Wastewater Infrastructure: Overview, Funding, and Legislative Developments [May 22, 2018] [open pdf - 809KB]
"Waste discharges from municipal sewage treatment plants into inland and coastal waters are a significant source of water quality problems throughout the country. Pollutants associated with municipal discharges include nutrients (which can stimulate growth of algae that can deplete dissolved oxygen or produce harmful toxins), bacteria and other pathogens (which may impair drinking water supplies and recreation uses), and metals and toxic chemicals from industrial and commercial activities and households. The collection and treatment of wastewater remains among the most important public health interventions in human history and has contributed to a significant decrease in waterborne diseases during the past century. Funding these systems continues to be of interest to federal, state, and local officials and the general public."
