Abstract: Dissolved-solids concentrations and loads can be estimated from streamflow records using a regression model derived from chemical analyses of monthly samples. The model takes seasonal effects into account by the inclusion of simple-harmonic time functions. Monthly mean dissolved-solids loads simulated for a 6-year period at U.S. Geological Survey water-quality stations in the Green River Basin of Wyoming agree closely with corresponding loads estimated from daily specific-conductance …

From introduction: This report relates to the first of the above objectives by describing stream quality in the Yampa River basin through 1976, with particular emphasis on conditions from August 1975 through September 1976. The content of this report is, at times, relatively technical. This is intentional. The report is aimed not at planners and decision makers but rather at those persons
assigned the task of having to design, implement, and interpret a river basin assessment. The techniques an…

From abstract: Planning waste-disposal facilities and impoundments is complicated by karst carbonate terrane in the Ozarks. Thermal imagery (8-13 micrometer wavelength) and color infrared photography aid in identifying losing streams, sinkholes and hydrologic conditions encouraging collapse. Imagery and photography were acquired in Greene and Reynold Counties, Mo., in March 1972 and June 1973. Differences in thermal levels correlating with losing and gaining reaches of Logan Creek valley, Reyno…

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.

Abstract: A flowing artesian well tapping the Floridan aquifer at Chekika Hammock State Park, Dade County, Florida, has been contaminating the overlying Biscayne aquifer with saline water since 1944. The contaminating plume extends approximately 7 miles
downstream and southeast of the well and ranges in width from 1 to 2 miles. The area of contamination is approximately 12 square miles. The primary contaminating chemical constituents are chloride, sodium, and sulfate ions.

Abstract: Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells. Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopmen…
