Annotated bibliography on artificial recharge of ground water, 1955-67
Donald C. Signor, Douglas J. Growitz, William Kam
1970, Water Supply Paper 1990
Artificial ground-water recharge has become more important as water use by agriculture, industry, and municipalities increases. Water management agencies are increasingly interested in potential use of recharge for pollution abatement, waste-water disposal, and re-use and reclamation of locally available supplies. Research projects and theoretical analyses of operational recharge systems show...
Water as an urban resource and nuisance
H. E. Thomas, William Joseph Schneider
1970, Circular 601-D
Generally, when people speak of water as a resource, they are considering its good aspects and recognizing that it is essential for life and living. Sometimes or at some places or to some people, the same water may be annoying or unpleasant and thus a nuisance-for example, rain at a...
Remote detection of geochemical soil anomalies
Frank Cogswell Canney
1970, Open-File Report 70-54
This paper describes a preliminary experiment that was made to compare the spectral reflectance from trees growing in soil over a mineral deposit with reflectance from trees of the same species growing in a nearby unmineralized area. Although the measurements were made on a relatively small number of trees, some...

1970, Water Supply Paper 1899-K
This glossary includes most terms used in describing karst geomorphologic features and processes. The terms are primarily those used in the literature of English-speaking countries, but a few of the more common terms in French, German, and Spanish are included, with references to the corresponding English terms where they are...
Age of the Bedford Shale, Berea Sandstone, and Sunbury Shale in the Appalachian and Michigan basins, Pennsylvania, Ohio, and Michigan
Wallace De Witt Jr.
1970, Bulletin 1294-G
The suggestion by Sanford (1967, p. 994) that the Bedford Shale, Berea Sandstone, and Sunbury Shale of the Michigan basin are of Late Devonian age because these strata contain Hymenozonotriletes lepidophytus Kedo is invalid for these formations in the Appalachian basin, the area of their type localities. Endosporites lacunosus Winslow,...
