Poorly treated or untreated runoff, affects the water quality and the aquatic life in the local streams in a negative way, then the rivers which they feed, and then ultimately the Chesapeake Bay (Polluted Runoff). When it rains and the rain lands in a metropolitan or rural area, where watertight surfaces are common, the water flows into the storm drains with all the toxins it carries, this is the grey funnel. Naturally the water would either evaporate or slowly absorb into the ground, this is the green filter. The Chesapeake watershed contains forested buffers, wetlands, meadows, and farmland that soaks up and filters the nutrients. When the rain falls in a grey funnel area, most nitrogen and phosphorus pollution comes from sewage treatment plants, animal feeds lots, and polluted runoff from cropland, urban, and suburban areas. Also, air pollution from vehicle exhaust and industrial sources contribute about one-third of the nitrogen pollution (Nitrogen).
