Effects[edit]
To date, the water quality goals stated by Congress in the 1972 act have not been achieved by American society:
"to make all U.S. waters fishable and swimmable by 1983;"
"to have zero water pollution discharge by 1985;"
"to prohibit discharge of toxic amounts of toxic pollutants".[76]:1
More than half of U.S. stream and river miles continue to violate water quality standards.[77]
One study finds that "most types of water pollution declined [over the period 1962-2001], though the rate of decrease slowed over time... Our finding of decreases in most pollutants implies that the prevalence of such violations was even greater before the Clean Water Act." Several studies have estimated that the costs of the CWA (which include the Title II construction grants program) are higher than the benefits. An EPA study had similar findings, but acknowledged that several kinds of benefits were unmeasured.[76]:2
