Non-point Souce Pollution of Onondaga Lake

Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage or hydrologic modification. The term "nonpoint source" is defined to mean any source of water pollution that does not meet the legal definition of "point source" in section 502(14) of the Clean Water Act.

Non-point source (NPS) pollution may be a

strange-sounding term to many of us, but it’s an

ongoing situation that’s actually quite familiar to

all of us.

It refers to water pollution that doesn’t

come from a single, identifiable source or point

such as a discharge pipe into a body of water.

Instead, non-point pollution originates from

many sources, spread out over a large area and is

one of the pollution problems affecting Onondaga

Lake.
