The Water Emergency Team is led by co-Principal Investigators SPH Assistant Professor in Global, Environmental, and Occupational Health (GEOH) Dr. Rachel Rosenberg Goldstein and Dr. Marccus D. Hendricks, associate professor of Urban Studies and (Environmental) Planning at UMD. WET is a joint venture between Goldstein’s Water Quality, Outreach, and Wellness (WOW) Laboratory and the Stormwater Infrastructure Resilience and Justice (SIRJ) Lab. WET was developed as a community-driven rapid-response to sewer overflows and backups in underserved African American communities in Baltimore and the surrounding region.
UPDATE: On Jan. 19, 2026, a large wastewater pipe broke and spewed sewage into the Potomac River in one of the largest wastewater spills in U.S. history. Since then, the group - in collaboration with the Potomac Riverkeepers Network - have been testing water and dirt samples for bacteria - including E. coli and S. aureus (staph) at both at the spill site and downriver. Learn more about initial testing results and analysis, and analysis of the sewer infrastructure failure that led to the spill:

Exposure to raw sewage from failing infrastructure can lead to negative health outcomes, distress, and feelings of disenfranchisement, particularly in marginalized urban communities. Sanitary sewer overflows (SSOs), the release of untreated sewage from a municipal sewer system, affect several cities around the world, with as many as 75,000 occurring each year in the United States. Baltimore experiences frequent SSOs and household basement backups due to aging and failing sewer and stormwater infrastructure. As a result, communities are persistently exposed to raw sewage, likely containing waterborne pathogens and possibly antibiotic-resistant (AR) bacteria. While AR bacteria have been identified in wastewater at wastewater treatment plants, no studies have comprehensively evaluated exposure to these pathogens from SSOs or backups, nor the impact of physical damage to the home and infrastructure on communities. This project addresses these knowledge gaps by developing a community-driven rapid response Water Emergency Team (WET) to respond to SSOs and backups in underserved African American communities in Baltimore and the surrounding region. WET will complete visual household inspections, conduct residential surveys and interviews about impacts and experiences with these events, collect water and surface swab samples from impacted indoor areas, and analyze samples for AR bacteria, reporting results back to the community. WET will work directly with community organizations and neighborhood associations throughout the project, including translating research findings into an outreach program with the goal of empowering affected communities and informing local policymakers. Climate change will only continue to stress the U.S.’s crumbling infrastructure, disproportionately impacting marginalized communities exposed to raw sewage. The Water Emergency Team has the expertise, experience, and community partnerships to address these issues, bringing national attention and visibility for the university and communities alike.
