National Pesticide Monitoring Program: Residues of organochlorine chemicals in freshwater fish, 1980–81 National Pesticide Monitoring Program: Residues of organochlorine chemicals in freshwater fish, 1980–81
The U.S. Fish and Wildlife Service analyzed residues of organochlorine chemicals in 315 composite samples of whole fish collected in 1980–81 from 107 stations nationwide as part of the National Pesticide Monitoring Program (NPMP). The mean concentrations of total DDT and allp,p′-ho-mologs exceptp,p′-DDT showed significant but small declines relative to mean concentrations before 1978–79...

Interactions among temporary and permanent meiofauna: Observations on the feeding and behavior of selected taxa Interactions among temporary and permanent meiofauna: Observations on the feeding and behavior of selected taxa
Meiofauna diets and behavioral patterns are relatively unknown despite the fact that in any system, predatory relationships and behavioral responses may play an important role in determining community structure. Therefore, observations on food preferences, feeding behavior, and encounter interactions of members of a meiofauna assemblage were made in the laboratory in dishes of natural...

Ground-water data for the alluvial, buried channel, Basel Pleistocene and Dakota aquifer in west-central Iowa Ground-water data for the alluvial, buried channel, Basel Pleistocene and Dakota aquifer in west-central Iowa
The purpose of this investigation was to determine the availability, quantity and quality of groundwater from three principal aquifers in West-Central Iowa, the alluvial, buried channel, Basal Pleistocene and the Dakota aquifers. Specific objectives were to: (1) determine the location, extent and the nature of these aquifers; (2) evaluate the occurrence and movement of groundwater...

Water resources of north-central Iowa Water resources of north-central Iowa
One of man's fundamental needs is water. Modern man needs both a safe and dependable supply of water to maintain his present economic, industrial, and cultural level. In order to use this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of water sources, and of the occurrence and potential of each source, needs to be gained. To provide...

National water summary 1984: Hydrologic events, selected water-quality trends, and ground-water resources National water summary 1984: Hydrologic events, selected water-quality trends, and ground-water resources
Water year 1984 was a year of extreme hydrologic conditions. For the third consecutive year, precipitation and resulting runoff were well above long-term averages in most of the Nation and as much as 400 percent above average in the Southwest. National flood damages during the year were the third highest in a 10-year period (1975-84) an estimated $3.5 to $4 billion. In many of the larger...

Hydrology of the alluvial, buried channel, basal Pleistocene and Dakota aquifers in west-central Iowa Hydrology of the alluvial, buried channel, basal Pleistocene and Dakota aquifers in west-central Iowa
A ground-water resources investigation in west-central Iowa indicates that water is available from alluvial, buried channel, basal Pleistocene, and Dakota aquifers. The west-central Iowa area includes Audubon, Carrol1, Crawford, Greene, Guthrie, Harrison, Monona, and Shelby Counties. Nine alluvial aquifers consisting of sand and gravel are in the valleys of the Little Sioux, Maple...
