Molecular and isotopic tracers used to examine sources of organic matter and its incorporation into the food webs of San Francisco Bay
Multiple indicators (Chl a, C : N ratios, [δ13C]POC, and two classes of lipid biomarker compounds- sterols and phospholipid ester-linked fatty acids) were used to evaluate spatial and temporal variations in the origin of particulate organic matter (POM) in the San Francisco Bay (SFB) estuary. Comparisons were made between the northern and southern subestuaries of SFB, as well as along the salinity

Salinity in surface water in the Red River of the North basin, northeastern North Dakota
Saline ground-water discharge from bedrock aquifers collects in wetlands that drain into tributaries of the Red River of the North (Red River). The Turtle, Forest, and Park Rivers are the major contributors of salinity to the Red River. These three rivers drain areas of wetlands affected by ground-water discharge from bedrock and by direct evapotranspiration. This report describes the effect of tr

Statistical summaries of streamflow data for selected gaging stations in Idaho and western Wyoming through September 1990 — Volume 2: Gaging stations with 5 to 9 years of record or that measure discharge from springs
This volume presents statistical summaries of streamflow data for 76 gaging stations with 5 to 9 years of continuous record, or with records of discharge measurements from springs, through September 1990. The gaging stations are located in Idaho and western Wyoming. Some of the gaging stations at which spring discharge is measured have 10 or more years of record. Volume 1 presents statistical summ

Water-quality characteristics of streams in the Treyburn Development area of Falls Lake watershed, North Carolina, 1988-93
Treyburn is a 5,400 acre planned, mixed-use community located in the Falls Lake watershed in the upper Neuse River Basin of North Carolina. From February 1988 through 1993, hydrologic-data were collected at 17 study sites in or near the Treyburn development to compare the effects of varying types of land-use development on the water-quality of streams flowing in or near the development. The collec

Sediment oxygen demand in the lower Willamette River, Oregon, 1994
An investigation of sediment oxygen demand (SOD) at the interface of the stream and stream bed was performed in the lower Willamette River (river mile 51 to river mile 3) during August, 1994, as part of a cooperative project with the Oregon Department of Environmental Quality. The primary goals of the investigation were to measure the spatial variability of SOD in the lower Willamette River and to

Geochemical and hydrologic controls on phosphorus transport in a sewage-contaminated sand and gravel aquifer near Ashumet Pond, Cape Cod, Massachusetts
The disposal of secondarily treated sewage onto rapid infiltration sand beds at the Massachusetts Military Reservation, Cape Cod, Massachusetts, has created a sewage plume in the underlying sand and gravel aquifer; the part of the\x11sewage plume that contains dissolved phosphorus extends about 2,500 feet downgradient of the sewage-disposal beds. A part of the plume that\x11contains nearly 2 milli

Analysis of nutrient and ancillary water-quality data for surface and ground water of the Willamette Basin, Oregon, 1980-90
An analysis of historical water-quality data for surface and ground water collected in the Willamette and Sandy River Basins during the 1980-90 water years was performed. For surface water, most data were concentrated at sites on the main stem Willamette River or near the mouths of major tributaries. All seasons were represented. Data for nitrogen and phosphorus species were readily available, but

Use and occurrence of pesticides in the Apalachicola-Chattahoochee-Flint River basin, Georgia, Alabama, and Florida, 1960-91
The Apalachicola-Chattahoochee-Flint (ACF) River basin was one of the first 20 study units selected in 1991 by the U.S. Geological Survey for its National Water-Quality Assessment (NAWQA) program. Because pesticide contamination of surface water and ground water is a concern nationwide, a major emphasis of the NAWQA program is to examine the occurrence and distribution of pesticides in the water r

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
