Reconnaissance of the effect of landfill leachate on the water quality of Marshall Brook, Southwest Harbor, Hancock County, Maine
Bruce P. Hansen
1980, Open-File Report 80-1120
A small stream (2.2 square miles drainage area) receiving leachate from a landfill was studied from August through November 1979 to determine the impact of the leachate on water quality. The presence of un-ionized ammonia, considered toxic to some aquatic vertebrates, was indicated in samples taken from sections of the...
Hydrologic data for urban studies in the San Antonio, Texas, metropolitan area, 1977
Roberto Perez, Lynn Harmsen
1980, Open-File Report 80-743
Hydrologic investigations of urban drainage basins in Texas were begun by the U.S. Geological Survey in 1954. These studies are now in progress in Austin, Dallas, Dallas County, Fort Worth, Houston, and San Antonio.The Geological Survey, in cooperation with the Texas Department of Water Resources, expanded the existing gaging-station network...
Work plan for the Schuylkill River basin, Pennsylvania: Assessment of river quality as related to the distribution and transport of trace metals and organic substances
G.L. Pederson, Thomas H. Yorke, J. K. Stamer
1980, Open-File Report 80-566
The U.S. Geological Survey is making a river-quality assessment of the Schuylkill River basin in Pennsylvania from October 1978 to March 1981. It is part of a continuing program designed to demonstrate the effectiveness of river-quality studies for basin planning and water-resource management. Study objectives include determining (1) presence of...

Hydrologic assessment, Eastern Coal Province Area 23, Alabama
J.R. Harkins
1980, Open-File Report 80-683
The Eastern Coal Province is divided into 24 separate hydrologic reporting areas. The division is based on hydrologic factors, location, size, and mining activity. Hydrologic units (drainage basins) or parts of units are combined to form each area. Area 23 is located at the southern end of the Eastern Coal...
Low-flow characteristics of streams in the Menominee-Oconto-Peshtigo River basin, Wisconsin
B. K. Holmstrom
1980, Open-File Report 80-749
Low-flow characteristics of streams in the Menominee-Oconto-Peshtigo River basin, Wisconsin, are presented. Included are estimates of low-flow frequency at 12 gaging stations, flow duration at 10 gaging stations, and low-flow frequency characteristics at 23 low-flow partial-record stations and 137 miscellaneous sites. Equations are provided to estimate low-flow characteristics at ungaged...

Ground-water quality in North Idaho
D. J. Parliman, Harold R. Seitz, Michael L. Jones
1980, Open-File Report 80-596
From July 1977 to May 1978, water samples were collected from 116 wells north of the Palouse River in Idaho to define water-quality conditions, on a reconnaissance level, in major aquifers. Geologic and hydrologic data were combined with water-quality data to develop an understanding of factors affecting present and future...

Compilation of the data from the 1978 Hawaii seismic refraction experiment on the west flank of Mauna Loa
John J. Zucca, David P. Hill
1980, Open-File Report 80-451
In October 1978 (J.D. 286), the U.S. Geological Survey (USGS) established a seismic refraction line perpendicular to the Kona coast of Hawaii (Fig. 1). The purpose of the experiment was to define the crustal structure of the Kona coast and its relationship to the tectonics of Mauna Loa volcano. This...
