“Non-point-source” or NPS pollution is pollution that cannot be traced to a single-source outfall such as a factory pipe discharging into the river. Examples of non-point-source pollution include stormwater runoff from lawns, roads, parking lots, building sites, and agricultural fields. This runoff can contain petroleum products, salt, animal waste, fertilizers, pesticides, heavy loads of sand and silt, or other contaminants. Failing septic systems or other contamination of groundwater can also contribute to NPS pollution.
Since the Clean Water Act went into effect, most point-sources of pollution have been identified and regulated. Their contribution to river pollution has decreased dramatically. NPS pollution is a much harder problem to solve, because the solution depends on individuals deciding to change the way they do things.
What goes into a storm drain may straight into a river, or may enter a river via a sewage treatment plant. EITHER WAY, most pollutants are not removed! To reduce the strain on storm drains…
Let gutter outflow soak into the ground, or collect it in rain barrels.
This discourages geese from loitering, too.
