At 精品SM在线影片, we are fortunate to have beautiful waterways, including Boulder Creek, integrated into our campus ecosystem. However, keeping these waterways healthy requires our collective effort.

Boulder Creek is considered an impaired waterway by the state of Colorado due to excess amounts of Escherichia coli bacteria (E. coli). While Boulder Creek is not currently considered impaired by nutrient pollution, raising awareness about nutrients is key to help prevent future impairment.

Nutrient pollution: What is it and why should we care?

Nutrient pollution occurs when excess compounds of nitrogen and phosphorus enter our waterways, often from sources like fertilizers, pet waste and improperly disposed organic material. These nutrients can be washed off lawns and gardens during rainfall or irrigation, flowing directly into storm drains and, ultimately, into our stormwater systems. Once in the water, they can cause algal blooms, which deplete oxygen levels, harm aquatic life and degrade water quality.

E. coli contamination in Boulder Creek

In addition to nutrient pollution, E. coli, a common bacterium from multiple sources, also impacts Boulder Creek. Urbanization reduces the number of porous surfaces and increases contamination sources that wash into the storm sewer, promoting bacterial growth. The university is actively investigating and addressing the sources of E. coli in stormwater discharges.

How you can help reduce nutrient pollution and E. coli loading

• Fertilizer use: Avoid over-fertilizing lawns and gardens, and never apply fertilizers near storm drains.
• Organic waste: Properly dispose of lawn clippings, leaves听and other organic material instead of letting them wash into storm drains.
• Pet waste: Always clean up after your pets. Pet waste contributes to both bacteria and nutrients that pollute stormwater.
• Trash disposal: Place all garbage in waste containers, and avoid feeding wildlife, which can increase waste in waterways.
• Report issues: If you see illegal dumping or clogged storm sewer inlets on campus, contact Facilities Management at 303-492-5522.

As a large, eco-conscious community at 精品SM在线影片, we have a great opportunity to work together to protect our stormwater resources and contribute to the university鈥檚 sustainability goals. By adopting simple habits like cleaning up after pets, properly disposing of waste and being mindful of fertilizer use, each of us can make a positive impact.
