Quality of a River - Water Quality
Status (pg 2 of 2)
Reduction in pollutant
loads were achieved through use of the following
key tools that originated from the Clean Water
- Section 319 to address nonpoint
sources, such as farmland and forestry runoff,
through planning, assessment and grants.
- Section 404 to regulate dredging
or filling of wetlands and other waterways.
- Section 401 to require federal
agencies to obtain certification from the state,
territory, or Indian tribes before issuing
permits that would result in increased pollutant
loads to a water body.
- State revolving funds for loans
to control municipal point and nonpoint pollution
- The development of a total
maximum daily load (TMDL) for impaired waters.
TMDLs determine what level of pollutant load
would be consistent with meeting water quality
- Section 402, National Pollutant
Discharge Elimination System (NPDES) permit
program to control point sources. Discharge of
stormwater from municipalities and construction
sites is included in this program.
Although the Clean Water Act has been a major
success in addressing point source pollution in
aquatic systems, nonpoint sources remain our
biggest challenge. Because of their diffuse nature,
financial disincentives, and lack of regulatory
authority, solving nonpoint source pollution will
require the combined efforts of each of our
individual choices and actions.
