Testing the Health of the Wissahickon Creek-September 12th
Text Size: A A A

Turning the Wissahickon Creek green to test how healthy it is:

Environmental scientists from Temple University and The Academy of Natural Sciences of Drexel University are doing an experiment to investigate the health of the Wissahickon stream ecosystem.  During the month of September, we will be conducting several day-long stream tracer tests near Gwynedd Valley and Ambler.  The first test will be Tuesday, September 12th, in Ambler, starting between Morris Road and Lafayette Ave and traveling downstream toward Philadelphia. During the tracer test we add two non-toxic, fluorescent dyes into the Creek and track how that dye signal comes through further downstream. The tracers help us understand flowpaths within the stream and where stream metabolism occurs. The dyes that we are using are non-toxic and commonly used in environmental research and elsewhere (ex. coloring the Chicago River green for St. Patrick’s Day).  These tests are being conducted in consultation with the PA Department of Environmental Protection and are funded through a grant from the National Science Foundation.
