Marc F. Hult
1979, Open-File Report 79-1164
A network for monitoring the quality of water in the 13 principal aquifers in Minnesota has been designed and more than 400 wells and springs selected for sampling. The network organization includes four major elements; (1) point sampling, (2) point monitoring, (3) regional monitoring, and (4) site-specific monitoring. These elements...
A proposed U.S. resource classification system

Analysis of picric acid in water by high-performance liquid chromatography
D.F. Goerlitz
1979, Open-File Report 79-207
Methods for the determination of picric acid (2,4,6, trinitrophenol) in water employing high-performance liquid chromatography are presented. Ion-pair chromatography under an isocratic condition is performed on a reverse-phase column. Picric acid can be determined directly in water at a lower detection limit of 10 micrograms per liter. By use of...
Selected geologic information from drill holes in southeastern Iowa
Daniel J. Gockel
1979, Open-File Report 79-415
This report presents selected geologic information derived from wells in a 22-county area of southeastern Iowa. The information was extracted from the Automatic Data Processing (ADP) geologic file of the Iowa and U.S. Geological Surveys. The data presented include location, well identification number, and elevation of the well sites; depth and stratigraphic classification of...
Reconnaissance geology of the Wadi Shuqub Quadrangle, sheet 20/41 A, Kingdom of Saudi Arabia
Robert C. Greene, Louis Gonzalez
1979, Open-File Report 79-1353
The Wadi Shuqub quadrangle (sheet 20/41 A) lies in the high mountainous part of the Hijaz plateau in west-central Saudi Arabia. The quadrangle is underlain chiefly by Precambrian layered metasedimentary and metavolcanic rocks that are intruded by plutons ranging in composition from gabbroic to granitic. The metasedimentary rocks include quartzite,...
