Description:   Sediment cores were collected and analysed from Benson Lake, which had for a time been receiving an input of pyrite-rich mine tailings, and Keogh Lake, which had not. Solid phase element analyses and dissolved metals and sulphate determinations were made on sediment samples and pore waters. It was determined that there was no efflux of Zn, Pb or Cd to the overlying waters of the lake basins.
Notes: "An Acid Drainage Task Force project in contribution to MEND."
