Availability of Water from Limestone and Dolomite Aquifers in Southwest Ohio and the Relation of Water Quality to the Regional Flow System

Description: Abstracts: The largest ground-water supplies from the 150 to 450-foot thick carbonate-rock aquifer in southwest Ohio are available in a 2,800 square-mile area on the crest and eastern flank of the Cincinnati arch. Well production in the high-yield area is mainly from the Newburg zone, a permeable stratum in the lower part of the Bass Island group. A structure contour map on the top of the Lockport Dolomite shows that the Newburg zone conforms to the configuration of the Cincinnati arch. The chemical quality of the water in the consolidated-rock aquifers is intimately related to the regional flow system, and undergoes a progressive change from a calcium bicarbonate-type in recharge areas to a calcium sulfate-type in areas of natural discharge.

Map Showing Total Thickness of the Fox Hills-Lower Hell Creek Aquifer, Montana

Description: Introduction: In 1978 the U.S. Geological Survey began a 4-year study of aquifers in the northern Great Plains. The purpose of this map, which is a product of that study, is to show the total thickness of the Fox Hills-lower Hell Creek aquifer. Other maps show the altitude of the top (Feltism 1982a), cumulative thickness of sandstone (Feltis, 1982b), and potentiometric surface of water (Levings, 1982) in the Fox Hills-lower Hell Creek aquifer. These maps are part of a series that describes the geology and potentiometric surface of selected rock units of Jurassic or younger age in the plains area of Montana.

Ground Water in the Lajas Valley, Puerto Rico

Description: Abstract: Lajas Valley is plagued with problems of salinity and waterlogging the soils. Use of brackish (500 milligrams per liter) irrigation compounded ground water for the problem until an irrigation-drainage system was constructed in 1955. Lajas is an alluvium-filled limestone highlands. The alluvium, mostly clay and as much 300 feet (90 meters) thick, contains brackish ground water except in the recharge areas located along the foothills...Results from a digital model show that a network of discharge wells could alleviate waterlogging of the soils in the artesian area.

Appraisal of the Interconnection Between the St. Johns River and the Surficial Aquifer, East-Central Duval County, Florida

Description: From introduction: The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, conducted a 1-year study to determine the effects of proposed deepening of the navigation channel on the surficial aquifer. A specific objective was to determine the degree of interconnection that exists current between the limestone adjacent to the river and the limestone in the riverbed that is to be dredged.

Computer Simulation Model of the Pleistocene Valley-Fill Aquifer in Southwestern Essex and Southeastern Morris Counties, New Jersey

Description: From purpose and scope: The purpose of the present study by the U.S. Geological Survey in cooperation with the Division of Water Resources of the New Jersey of Environmental Protection is to make a quantitative hydrologic analysis of the known buried valley-fill aquifer in southwestern Essex and southeastern Morris County Counties in order to provide water-resources planners with the hydrologic bases to plan ground-water development and to allocate available water.

Reconnaissance of Ground-Water Quality, Eastern Snake River Basin, Idaho

Description: From purposes of approach of study: The purposes of this study were to: (1) Define, on a reconnaissance level, current (1979) water-quality conditions in major aquifers (water-yielding rock formations) in the eastern Snake River basin; (2) present available geologic and hydrologic data to assist in understanding the natural and man-caused factors that affect water-quality conditions; and (3) establish a hydrologic base upon which future comparisons can be made to evaluate changes.

Hydraulic Conductivity, Specific Yield, and Pumpage-High Plains Aquifer System, Nebraska

Description: From introduction: This is the second report by U.S. Geological Survey personnel in Nebraska that presents interpretive information for the High Plains aquifer system in the State...This report and the first report are complementary; information from both can be used to compute certain aquifer properties, knowledge of which is essential in the development of a management plan for the aquifer system.
