Ground-Water-Quality Assessment of the Central Oklahoma Aquifer, Oklahoma:Analysis of Available Water-Quality Data through 1987. National Water-Quality Assessment. (Chapter B)

摘要

The purpose of the paper is to report on the assessment of the water quality ofthe Central Oklahoma aquifer using the information available through 1987. The scope of the work included compiling data from Federal, State, and local agencies; evaluating the suitability of the information for conducting a regional water-quality assessment; mapping regional variations in major-ion chemistry; calculating summary statistics of the available water-quality data; producing maps to show the location and number of samples that exceeded water-quality standards; and performing contingency-table analyses to determine the relation of geologic unit and depth to the occurrence of chemical constituents that exceed water-quality standards. The paper provides an initial description of water-quality conditions in the Central Oklahoma aquifer study unit.
