Soap contains phosphorous which can use up dissolved oxygen in the water. This is harmful to fish and other wildlife. Washing your car on a porous surface prevents the water from running out into the street and eventually down the storm drain. When you wash your car at a carwash, the water is collected and treated before going into the river.
Though leaf litter may seem organic and harmless, leaves are a major source of storm water pollutant. Leaves, grass clippings, prunings and lawn sediments create a high nutrient load leading to algae, rapid decay and depleted oxygen levels in the water. Instead of blowing them into the gutter, rake up leaves for disposal or create a healthy compost or mulch.
Fertilizers often contain synthetic chemicals as well as a very high amount of nutrients. These nutrients run off of our lawn when it rains, washing high amounts of phosphorus and nitrates into our river. This creates an environment where oxygen is depleted from algae and bacteria, and aquatic wildlife can no longer survive.
Rain and melting snow can wash pollutants from pet waste directly into the storm drain. When pet waste is washed into the Colorado River, it absorbs oxygen and releases ammonia. Overly fertile water becomes cloudy, green, unattractive and creates an unsafe environment for local wildlife. Most importantly, pet waste can carry diseases which could make water unsafe for contact.
