Movement of a solute in the Potomac River estuary at Washington, D.C., at low inflow conditions
James F. Wilson, Ernest D. Cobb, Nobuhiro Yotsukura
1969, Circular 529-B
The movement of a solute, as represented by a soluble fluorescent dye, was observed in the Potomac River estuary at Washington, D.C. The average net rate of downstream movement of the solute centroid was less than 0.6 mile per day. The movement of a solute is highly dependent on the...
Quantitative comparison of some aesthetic factors among rivers
Luna Bergere Leopold
1969, Circular 620
It is difficult to evaluate the factors contributing to aesthetic or nonmonetary aspects of a landscape. In contrast, aspects which lend themselves to cost-benefit comparisons are now treated in a routine way. As a result, nonmonetary values are described either in emotion-loaded words or else are mentioned and thence forgotten.The...
Mercury in soil gas and air--A potential tool in mineral exploration
Joseph Howard McCarthy, W.W. Vaughn, R. E. Learned, J. L. Meuschke
1969, Circular 609
The mercury content in soil gas and in the atmosphere was measured in several mining districts to test the possibility that the mercury content in the atmosphere is higher over ore deposits than over barren ground. At Cortez, Nev., the distribution of anorhalous amounts of mercury in the air collected...

Water for the cities - The outlook
William Joseph Schneider, Andrew Maute Spieker
1969, Circular 601-A
Except perhaps for the arid Southwest, water resources are generally sufficient to meet the needs of cities for the foreseeable future. Cities will continue to expand and additional rural areas will be converted to urban and suburban complexes. Demands for urban water will continue to rise and this will place...
Asbestos occurrence in the Eagle C-4 quadrangle, Alaska
Helen Laura Foster
1969, Circular 611
An asbestos occurrence was discovered in a remote part of the Eagle quadrangle, Alaska, in the summer of 1968 during geologic reconnaissance in connection with the U.S. Geological Survey's Heavy Metals program. The exposed part of the deposit consists of large joint blocks of serpentine which are cut by closely...
Disposal of liquid wastes by injection underground--Neither myth nor millennium
Arthur M. Piper
1969, Circular 631
Injecting liquid wastes deep underground is an attractive but not necessarily practical means for disposing of them. For decades, impressive volumes of unwanted oil-field brine have been injected, currently about 10,000 acre-feet yearly. Recently, liquid industrial wastes are being injected in ever-increasing quantity. Dimensions of industrial injection wells range widely...
