The major objective of this research was to determine the extent to which active uranium mining and milling operations in the grants mineral belt of west-central New Mexico contribute excess trace metals and radionuclides to Rio Puerco and Rio San Jose sediments. Subsidiary objectives include the determination of the modes of sediment movements in the Rio Puerco-Rio San Jose drainage systems and determination of the age of deposits along and adjacent to the modern drainage channels. Procedures used to make these determinations include (1) geomorphic evaluation of the fluvial transport and depositional system and evaluation of loci of sediment deposition along the drainages, (2) historical documentation of loci of deposition to aid in determining the age of sediments, (3) field sampling and sediment characterization, (4) laboratory characterization of grain size and mineralogy of sediment samples, (5) laboratory determination of trace metals and radionuclide concentrations in sediments, and (6) laboratory determination of ages of sediments using radioactive cesium-137 and lead-210.
