“The addition to the
biosphere of any
substance or agent (such
as heat) by human
activity at a rate
greater than that at
which it can be rendered
harmless by the
environment, and which
has an appreciable effect
on the organisms within
it.”NEXT

Point-Source Pollution
easy to identify
impacts are localized (smaller area)
simpler +/or easier regulation
Non point-source pollution
harder to identify
many sources from large area
may cross boundaries (different laws)

HIGH BOD = many organisms using O2
for respiration = low dissolved oxygen
(DO) = high pollutant levels, esp. nitrate
