Jeffrey S. Steuer, Sharon A. Fitzgerald, David W. Hall
1999, Water-Resources Investigations Report 99-4100
The distribution and transport of polychlorinated biphenyl (PCB) congeners were determined at various sites on Cedar Creek and its receiving stream, the Milwaukee River. PCB congener distributions were determined in the operationally defined dissolved phase, suspended-particle phase, and surficial bed sediments (0?2 centimeters depth). At most sites, the relative abundances...
Ground-water system, estimation of aquifer hydraulic properties, and effects of pumping on ground-water flow in Triassic sedimentary rocks in and near Lansdale, Pennsylvania
Lisa A. Senior, Daniel J. Goode

Estimating Concentrations of Road-Salt Constituents in Highway-Runoff from Measurements of Specific Conductance
Gregory E. Granato, Kirk P. Smith
1999, Water-Resources Investigations Report 99-4077
Discrete or composite samples of highway runoff may not adequately represent in-storm water-quality fluctuations because continuous records of water stage, specific conductance, pH, and temperature of the runoff indicate that these properties fluctuate substantially during a storm. Continuous records of water-quality properties can be used to maximize the information obtained...

1999, Water-Resources Investigations Report 99-4080
The goals of the National Water-Quality Assessment Program are to describe current water-quality conditions for a large part of the Nation's water resources, identify water-quality changes over time, and identify the primary natural and human factors that affect water quality. The lower Tennessee River Basin is one of 59 river...

1999, Water-Resources Investigations Report 99-4095
Five insecticide residues and 20 herbicide residues were detected in water samples collected from 50 shallow wells screened in the surficial sand and gravel aquifer in Suffolk County, Long Island in areas with known or suspected residues. Laboratory analytical methods with extremely low detection limits - from 0.001 to 0.2...
Ground-water quality and susceptibility of ground water to effects from domestic wastewater disposal in eastern Bernalillo County, central New Mexico, 1990-91
Paul J. Blanchard, Georgianna E. Kues
1999, Water-Resources Investigations Report 99-4096
Eastern Bernalillo County is a historically rural, mountainous area east of Albuquerque, New Mexico. Historically, the primary economic activity consisted of subsistence farming and ranching and support of these activities from small communities. During the last 40 to 50 years, however, the area increasingly has become the site of residential...
