water pollution - Answers -The impairment of water for any of its beneficial uses by
anthropogenic alterations of water quality
Whats the intent and function of the Clean Water Act in addresing issues of water
quality - Answers -to maintain the physical, chemical, and biological quality of surface
waters, seawater, and groundwater. It puts environmental and human health ahead of
economics

agricultural, energy, transportation, industrial, maintenance of ecosystem structure and
function, recreation, waste removal
Describe the NPDES permit program under the CWA in terms of its intent and function -

management program requires:
- a reliable method to define impaired waters
-Appropriate water quality standards and realistic beneficial uses
-mathematical models that include estimated nonpoint inputs
-feasible guidelines for setting allocations among contaminant contributors
-Reevaluation of NPEDS (discharge) permits
What are the leading sources of surface water pollution and sources of each type -
Answers --Agricultural: toxicants, nutrients, pathogens, organic matter, thermal, solids,
habitat destruction, and introduced species
-Domestic: pathogens, organic matter, solids, nutrients, toxicants
-Industrial: toxicants, thermal, organic matter
