“What’s in the Water? Results from E.coli and Dye Tracing Investigations of Big Creek”, Teresa Turk, April 25, 5:30 p.m. Boone Co. Library
April 25, 2017 @ 5:30 pm - 6:30 pm
Escherichia coli (E. coli) bacteria normally live in the intestines of humans and warm blooded animals. Some E. coli are pathogenic and can cause illness, either diarrhea or other illness outside of the intestinal tract. Testing for E. coli on primary contact streams where people recreate by swimming or have similar water contact activities where a high degree of bodily contact, immersion and ingestion are likely is conducted throughout the state primarily by the Arkansas Department of Environmental Quality (ADEQ). ADEQ sets E. coli limits for primary contact during the year.
In 2012, a 6500 head swine confined animal feeding operation called C&H Hog Farm was permitted by ADEQ approximately six miles upstream from the confluence with the Buffalo National River. Citizen scientists began conducting dye tracing studies and collecting water samples to test for E. coli in close proximity to manure application fields and manure holding ponds. This talk will discuss the results and implications from these investigations.
Teresa Turk is an Arkansan, growing up in Little Rock and Texarkana. She received her BS in Zoology and MA in Anthropology at the University of Arkansas-Fayetteville. Upon completion of her Master’s degree, she headed west to Alaska and started working in the Bering Sea on board Soviet factory trawlers. She returned to school and received her MS in Fisheries Science from the University of Washington. Eventually this turned into a 25 year career as a fisheries scientist where she retired from NOAA in 2012. Since returning to Fayetteville, Teresa has started her own environmental consulting company and is part of a research team investigating the C&H hog operation in Mt. Judea. In her spare time she is making documentaries about Arkansas and its unique folk.
