Abstract

Descriptive statistics were calculated for selected water quality data for 116 water quality stations on Arkansas rivers and streams. Water quality properties summarized included pH, specific conductance, dissolved oxygen, total alkalinity, total hardness, common dissolved constituents, phosphorus, nitrogen, biochemical oxygen demand, bacteria, turbidity, suspended sediment, and several trace metals. Regression equations and related statistics describing the relation between specific conductance and total alkalinity and several dissolved constituents also were calculated. Typical water quality (based upon median values at individual stations) of physiographic sections and major rivers of Arkansas also is discussed. Discernible differences in water quality exist between sections and major rivers. The regression analysis indicated that the usefulness of specific conductance as a predictor of other water quality values is variable. The relation between specific conductance and the other property is not statistically significant (p>0.05) about 30% of the time. (USGS)
