Geospatial Patterns of Antimicrobial Resistance Genes in U.S. Rivers and Streams
Citation:
Keely, S. Geospatial Patterns of Antimicrobial Resistance Genes in U.S. Rivers and Streams. EPA ORD Water Research Webinar Series, Cincinnati, Ohio, September 18, 2019.
Impact/Purpose:
This webinar presented how a stratified, probabilistic survey—National Rivers and Streams Assessment (NRSA)— was used to determine the national geospatial patterns of several antimicrobial resistance genes present in U.S. waters. NRSA is part of the National Aquatic Resource Surveys (NARS), which are collaborative programs between EPA, states, and tribes designed to assess the quality of the nation's coastal waters, lakes and reservoirs, rivers and streams, and wetlands using a statistical survey design.
Description:
Antimicrobial resistance (AR) is a serious human-health problem in the United States because each year 2 million individuals are infected with antimicrobial resistant bacteria (ARB) resulting in 23,000 deaths. Here we use a stratified, probabilistic survey to determine the geospatial patterns of antimicrobial resistance genes (ARG) and fecal pollution in 1.2 million kilometers of US rivers and streams.
