Report issued by the U.S. Bureau of Mines discussing mineral materials of the Ohio River Basin. As stated in the abstract, "this study is a survey of supply and demand for minerals, metals, alloys, and compounds used by the chemical industries in the Ohio River Basin area of Ohio, Pennsylvania, and West Virginia during 1967" (p. 1). This report includes maps, tables, and illustrations.

From purpose and scope: This report provides basic information on the ground-water resources of Chester County, Pennsylvania, which is an area of about 760 square miles (1970 meters) in southeastern Pennsylvania. It discusses the availability and quality of the water in the water-bearing units in the county and the relation of the ground water to surface water.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Scranton quadrangles including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Newark quadrangles including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

From abstract: This data report presents preliminary results of ground water, stream sediment, and stream water reconnaissance in the National Topographic Map Series (NTMS) Williamsport 1° x 2° quadrangle.

Report issued by the U.S. Bureau of Mines discussing mine reclamation at Moraine State Park in Pennsylvania. As stated in the introduction, "this Bureau of Mines report has been prepared to provide the general public, private industry, and Federal and State Governments with current surface mine reclamation data on the methods and costs of a reclamation project where project specifications required that the disturbed lands be returned to their original contour" (p. 1). This report includes maps, tables, illustrations, and photographs.

This report presents preliminary results of ground water, stream sediment, and stream water studies in the Harrisburg quadrangle in Pennsylvania.

Final report documenting a high-sensitivity airborne radiometric and magnetic survey of the Williamsport quadrangle including the survey description, specifications, data processing methods, interpretation methods, and regional geologic review.

From abstract: The geochemical dispersion of uranium has been investigated near sedimentary uranium prospects in eastern and north-central Pennsylvania.

Abstract: Eighty-five stream sites in and near the six-county Greater Pittsburgh Region were sampled in mid-June 1971 and again in mid-October 1972. Concentrations of inorganic nitrogen, organic carbon, or phosphorus were high enough to indicate potential problems at about a quarter of the sampling sites. Temperature, dissolved oxygen, and pH values indicated a generally favorable capacity for recovery from degradation, although a number of streams east of the Allegheny and Monongahela Rivers are marginal or lacking. Regionally, sulfate is the dominant ion and was observed in concentrations of 40 milligrams per liter or more at 90 percent of the sites. Bicarbonate exceeded 100 milligrams per liter at 22 sites. A moderate to high degree of mineralization is indicated by conductance readings of more than 500 micromhos per centimeter at half of the sampling sites.
