Two basic motives for treating wastewater Public health and protection of environment
the ability of the natural system to accept certain pollutants
Assimilative Capacity and render them benign or inottensive; pollution occurs
when this capacity is exceeded
The Great Stink London, 1800's, outbreak of cholera
Broad street pump handle incident, mapped cholera
John Snow
deaths
EPA formed by Nixon in 1970, 44 federal agencies
Title 40 CFR Subchapter D Part 136, (1977) Sets standards
of waste discharge into US water by industry. Also con-
tinues requirements to set water quality standards for all
contaminants in surface waters. It makes it unlawful for
Clean Water Act
any person to discharge any pollutant from a point source
into navigable waters, unless a permit is obtained. It also
recognizes the need for planning to address the critical
problems posed by nonpoint source pollution.
