vehicles at the carwash and prevent vehicle fluids, soaps, and sediment from entering the storm sewer.
  • Pick up after your pet.
