Determining nonpoint source pollution is important in eliminating it. All detergents destroy the external mucus layers that protect fish from bacteria and parasites. They also lower the water's surface tension, making pesticides and chemicals more easily absorbed by the fish.
Some detergents contain phosphates that promote algae growth.
When algae decomposes, it uses up the available oxygen of aquatic life. Wash car at a car wash that is connected to sanitary sewer lines Silt and sediment from construction sites Sediment collects in drinking water reservoirs, leaving less room for water storage. Innovative and site-specific BMPs Stricter monitoring and education programs Cleared vegetation, tree trimmings, grass clippings, leaves, and acorns The debris clogs storm sewers, which increases the risk of flooding. Large collections obstruct water flow and cause creek bank erosion. As this organic matter decomposes, it uses up the oxygen intended for aquatic life survival.
