Extraction of metals from raw clinoptilolite-rich rocks exposed to water in heavy-metal-polluted drainages
Determinations of the quantity of solid material carried by the Colorado River are necessary for the proper consideration of plans for the development of the resources of the river. Much of the material carried by the river will be deposited in the proposed reservoirs and eventually will occupy a large part of the capacity of the reservoirs, so that their effectiveness for flood control or river regulation will be greatly decreased. A capacity of 6,000,000 acre-feet is reserved for silt storage in plans for a reservoir in Boulder Canyon that is to have a maximum capacity of about 25,000,000 to 30,000,000 acre-feet. It has been estimated that such a silt-storage capacity will not be entirely used for nearly 100 years.1...

Groundwater level measurements were made in 694 wells in Arkansas in the spring of 1988. These data are listed in tables by aquifer; then by county. For each well, the altitude of the land surface, the date measured, the depth to the water surface, and the altitude of the water surface are reported. Also reported are the net changes in water levels between 1987 and 1988 and between 1983 and 1988. This report also contains maps showing the average water level change, by county, between the years 1983 and 1988 for the aquifers in the Quaternary deposits and the Sparta and Memphis Sands. Hydrographs are included for selected wells completed in the Quaternary deposits and the Sparta and Memphis Sands. The aquifers in...

Relation of sediment and nutrient loads to watershed characteristics and land use in the Otisco Lake basin, Onondaga County, New York
Otisco Lake, the smallest and easternmost of New York State 's Finger Lakes, is the source of water supply for several villages in Onondaga County. In recent years, turbidity and algal blooms have periodically impaired the lake 's use for both water supply and recreation. Principal land uses within the Otisco Lake basin are woodland (39%) and cropland (49%). Conservation practices such as contour farming, strip cropping, and diversion ditches are applied to about 47% of the cropland in the basin. Runoff and concentrations of sediment and nutrients in the five major tributaries, which together drain about 70% of the lake 's watershed, were monitored from November 1981 through September 1983, and sediment and nutrient...
