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

From introduction: This report contains the findings of the first full year of data collected as part of a 3-year study to measure sediment discharges in the East Branch Mahoning Creek during installation of erosion and sedimentation controls by the surface miners.

From introduction: This report describes rainfall-runoff modeling for three subbasins of the West Branch Brandywine Creek basin. Effects of increased runoff from continued urbanization of the basin and of proposed flood-control structures for both the present and projected population are evaluated for the West Branch Brandwyne Creek at Coatesville and Modena and for Sucker Run at State Route 82.

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.

"This appendix contains phase arrival information for local and near-regional events which have been well recorded by the Anna Seismic Network." (p. B1)

From introduction: "Following the USSR announcement of its intention to resume testing, arrangements were made for the three stations collecting individual rainfall samples to begin analyses for short-lived nuclides. Some of the data are now available and are reported here." From Data: "The available data, including samples for Houston, Texas and Louisville, Kentucky are given in the tables at the end of this report."
