Why was the data set created?

To determine the extent of contamination at the site, the investigation focused on answering the following questions: (1) What type of mine waste is present at the site? (2) What is the chemical composition of the mine-waste piles? (3) What is the acid-generating potential of the material? (4) Are potentially toxic trace metals leached from the waste? If so, are the metals leached in quantities that may contaminate soils and streams and have a deleterious effect on the environment? (5) How variable is the environmental impact among the various mine-waste piles? (6) Is any of the material geochemically similar to mine waste at the near-by Elizabeth mine, a Superfund site in the initial stages of remediation? This last question is important because if mine waste at the Ely mine is geochemically similar to the mine waste at the Elizabeth mine (Fig. 1), remediation technologies evaluated for the Elizabeth mine may be applicable to the Ely mine.
