      <abstract>This data set includes analysis of 38 sediment samples collected near the Old Yuma Mine.  The sediment samples were collected from tailings, waste rock, stream sediment, and background locations.  All samples were analyzed by a total digestion method, some by the USEPA 3050 method, and some were leached by the USEPA 1312 method.</abstract>
      <purpose>Samples were collected to assess concentrations of sediment near the Old Yuma Mine in samples related to mining activities as well as background samples.</purpose>
