Study Design & Sequence of Events

Study Design

The objective of the study was to determine the principal sources of metals and acidity in the upper reaches of Cement Creek, upstream of Gladstone. The injection site was located below Ross Basin and above the Mogul Mine. Synoptic samples were collected at various locations, starting just below the South Fork and continuing upstream to the injection site.
