Drinking Water and Wastewater Infrastructure Science Team Active
The Team Studies Toxicants and Pathogens in Drinking Water
To understand if and when humans are exposed
The Team Studies Toxicants and Pathogens in Streams
To understand if and when wildlife are exposed
The Team Studies Toxicant and Pathogen Sources and Movement
The Team Develops Tools to Understand Health Effects
The team studies toxicants and pathogens in water resources from their sources, through watersheds, aquifers, and infrastructure to human and wildlife exposures. That information is used to develop decision tools that protect human and wildlife health.
Americans rely on treatment of drinking water and wastewater, and the maintenance of water distribution infrastructure to assure safe water supplies for the public and wildlife. New chemicals are manufactured and used every day. Populations grow and demographics shift. Treatment, conveyance and plumbing infrastructure ages, and new technologies are developed to detect contaminants (toxicants and pathogens) at low levels. Consequently, questions arise about the health effects of exposure to contaminants indivually or in complex mixtures.
The US Geological Survey’s Drinking Water and Wastewater Infrastructure Science Team provides information on processes that affect contaminants as they move from naturally occurring and human-caused sources through aquifers, aquatic environments, and infrastructure. This comprehensive understanding of contaminant profiles from source to exposure is used to develop decision tools to economically, effectively, and efficiently reduce wildlife or human exposure and associated health risks.
The Team prioritizes science in underserved urban and rural agricultural communities and in tribal nations, which are disproportionally impacted by geologic and climatic events, by drinking-water source limitations and resultant dependence on water-reuse and unregulated/unmonitored private-wells.

Human-use pharmaceuticals in urban streams link aquatic-ecosystem health to human health.
