The effects of water quality on brine discharged from oil and gas recovery operations are described for surface water and ground water in two small watersheds in eastern Kentucky. The brine, which had salinity that was often several times that of sea water, led to significantly higher concentrations of several minerals in surface water, particularly in the first and second order streams. Concentractions as high as 50,000 mg/I for sodium and 64,000 mg/I for chloride were measured in streams. The. differences in chemical concentrations for various chemicals over the period of the study were ascribed to temporal variability, particularly due to differences between wet and dry seasons, and to spatial variability, particularly due to dilution and other chemical decay processes. Chemical decay coefficients for sodium and chloride were developed as a function of watershed area for possible application to similar watersheds. There was some evidence that the brine was influencing the Licking River, the major stream that drains the eastern part of Kentucky.
