Project Overview
Harnessing the trillion-dollar infrastructure of U.S. wastewater treatment plants, One Water One Health utilizes a technology called wastewater-based epidemiology (WBE) to pinpoint harmful chemicals in communities across America and halt their environmental and human impacts. The team envisions a nationwide wastewater monitoring network that would provide near real-time information on the use of toxic chemicals. By sampling community wastewater, the method adapts existing infrastructure to quickly build an early detection system for environmental stressors. These “pollution observatories” would allow the team to study the behavior of pollutants, identify problematic persisting chemicals, and formulate appropriate interventions. One Water One Health’s tools are particularly useful for underserved communities that suffer from environmental injustice. Depending on the number of treatment plants in a given city, for example, toxic inventories and exposures can be obtained on a neighborhood scale at very low cost—a type of analysis that’s economically impractical using traditional methods. Through their approach, the team has already discovered that two antimicrobial chemicals were overlooked environmental pollutants. (Both substances have since been banned from the U.S. market.) By alerting residents to risky chemicals in their communities in near real-time, One Water One Health can avert catastrophic health crises while equipping citizens with new tools to advance environmental equity.
