Effects of climatic change and climatic variability on the Thornthwaite moisture index in the Delaware River basin Effects of climatic change and climatic variability on the Thornthwaite moisture index in the Delaware River basin
The Thornthwaite moisture index is useful as an indicator of the supply of water in an area relative to the demand under prevailing climatic conditions. This study examines the effects of long-term changes in climate (temperature and precipitation) on the Thornthwaite moisture index in the Delaware River basin. Temperature and precipitation estimates for doubled-CO2 conditions derived...

Assessment of nonpoint-source contamination of the High Plains Aquifer in south-central Kansas, 1987 Assessment of nonpoint-source contamination of the High Plains Aquifer in south-central Kansas, 1987
Ground-water quality was assessed in a 5,000-square-mile area of the High Plains aquifer in south-central Kansas that is susceptible to nonpoint-source contamination from agricultural and petroleum-production activities. Of particular interest were agricultural chemicals, mainly atrazine, and oil-derived hydrocarbons, which might occur in association with brines that formerly were...

Integrating quality assurance in project work plans of the U.S. Geological Survey Integrating quality assurance in project work plans of the U.S. Geological Survey
The U.S. Geological Survey's objectives for including quality assurance procedures in a project work plan are to ensure that the quality of the data collected is defined and is appropriate for the objectives of the investigation. The data- quality information can be used in the interpre- tation of the data. A project work plan that includes quality assessment provides definable benefits...

Geohydrologic systems in Kansas; physical framework of the confining unit in the Western Interior Plains aquifer system Geohydrologic systems in Kansas; physical framework of the confining unit in the Western Interior Plains aquifer system
The purpose of this Hydrologic Investigations Atlas is to provide a description of the geohydrologic systems in Upper Cambrian through Lower Cretaceous rocks in Kansas. This investigation was made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one of several major investigations by the U.S. Geological Survey of regional aquifer systems in the...

A reconnaissance study of herbicides and their metabolites in surface water of the midwestern united states using immunoassay and gas chromatography/mass spectrometry A reconnaissance study of herbicides and their metabolites in surface water of the midwestern united states using immunoassay and gas chromatography/mass spectrometry
Preemergent herbicides and their metabolites, particularly atrazine, deethylatrazine, and metolachlor, persisted from 1989 to 1990 in the majority of rivers and streams in the midwestern United States. In spring, after the application of herbicides, the concentrations of atrazine, alachlor, and simazine were frequently 3-10 times greater than the U.S. Environmental Protection Agency...
