Abstract

To determine whether motorized watercraft are a major factor in MTBE surface water contamination through recreation, surface water samples were collected in a multipurpose reservoir (Lake Austin) during periods of high and low recreational watercraft use. A non-parametric, one-tailed, Mann-Whitney U two-sample analysis was used to determine if there was a significant difference between the summer and winter sampling. Concentrations of MTBE above the Texas taste and odor criteria of 15 ppb were not found in Lake Austin. Although a significant difference was found between the summer and winter concentrations (1.48 ppb) of MTBE (p<0001), MTBE contamination due to motorized recreational boating did not pose a health threat in Texas.
