Groups work to track E. coli in rivers
|
In late August, San Juan Watershed Group Coordinator Alyssa Richmond reached out across the San Juan River using a long pole as it flowed through the Fruitland area and scooped up water. This water was transferred into a bottle that was capped to be sent to a lab in Florida where it will be analyzed to see how much bacteria like E. coli is coming from human waste. Human waste can lead to high levels of E. coli in rivers and the section of the San Juan River where the watershed group collected samples is listed as impaired for the bacteria. That means if people were to ingest the raw water it could make them sick. E. coli is one of the top three causes of water impairment in New Mexico, according to the New Mexico Environment Department’s 2020-2022 integrated report, and agencies throughout the state are working to address the bacteria contamination.
E. coli in the water can come from numerous sources, including leaking septic tanks, livestock, wildlife and pets.
Efforts are underway on both the San Juan River in northwest New Mexico and the Rio Grande in Albuquerque to test how much E. coli is coming from human waste.
