Abstract
Lead has been mined in the Old Lead Belt region of southeastern Missouri, USA since the early 1700s. Mining operations ceased totally in 1972. Since no other major industries were associated with the region, an investigation was initiated to study the long-term environmental effects of lead mining activities on the water quality sediments and biota otarea receiving streams. The principal study area was Flat River Creek,. which drained the major mining operations of the region.
