region, known as the New Lead Belt, became one of
the largest lead-producing areas in the world. It con-
tinues to be a primary producer of lead with sec-
ondary production of zinc, and small quantities of
copper and silver (Brumbaugh et al, 2007). In order to
evaluate the impact of mining on this sparsely populated,
heavily forested, and hilly region, a number of surface-
water and aquatic life forms were examined. Samples
were collected from streams free of mining and milling
operations (control samples) and from contaminated
streams.
