Microbial source tracking for streams in Scott County, Iowa, 2023

공공데이터포털

Surface water samples (n = 33) were collected in fall of 2023 at stream sites in Scott County Iowa, USA and were analyzed for microbial source tracking markers by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Microbial source tracking markers identify fecal sources of contamination by detecting microbes that are specific to certain animals. Cooperators include Partners of Scott County Watersheds, Prairie Rivers of Iowa, and U.S. Department of Agriculture-Agricultural Research Service.

Microbial analyses of water from private wells in southwestern Wisconsin, 2019 to 2020.

공공데이터포털

Private wells (n = 138) were sampled by large- and small-volume sampling methods in Grant, Iowa, and Lafayette Counties, Wisconsin, USA in 2019 and 2020. Well water samples were analyzed for microorganisms by quantitative polymerase chain reaction at the Laboratory for Infectious Disease and the Environment (LIDE). Gene targets for viruses, bacteria, and protozoa were analyzed, including pathogens and microbial source tracking markers. Data were collected to characterize microbial contamination of private well water to better understand water quality and potential causes of contamination. Collaborators include U.S. Department of Agriculture-Agricultural Research Service; Wisconsin Geological and Natural History Survey; and Grant, Iowa, and Lafayette Counties, Wisconsin.

Groundwater and surface-water samples were collected and analyzed for microbial source tracking markers to identify the primary sources of fecal bacteria at a Lake Michigan beach in Northwestern Indiana.

Concentrations of microbial source tracking markers in cattle fecal samples, western Colorado, 2023

공공데이터포털

The U.S. Geological Survey is investigating sources of fecal bacteria in streams in the Grand Valley of western Colorado by using quantitative polymerase chain reaction microbial source tracking (MST) markers. The CowM2 MST marker was not detected in water-quality samples collected in 2022, which raised questions about the use of the marker for investigations in western Colorado. The presence or absence of bacteria associated with MST markers can be affected by geographic location, animal health, and diet. Known-source cattle fecal samples were collected in the Grand Valley to determine the presence or absence of the CowM2 marker in the feces of local cattle. A total of five samples were collected, representing herds grazing on public lands and local farms.
