Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of methylene blue active substances by spectrophotometry
A method for the determination of methylene blue active substances in whole-water samples by liquid-liquid extraction and spectrophotometric detection is described. Sulfate and sulfonate-based surfectants are reacted with methylene blue to form a blue-colored complex. The complex is extracted into chloroform, back-washed with an acidified phosphate-based buffer solution, and measured against ext

Environmental factors used to subdivide the western Lake Michigan drainages into relatively homogeneous units for water-quality site selection
In 1991, the National Water-Quality Assessment (NAWQA) Program was fully implemented by the U.S. Geological Survey (USGS). The goals of the NAWQA program are to (1) provide a nationally consistent description of water-quality conditions for a large part of the Nation’s water resources; (2) define long-term trends (or lack of trends) in water quality; and (3) identify, describe, and explain, as pos

Geohydrology and vertical distribution of volatile organic compounds in ground water, Fischer and Porter Company Superfund Site, Warminster, Bucks County, Pennsylvania
The Fischer and Porter Company Superfund Site is underlain by sedimentary rocks of the Upper Triassic Stockton Formation, which consists of interbedded siltstone, very-fine grained to coarse-grained sandstone, and conglomerate in crudely defined, upward fining cycles. These rocks form a complex, heterogeneous, leaky, multiaquifer system comprised of a series of gently dipping lithologic units with

Water-resources investigations in Wisconsin, 1995
The statewide average precipitation of 30.66 inches for the 1994 water year was 96 percent of the normal annual precipitation of 31.79 inches for water years 1961-90. Average precipitation values ranged from 81 percent of normal in southeastern Wisconsin to 103 percent of normal in west-central Wisconsin (Pamela Naber Knox, UW-Extension, Geological and Natural History Survey, written commun., 1994

Ground Water Atlas of the United States: Segment 1, California, Nevada
California and Nevada compose Segment 1 of the Ground Water Atlas of the United States. Segment 1 is a region of pronounced physiographic and climatic contrasts. From the Cascade Mountains and the Sierra Nevada of northern California, where precipitation is abundant, to the Great Basin in Nevada and the deserts of southern California, which have the most arid environments in the United States, few

Ground Water Atlas of the United States: Segment 2, Arizona, Colorado, New Mexico, Utah
This chapter of the Ground Water Atlas of the United States describes the aquifers in Arizona, Colorado, New Mexico, and Utah. These four States, which comprise Segment 2 of this Atlas, are located in the Southwestern United States and extend from the rolling grasslands of the Great Plains on the east across the Rocky Mountains and Continental Divide to the desert basins of the Southwest. The 425,

Delineation of flooding within the upper Mississippi River basin — Flood of July 30, 1993, in Jefferson City and vicinity, Missouri
This report provides Missouri River flood-peak elevation data and delineates the areal extent of flooding in Jefferson City and vicinity, Missouri, for July 30, 1993. The July 1993 flood is compared with the Federal Emergency Management Agency's (FEMA) 100- and 500-year flood profiles. This report is one of a series of U.S. Geological Survey reports to document the flooding within the upper Missis

Delineation of flooding within the upper Mississippi River Basin, 1993 — Flood of June 29-September 18, 1993, in Iowa City and vicinity, Iowa
The hydrologic investigations atlas shows the areas in and around Iowa City, Iowa, that were flooded by the Iowa River in 1993. This map also depicts the Federal Emergency Management Agency (FEMA) 100-year flood boundaries. The drainage basin of the Iowa River at Iowa City received well over 100 percent of normal rainfall in June, July, and August, 1993. At the Cedar Rapids airport, located about

Hydrologic aspects of Hurricane Hugo in South Carolina, September 1989
Hurricane Hugo, with winds in excess of 135 miles per hour(mi/h), made landfall near Charleston, S.C., early on the morning of September 22, 1989. It was the most destructive hurricane ever experienced in South Carolina. The storm caused 35 deaths and $7 billion in property damage in South Carolina (Purvis, 1990).This report documents some hydrologic effects of Hurricane Hugo along the South Carol

Spatial and temporal trends of contaminants in eggs of wading birds from San Francisco Bay, California
Between 1989 and 1991, reproduction by black-crowned night-herons (Nycticorax nycticorax) and snowy egrets (Egretta thula) was studied at sites in San Francisco Bay. Eggs were collected from these and other bay sites and from South Wilbur Flood Area, a reference site in California's San Joaquin Valley. Eggs were analyzed for inorganic trace elements, organochlorine pesticides, and polychlorinated

Assessment of information on ground-water/surface-water interactions in the northern midcontinent
Ground-water/surface-water interactions are important to the hydrology of shallow aquifers, streams, lakes, and wetlands. Information on ground-water/surface-water interactions in the northern midcontinent was assessed. The ground-water/surface-water interactions in physiographic and climatic areas that contain many wetlands differed from the interactions in areas that consisted predominantly of a
