Study Design & Sequence of Events Study Design
The objective of the study was to determine the principal sources of metals and acidity in the reach of Cement Creek, beginning upstream of Ohio Gulch and ending downstream of Topeka Gulch. This reach includes the Mayday Mine Dump on the West side of the stream and the Yukon Mine (a.k.a. Gold Hub Mine) on the East side of the stream. The injection site was located approximately 400 meters upstream of Ohio Gulch.
