Microbial Source Tracking and Escherichia coli Monitoring in the Rio Grande in the South Valley, Albuquerque, New Mexico

Science Center Objects

The Rio Grande, in southern Albuquerque, is an impaired reach for bacteria. Escherichia coli (E. coli) bacteria are elevated in this reach of the Rio Grande even without stormwater present, during what is referred to as “dry season”. Samples will be collected over a range of flows including during the dry season (November 1st-June30th). Water samples will be analyzed for E. coli and microbial source-tracking markers, and bottom sediments will be analyzed for E.coli and markers.

Water and sediment samples for bacterial analysis will be collected from five locations along the Rio Grande between the USGS gages at Central Avenue, in Albuquerque, to the northern border of the Isleta Pueblo at the I-25 bridge. Sampling will continue through September 30, 2021.
