This paper presents the recent changes in the Texas water quality standards for contact recreation. It is based on the results of a statewide Bacterial Indicator Study performed for the Texas Natural Resource Conservation Commission. First, the history of the standards is reviewed.
Then the situation that developed as a result of the 303(d) listing process is described, along with the study recommendations for changes to the standards. The main recommendations were adopting the criteria and levels recommended by US Environmental Protection Agency in 1986, along with
changes in the monitoring protocols. Additional recommendations for dealing with the highly variable conditions in small streams, that were never considered when the US Environmental Protection Agency recommended criteria were developed, are also presented in the study and paper
