1994, Open-File Report 94-377
Hydrologic data collected during October 1, 1991, through September 30, 1992, in the Puerco River Basin, Western New Mexico, are summarized. The effects of uranium mining and a 1979 tailings pond spill, in combination with naturally occurring and potentially hazardous trace elements, have created a concern that surface water and...
Effects of ground-water chemistry and flow on quality of drainflow in the western San Joaquin Valley, California
John L. Fio, David A. Leighton
1994, Open-File Report 94-72
Chemical and geohydrologic data were used to assess the effects of regional ground-water flow on the quality of on-farm drainflows in a part of the western San Joaquin Valley, California. Shallow ground water beneath farm fields has been enriched in stable isotopes and salts by partial evaporation from the shallow...
