Adequate water supply and good water quality are critical to the public's health and for disease prevention. The processes for design and management of municipal treatment facilities and private water systems are examined -- with attention to climate change impacts. Considerations of historical contaminants (lead, cholera and solvents) and emerging contaminants (PFAS, pharmaceuticals and algae) with regard to water treatment and sustainable solutions are emphasized. Water quality topics include standards and regulations and water quality analysis of drinking and surface waters. Social, political, and economic factors effecting water quality, treatment and access are discussed. Students are expected to participate in field sampling (during class time) in order gain useful skills. The course will conclude with historical and international perspectives on water resources and management.
