A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program . The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch.
“We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.”
Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.Read More
Springfield, Ohio, a college town of 60,000 in southwestern Ohio, sits on the confluence of the Mad River and Buck Creek. Springfield’s streams are as much a part of the city as is Wittenberg University. The streams and the university’s brick infrastructure stand as a constant backdrop to the action of the community but do not often draw attention themselves.
Over the next year, however, Springfield will be paying close attention to its waterways in an effort to eliminate illegal discharges.

Since 2003 harmful bacteria Escherichia coli (E. coli) levels have created a health risk to recreational users in Boulder Creek. Boulder Creek has been designated as an impaired stream and is not meeting an EPA health-based water quality standard.
Concentrations of E. coli increase from the mouth of Boulder Canyon to the University of Colorado-Boulder and beyond based upon data collected by the City of Boulder according to information published by the CU Independent and the Boulder Camera . EM spoke to environmental engineer Art Hirsch of the Boulder Waterkeeper , who is advocating for greater accountability from all entities that own property abutting the stream.
