The Puerco River is an ephemeral stream that received effluent from uranium-mine dewatering operations from the 1950's until 1962 and from 1968 until mining ceased in 1986. Flow and water-quality relations between the Puerco River and the alluvial aquifer underlying it were investigated at a site near Chambers. Data collection included installing and sampling nine monitor wells and two drive points; monitoring stage and sampling surface water; and slug testing wells. The stream recharges the alluvial aquifer during periods of flow and the streambed is a location of ground-water discharge by evapotranspiration during periods of no flow. Discharge by evapotranspiration may exceed recharge thus reducing the potential for contaminant movement away from the river by advective transport. Geochemical modeling indicates that uranium minerals are undersaturated in the range in Eh observed. A +0.84 correlation was calculated relating dissolved uranium concentration to depth in monitor wells suggesting the stream is a source of uranium to the alluvial aquifer.

Dissolved noble gas concentrations in Canadian Shield groundwaters from various depths of the Miramar Con Mine, Yellowknife, were examined for paleotemperature information and isotopic ratios. A high-vacuum stainless steel line with reactive gas gettering, isotope spike dilution and quadrupole mass spectrometer was constructed, tested and calibrated prior to sample analysis. In addition to noble gases, groundwater flow rates and formational pressures, as well as the major ions, stable isotopes and tritium values, were also measured. Data collected on flow rates and formational pressures was compared to that published by Intera Consultants Ltd. (1997). Trends indicate an almost universal decline in both parameters over the four year period, reflective of changing mine conditions. The major ions in solution are represented primarily by Ca, Na, Cl, SO 4, and HCO3, at shallow depths. In the deep subsurface, Ca, Na, and Cl become the dominant species, forming a Ca-Na/CI brine characteristic of the Canadian Shield that reaches a TDS of 304 g/L. (Abstract shortened by UMI.)
