Occurrence of pesticide residues in four streams draining different land-use areas in Pennsylvania
Samples of water, bed material, fish, and soil were collected in four small drainage basins in Pennsylvania in 1969-71 and analyzed to determine the concentrations of chlorinated-hydrocarbon insecticides. Water samples only were also analyzed for phenoxy-acid herbicides. Each basin studied represents a predominant land-use classification—forested, general farming, residential, and orchard farming.

Digital model simulation of the glacial-outwash aquifer at Dayton, Ohio
Dayton, Ohio and its environs obtain most of their water from wells which penetrate highly productive glacial-outwash deposits underlying the Great Miami River and its tributaries and receive recharge by induced streambed leakage. Combined municipal and industrial use of ground water in the 90-square-mile area has increased from about 180 cubic feet per second in 1960 to nearly 250 cubic feet per

Stream reconnaissance for nutrients and other water-quality parameters, Greater Pittsburgh Region, Pennsylvania
Eighty-five stream sites in and near the six-county Greater Pittsburgh Region were sampled in mid-June 1971 in mid-October 1972. Data are reported for 89 sites because 4 substitute sites were sampled in the second period. Drainage areas of the basins sampled ranged from 4.1 to 19,5000 square miles (10.6 to 50,500 square kilometres). The chemical analyses included constituents of three general clas

Water-quality assessment of the Indiana Dunes National Lakeshore, 1973-74
The Indiana Dunes National Lakeshore is underlain by unconsolidated lake and glacial deposits which have been divided into three units. Unit 1 is comprised mostly of sand and, in the western part of the National Lakeshore, is capable of yielding more than 500 gallons per minute (32 litres per second) to properly constructed wells. Unit 2, a silt till below unit 1, has little potential as a source

An introduction to the processes, problems, and management of urban lakes
Lakes are bodies of water formed in depressions on the earth's surface, and as such, act as depositories for a variety of chemical and biological materials. The study of lakes has become increasingly prevalent in recent years. Lakes are a valuable resource, and their multiple uses have made them susceptible to water-quality problems such as algal blooms, sediment deposition and fish kills. These p
