Fact

Decaying vegetation and sediments transport heavy metals and phosphorous compounds that can become toxic and harm water quality.  Sedimentation also fills  waterways resulting in more severe flooding over time.

One gallon of oil can contaminate one million gallons of drinking water; or just one quart can contaminate 250,000 gallons of water.

Litter produces an obvious visual pollution which can physically damage animals and natural vegetation and can release substances  poisonous to natural systems when it breaks down.  Stormwater  drains in Sedona  do not filter many pollutants including trash.
