National water summary 1987: Hydrologic events and water supply and use National water summary 1987: Hydrologic events and water supply and use

Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the remainder of the withdrawals (72.7 percent)...

Geohydrologic systems in Kansas with emphasis on systems in Upper Cambrian through Lower Cretaceous rocks Geohydrologic systems in Kansas with emphasis on systems in Upper Cambrian through Lower Cretaceous rocks

This Hydrologic Investigations Atlas, which consists of a series of chapters, presents a description of (1) the physical frameworks and (2) the geohydrology of the principal aquifers and confining systems in Kansas. The report is the result of an investigation that has been made as part of the Central Midwest Regional Aquifer System Analysis (CMRASA), one of several major investigations...

Major geohydrologic units in and adjacent to the Ozark Plateaus province, Missouri, Arkansas, Kansas and Oklahoma: Ozark aquifer Major geohydrologic units in and adjacent to the Ozark Plateaus province, Missouri, Arkansas, Kansas and Oklahoma: Ozark aquifer

An investigation of the geohydrologic system in the Ozark Plateaus province (index map and Fenneman, 1938) has been made as part of the Central Midwest Regional Aquifer-System Analysis (Jorgenson and Signor, 1981), a major study that encompasses parts of 10 States. The study is one of several by the U.S. Geological Survey that are designed to increase knowledge of the flow regime and...

Source, extent, and degradation of herbicides in a shallow aquifer near Hesston, Kansas Source, extent, and degradation of herbicides in a shallow aquifer near Hesston, Kansas

Atrazine, alachlor, cyanazine, metolachlor, and metribuzin were detected in water from a domestic well completed in a shallow aquifer underlying the Harvey County Experiment Field near Hesston, Kansas. The study described in this report investigated the source, extent, and degradation of these five herbicides. Hydrogeologic analysis of the site enabled estimation of the degradation half...
