The following report is the first volume documenting the radiometric and magnetic data taken during the month of October, 1979, by EG&G geoMetrics primarily in the state of Texas in the quadrangles: Tyler, Texarkana, and Waco. This volume contains the survey description, specifications, data processing methods, interpretation methods, interpretation methods, and regional geologic review.

This report is one part of the second volume containing data on quadrangles of Texas, Oklahoma, Arkansas and Louisiana. This volume contains the detailed geologic summary, interpretation report, standard deviation maps, pseudo-contour maps, interpretation map, flight line and geologic base map, individual corrected profiles, computer map unit histograms and statistical tables for the Texarkana quadrangle.

From abstract: A study was made of the White River between Lake Sequoyah and Beaver Lake to determine the quality of the river under existing conditions and how the effluent from the Fayetteville municipal wastewater-treatment plant, the only point source discharger of waste effluent to the river, affects this quality.

From introduction: The primary purpose of this study was to identify perennial streams. The secondary purpose was to classify them by flow. This information can be useful for planning and designing water supplies, analyzing environmental and economic impacts of various projects, water-quality modeling, and the determination of optimum and maintenance flows for a variety of instream uses.

This report provides radiometric and magnetic data for the Harrison quadrangle of southern Missouri and northern Arkansas that was acquired and processed in May of 1980. Appendix A provides a detailed summary of data acquisition, processing, interpretation, and presentation methods; Appendix B contains a flight summary report for the quadrangle.

The following report analyzes the aerial gamma ray and magnetic data taken from the El Dorado quadrangle in southern Arkansas that was compiled in 1980. This report contains a detailed geologic summary, interpretation report, reduced scale copies of all maps and profiles, histograms, and statistical tables for the quadrangle.

This report presents data on ground water in the Springfield-Salem plateaus in Southern Missouri and Northern Arkansas. It contains maps, graphs, and tables.

From introduction: The purpose of this report is (1) to present the results of time-of-travel and dispersion measurements made on selected streams in Arkansas from 1971 to 1981, and (2) to present a graphical method for quickly predicting traveltime, peak concentration, and duration of an accidentally spilled contaminant for those streams where enough data are available.

"The objective [of this report] is to produce an inventory of those important ecological along the lower Mississippi River on which siting of major industrial facilities and land clearing operations could have an impact."
