This arc and point data set contains streamflow-measurement sites and reaches indicating streamflow gain or loss under base-flow conditions along Republican River tributaries in Nebraska during April 28 to May 1, 1980 (U.S. Geological Survey, 1981). The streamflow measurements were made to obtain data on ground-water/surface-water interaction. Flow was observed visually to be zero, was...

This arc and point data set contains streamflow-measurement sites and reaches indicating streamflow gain or loss under base-flow conditions along Republican River tributaries in Dundy and Chase Counties, Nebraska during July 14 to 18, 1975 (U.S. Geological Survey, 1976). The streamflow measurements were made to obtain data on ground-water/surface-water interaction. Flow was observed...

This arc and point data set contains streamflow-measurement sites and reaches indicating streamflow gain or loss under base-flow conditions along Republican River tributaries in Dundy and Chase Counties, Nebraska during October 6 to 8, 1975 (U.S. Geological Survey, 1977). The streamflow measurements were made to obtain data on ground-water/surface-water interaction. Flow was observed...

This arc and point data set contains streamflow-measurement sites and reaches indicating streamflow gain or loss under base-flow conditions along Republican River tributaries in Dundy and Chase Counties, Nebraska during May 19 to 20, 1975 (U.S. Geological Survey, 1976). The streamflow measurements were made to obtain data on ground-water/surface-water interaction. Flow was observed...

A network of 74 randomly distributed domestic water-supply wells completed in the central High Plains aquifer was sampled and analyzed from April to August 1999 as part of the High Plains Regional Ground-Water Study conducted by the U. S. Geological Survey National Water-Quality Assessment Program to provide a broad-scale assessment of the ground-water-quality in this part of the High...

A detailed ground-water sampling plan was developed and executed for 64 monitoring wells in the city of Independence well field to characterize ground-water quality in the 10-year zone of contribution. Samples were collected from monitoring wells, combined Independence well field pumpage, and the Missouri River at St. Joseph, Missouri, from 1998 through 2000. In 328 ground-water samples...

We thank Ericson et al. (1) for their careful review and thoughtful comments on the synthetic hormone data presented in our recent publication summarizing the results from the USGS nationwide reconnaissance for pharmaceuticals and other organic wastewater contaminants (2). Their efforts have helped raise the awareness of the difficulties in accurately measuring these compounds at the low

We concur with the response of Eckel to our recent publication in this Journal (1). As the author notes, the topic of emerging contaminants is currently receiving extensive media coverage and scientific notice, but there are earlier reports that foreshadow this current interest. Eckel’s comment regarding the detection of pharmaceuticals and other organic wastewater contaminants (OWC) at...

The effects of irrigation canals and the North Platte River on ground-water movement and quality in an irrigated alluvial valley, western Nebraska, were evaluated using environmental tracers. The results indicated that most of the ground water in the alluvium was derived from the North Platte River and generally was less than 30 years old. Ground-water-recharge rates varied substantially...
