Abstract: Most public water supplies sampled in Florida meet the National Interim Primary and Proposed Secondary Drinking Water Regulations. This conclusion is based on a water quality reconnaissance of 131 raw and treated public supplies throughout the State during the period January through May 1979. In a few public supplies, primary drinking water regulation maximum contaminant levels were exceeded for mercury, turbidity, and gross alpha particle activity. Secondary drinking water regulations were also occasionally exceeded in some public supplies for such parameters as chloride, pH, color, dissolved solids, iron, and manganese. These parameters, however, are more related to the aesthetic quality of drinking water than to public health aspects.

Abstract: The Control Chart statistical methods, developed by Showhart for the control of quality of manufactured products, are applied to the control of Geiger-Miller counting instruments. Experiments are reported to show the use to the Control Chart method for detecting disturbances in instrumental behavior and for detecting radioactive effects so weak that they are near the limit of detection of the instruments. As a corollary, the control chart can be used to reduce to its practical limit the time required for tests.

Abstract: ^ digital computer model was used to model an unconfined sandstone aquifer (Arikaree aquifer) in about 340 square miles (880 square kilometers) in southeastern Wyoming. The model was calibrated by comparing observed and calculated changes in the potentiometric surface and leakage from the aquifer along streams during water year 1974. The comparison was fairly good for changes in the potentiometric surface and was good for leakage. The calibrated model was used to predict changes in the potentiometric surface and leakage through water year 1979, assuming no new ground-water development after 1974 and normal recharge to the aquifer. Water-level declines of as much as 14 feet (4.3 meters) were predicted, but much of the area would be relatively unaffected. The total predicted decrease in leakage between water years 1974 and 1979 was about 500 acre-feet (0.6 cubic hectometer) per year; the greatest decrease was predicted along streams closest to areas of pumpage.

From introduction: The primary objective of this study was to determine the net transport of zinc into the study area from urbanized perimeter, out of the study area across the northern boundary of the study area, and across the sediment-water interface within the study area, all within a limited time period. A secondary objective was to assemble as much data on other trace metals--their concentrations and chemical states in water, suspended solids, sediments and interstitial fluids--as possible within the time and funding constraints of the study in order to describe the existing trace metal conditions in the south bay. Thus the bulk of effort was directed toward evaluating the distribution and movements of zinc, but the data collected on the distribution and movements of zinc, but the data collected on the distribution of other metals is important and is reported here.

Abstract: At a 24,000-acre citrus grove, a connector well is proposed as a resource management tool for capturing water normally lost through evapotranspiration and by excess runoff. Such a well would connect the surficial sand aquifer with the deep, highly transmissive limestone Floridan Aquifer. Because of natural head differences, water would move by gravity flow from the sand into the Floridan Aquifer, thus replenishing water withdrawn for irrigation from the Floridan Aquifer. A 70-acre marsh was selected as the test site based on analyses of hydraulic conductivity, porosity, and water quality. Recharge rate through the connector well under steady-state conditions is estimated at 160 gallons per minute. The proposed connector well is designed to have 10-inch screens opposite zones in the 45-foot thick sand aquifer, be cased for 400 feet opposite confining beds and a secondary limestone aquifer, and be open hole for about 250 feet in the Floridan Aquifer. A graded-sand filter pack placed around the screened sections of the well will increase its efficiency.

Abstract: A digital water-quality model of the shallow alluvial aquifer near Barstow was evaluated to determine the applicability of the model computer program to varied hydrolic problems. The evaluation was made on the basis of the data requirements of the model, the characteristics and limitations of the model computer program, the relevance of the model results, and the computer costs associated with the model. Two-well tracer-dilution tests may not be a workable means of determining the aquifer dispersivity and porosity for use in a water-quality model with a large grid interval is under consideration because of the relative insensitivity of such a model to dispersivity. The model results were relevant to the real-life head and water-quality conditions in the aquifer near Barstow and provided an excellent means of evaluating the cause and effect relations associated with ground-water pollution.
