A facility designed to monitor the unsaturated zone during infiltration of tertiary-treated sewage, Long Island, New York
Robert C. Prill, Edward T. Oaksford, James E. Potorti
1979, Water-Resources Investigations Report 79-48
A facility consisting of a circular recharge basin 6.10 meters in diameter with a central observation manhole was developed on Long Island, N.Y., to study the role of the unsaturated zone during aquifer recharge with tertiary-treated sewage. The manhole extends through most of the 7.5-meter-thick unsaturated zone, which is composed...
Backwater at bridges and densely wooded flood plains, Yockanookany River near Thomastown, Mississippi
B.E. Colson, C. O. Ming, George J. Arcement
1979, Hydrologic Atlas 599
Floodflow data that will provide a base for evaluating digital models relating to open-channel flow were obtained at 22 sites on streams in Alabama, Louisiana, and Mississippi. Thirty-five floods were measured. Analysis of the data indicated methods currently in use would be inaccurate where densely vegetated flood plains are crossed...
The corrosive well waters of Egypt's western desert
Frank Eldridge Clarke
1979, Water Supply Paper 1757-O
The discovery that ground waters of Egypt's Western Desert are highly corrosive is lost in antiquity. Inhabitants of the oases have been aware of the troublesome property for many decades and early investigators mention it in their reports concerning the area. Introduction of modern well-drilling techniques and replacements of native...
Arsenic, nitrate, iron, and hardness in ground water, Fairbanks area, Alaska
Paula R. Johnson, D.E. Wilcox, W.D. Morgan, Josephine Merto, Ruth McFadden
1979, Open-File Report 78-1034
Well water with concentrations of arsenic and nitrate exceeding U.S. Environmental Protection Agency standards occurs sporadically throughout the hills north of Fairbanks, Alaska. The arsenic contamination has not been correlated with placer or other mining activity. The high levels of nitrate do not generally appear related to septic waste contamination....
Water resources data of the Seward area, Alaska
Larry L. Dearborn, Gary S. Anderson, Chester Zenone
1979, Water-Resources Investigations Report 79-11
Favorable geohydrologic conditions in the Seward area provide several choices for developing additional water supplies. Abundant stream runoff and the prospects for expanded well-field development in the Jap Creek alluvial fan, as well as other similar fans, allow a selection of future water sources based on factors other than the...
Results of testing landspreading of treated municipal wastewater at St. Petersburg, Florida
R.C. Reichenbaugh, David P. Brown, Carole L. Goetz
1979, Water-Resources Investigations Report 78-110
Chlorinated secondary-treated effluent was used to irrigate a grassed 4-acre site at rates of 2 and 4 inches per week for periods of 11 and 14 weeks, respectively. Part of the site was drained by tile lines 5 feet below land surface. Irrigation of the drained plot resulted in rapid...
Abundance and distribution of thorium in the carbonatite stock at Iron Hill, Powderhorn District, Gunnison County, Colorado
Theodore J. Armbrustmacher
1979, Open-File Report 79-536
The carbonatite stock at Iron Hill is part of an alkalic complex of Cambrian or latest Precambrian age containing pyroxenite, uncompahgrite, ijolite, nepheline syenite, and related rocks characterized by their subsilicic composition and by their lack of calcic plagioclase. Thorium averages 36.2 parts per million (ppm) Th (0.0041 percent Th02)...
Progress report on water resources of the Tulalip Indian Reservation, Washington
B. W. Drost
1979, Water-Resources Investigations Report 78-31
Updated information on the Tulalip Indian Reservation 's resources indicates that the newly developed tribal well field yielded about 100 million gallons of water during August 1975-October 1976. At 16 or 17 streamflow sites, mean annual discharges during the 1976 water year exceeded those of the 1975 water year by...
