Various forms of
organic matter may be carried by storm water in urban areas.
Decomposition of this material by organisms in the surface waters
result in depleted oxygen levels. Low levels of dissolved oxygen severely impact water quality and
life within surface waters.
Sources of organic matter include leaking septic systems, garbage,
yard waste, etc.
Debris
such as plastic bags, six-pack rings, bottles, and cigarette butts
are not organic matter. However, this type of debris can be washed into the water and can choke, suffocate or disable
aquatic life, including ducks, fish, turtles, and birds.
