Abstract

Water quality is degrading over time at Main Barton Springs, Austin, Texas, as determined by multiple linear regression analyses (COA 2005). Similar techniques are applied to long-term monitoring data from 5 other Barton-related springs: Upper Barton Springs, Old Mill Springs, Eliza Springs, Backdoor Springs and Cold Springs. Categorical variables representing low-flow condition, laboratory method, filter fraction and analytical method were also used in the regression analysis. Varying temporal trends were observed at study springs. Due to variations in contributing watersheds, local influences, and aquifer mixing, observed temporal trends at other Barton complex springs did not always match observed trends at Main Barton Springs noted in previous analyses.
