Public Notice

July 28, 2014 

The Wind River Environmental Quality Commission, an agency of the Eastern Shoshone and Northern Arapaho Tribes (WREQC), under a US EPA-approved Quality Assurance Project Plan collected water samples from the Popo Agie River at the “Wyopo” Bridge about 1 mile downstream of the City of Lander. Consequently the samples displayed elevated levels of E. coli bacteria. Two single samples exceeded the Tribal Water Quality Standard of 235 cfu/100ml for primary contact recreation (activities which may include full body contact or ingestion of small quantities of water). WREQC is continuing to assess the situation and will collect weekly samples to establish a 30-day geometric mean at this location. At this time, the public is advised to use their best judgment when recreating in this area until additional results are available. Please contact Ryan Ortiz at the WREQC at 307-332-3164 for further information. Elevated levels of E. coli bacteria can be responsible for potentially dangerous gastro-intestinal illnesses. Symptoms of illness can be stomach cramps, bloody diarrhea, nausea/vomiting and low grade fever. If you are experiencing these symptoms, follow up with your physician.
