1981, Open-File Report 81-650
This chapter contains practices used by the U.S. Geological Survey to assure the quality of analytical data for water, fluvial sediment, and aquatic organisms.These practices are directed primarily toward personnel making water-quality measurements. Some detail specific quality control techniques, others document quality assurance procedures being used by the Central Laboratories...
Probable high ground-water levels in Massachusetts
M. H. Frimpter
1981, Open-File Report 80-1205
Water-level records from an observation-well network are analyzed for utility in estimating probable high ground-water levels in three different geohydrologic environments in Massachusetts. Analyses were made of 83 observation wells with between 8 and 37 years of records. Maximum annual water levels occur most frequently in March and April. The...

1981, Circular 858-B
The names of 4,215 ore deposits shown on the Preliminary Metallogenic Map of North America are listed in alphabetical order by country, and by subdivisions of the larger countries (Canada, Mexico, and the United States). Map numbers, major and minor constituents, geographic coordinates, and a geologic code are given for...
Hydrologic effects of highway-deicing chemicals in Massachusetts
L.R. Frost Jr., S.J. Pollock, R.F. Wakelee
1981, Open-File Report 81-209
Methods of estimating annual mean and annual maximum chloride concentrations and sodium concentrations in streams were developed using multiple and simple linear regression techniques and data collected during the 1972-77 water years. Independent variables are easily obtainable parameters such as total salt application within a basin, annual precipitation, and drainage...

1981, Open-File Report 81-554
The U.S. Geological Survey (USGS), in cooperation with the U.S. Bureau of Land Management (BLM) and the Lamont-Doherty Geological Observatory (LDGO), collected 335 km of mid-range sidescan-sonar data in some of the tracts proposed for inclusion in Federal OCS (Outer Continental Shelf) Oil and Gas Lease Sale 56 and in...

1981, Open-File Report 81-210
Methods of estimating annual mean and annual maximum chloride concentrations in streams were developed through multiple and simple linear regression techniques using data collected during the 1972-77 water years. Independent variables are easily obtainable parameters, such as total salt application within a basin, annual precipitation, and drainage basin characteristics. Methods...

Quality of surface water at selected sites in the Suwannee River basin, Florida, April 1978 to December 1979
John E. Coffin
1981, Open-File Report 81-76
This report presents the results of analyses of water-quality samples collected from 13 surface-water sites in the Suwannee River basin in Florida from April 1978 to December 1979. The U.S. Geological Survey, in a cooperative investigative program with the Suwannee River Authority, has sampled a network of nine water-quality monitoring...

An observation-well network concept as applied to North Carolina
M. D. Winner Jr.
1981, Water-Resources Investigations Report 81-13
A statewide observation-well program is proposed for North Carolina based on four networks of observation wells with different but clearly-defined objectives. These are referred to as the (1) climatic-effects network, (2) terrane-effects network, (3) local-effects network, and (4) areal-effects network. The characteristics of each network are related to natural and...
Research in the Geysers-Clear Lake geothermal area, Northern California
Robert J. McLaughlin, Julie M. Donnelly-Nolan, editor(s)
1981, Professional Paper 1141
The Geysers-Clear Lake area is one of two places in the world where major vapor-dominated hydrothermal reservoirs are commercially exploited for electric power production. Because energy can be extracted more efficiently from steam than from hot water, vapor-dominated systems are preferable for electric power generation, although most geothermal electric power...

1981, Professional Paper 1205
The newly named Accotink Schist and Lake Barcroft Metasandstone of the Eastern Fairfax sequence are the structurally lowest metamorphic rocks in the northernmost Piedmont of Virginia. The Accotink consists of beds of pelitic schist that have thin basal intervals containing graded, very fine grained metasiltstone, as well as interbeds of...
