Aquifers in the Sokoto basin, northwestern Nigeria, with a description of the general hydrogeology of the region
H. R. Anderson, William Ogilbee
1973, Water Supply Paper 1757-L
The Sokoto Basin of northwestern Nigeria lies in the sub-Saharan Sudan belt of west Africa in a zone of savannah-type vegetation. Rainfall, averaging about 30 inches annually in much of the basin, occurs chiefly in a wet season which lasts from May to October. A prolonged dry season extending from...
Mercury in the Carson and Truckee River basins of Nevada
A. S. Van Denburgh
1973, Open-File Report 73-352
Upstream from major pre-1900 ore milling in the Carson and Truckee River basins, "background" concentrations of total mercury in the upper 1 to 3 inches of sand- to clay-sized stream-bottom sediment are less than 0.1 ug/g (microgram per gram). Downstream, measured concentrations were as much as 200 times the background...

Review of wastewater problems and wastewater-management planning in the San Francisco Bay region, California
Walter G. Hines
1973, Open-File Report 73-112
The San Francisco Bay region has suffered adverse environmental effects related to the discharge of municipal-, industrial-, and agricultural- wastewater and storm-water runoff. Specific pollutional properties of theses discharges are not well understood in all cases although the toxic materials and aquatic-plant nutrients (biostimulants) found in municipal and industrial...

Liquefaction potential of unconsolidated sediments in the southern San Francisco Bay Region, California
T. Leslie Youd, D.R. Nichols, E. J. Helley, K. R. Lajoie
1973, Open-File Report 73-368
A preliminary map of liquefaction potential of unconsolidated sediments has been made for the southern part of the San Francisco Bay region. Map zones are established on the basis of recent detailed geologic mapping. Liquefaction potential for each zone is estimated from an analysis of lithologic, water-table and standard penetration test data. Due to empirical...
