Hydrologic activities of the U.S. Geological Survey in support of the Radionuclide Migration Program, Nevada Test Site and vicinity, Nye County, Nevada, fiscal year 1987

Hydrologic activities during the 1987 fiscal year by the U.S. Geological Survey in support of the Radionuclide Migration Program at the Nevada Test Site are summarized. These activities included monitoring groundwater levels; compiling and entering geohydrologic data into the U.S. Geological Survey computerized groundwater database; providing technical support to the Radionuclide Migration Committee and the Containment Evaluation Panel; and the planning, drilling, and sampling of the UE20n-1 hole. Groundwater levels were monitored continuously at 2 wells and intermittently at 36 selected wells, test holes, and emplacement holes. Selected monthly water-level measurements are listed for the continuously monitored wells and intermittent measurements are listed for the selected wells, test holes, and emplacement holes. Progress continued on four groundwater hydrology reports of the Nevada Test Site area. (Thacker-USGS, WRD)

Hydraulic conductivity and water quality of the shallow aquifer, Palm Beach County, Florida

Subsurface geophysical logs were correlated with logs of drill cuttings to determine the permeability of selected zones of the shallow aquifer, Palm Beach County, Fla. The hydraulic conductivity of the aquifer is estimated to range from 1 to 130 feet per day, based on lithology and physical properties. The yield of wells penetrating this aquifer ranges from 100 to more than 1,000 gallons per minute. Water samples were collected from different depths throughout the county and analyzed for chemical constituents. Stiff diagrams illustrate the changes in types of water by depth and area. Water of suitable quality is in the eastern parts of the county. In this area the aquifer is the thickest and most permeable. The concentration of chemical constituents in the water increase in a westerly direction. The water in the western parts of the county is unsuitable for most purposes. (Woodard-USGS)

The occurrence of the longjaw cisco, Leucichthys alpenae , in Lake Erie

The longjaw cisco, Leucichthys alpenae , is shown to be a species new to the Lake Erie fauna. The taxonomic work on Lake Erie ciscoes is reviewed. Thirty three specimens of L . alpenae taken in 1946, 1947 and 1957 are compared morphometrically with Leucichthys artedi of Lake Erie, the only other cisco species in the lake. L . alpenae has a longer and deeper head, longer maxillary and fewer gill rakers. L . alpenae is more distinct from L . artedi in Lake Huron than in Lake Erie. The rate of growth of L . alpenae in Lake Erie compares favourably with that in Lake Michigan.
