EPA Awards Nearly $8.5M in Research Grants to Ensure Cleaner and Safer
Drinking Water
WASHINGTON (Aug. 15, 2023) – Today, the U.S. Environmental Protection Agency
(EPA) announced $8,492,000 in grant funding to four institutions for research
on the occurrence and concentration of pathogens and disinfection by-products
and the environmental conditions favorable to their growth in drinking water
distribution systems.
“New strategies for monitoring and controlling contaminants in drinking
water will help ensure that science underpins the protection of our health and
our ecosystems,” said Chris Frey, Assistant Administrator for EPA’s Office
of Research and Development. “The research funded today will provide key
information for innovative scientific and technological solutions to improve
current drinking water infrastructure.”
Opportunistic pathogens (OPs) such as Legionella, mycobacteria, and
Pseudomonas can grow in drinking water systems and pose potential risks to
public health. The occurrence of these and other microbial pathogens is also
associated with contaminated storage facilities and other problems in water
distribution systems such as backflow and low-pressure incidents. If left
untreated, these contamination events can lead to outbreaks of
gastrointestinal and other waterborne illnesses. The disinfectants used to
control these pathogens can cause additional problems by reacting with natural
organic matter, bromide, and other contaminants to form disinfectant
by-products (DBPs), which also have the potential to be harmful to human
health.
The research announced today will improve our understanding of how to control
these contaminants and help inform water infrastructure management and
risk-mitigation practices to ensure cleaner drinking water for all Americans.
The following institutions are receiving awards:
University of Minnesota, Minneapolis, Minn., to develop strategies for
limiting exposure to OPs and DBPs and generate new data on OP and DBP
occurrences in U.S. water distribution systems, including understudied small
systems in rural Alaska that serve economically disadvantaged native
populations.
Michigan State University, East Lansing, Mich., to better understand and
predict occurrences of DBPs, OPs, and their associated health risk tradeoffs.
Project outcomes will support better evaluation, monitoring, and risk
management strategies in drinking water distribution systems across the U.S.
University of Texas, Austin, Texas, to conduct a nationwide study of
contaminants across a wide variety of drinking water distribution systems and
help identify occurrence patterns of OPs and DBPs. Research will demonstrate
how health risks are correlated with general water quality and distribution
system factors to inform strategies that will reduce risks to people from
drinking water.
Georgia Tech Research Corporation, Atlanta, Ga., to monitor the drinking water
microbiome and manage pathogen and DBP risks in drinking water storage and
distribution systems. The project will also assess pathogen and DBP impact on
the availability of safe water to inform appropriate health risk
interventions.
