Environmental Assessments of Barton Springs Pool and Barton Creek

Findings from toxicological assessments of sediment,soil, and water collected from Barton Springs Pool and Barton Creek in 2003.

Barton Springs Pool: Safe for Swimmers

In January 2003, the city of Austin asked the Texas Department of Health (TDH; now the Department of State Health Services) to conduct a health consultation on Barton Springs Pool due to concerns raised about possible contamination with polycyclic aromatic hydrocarbons (PAHs).

After evaluating analytical data collected by the city of Austin, the TCEQ, and the U.S. Geological Survey, TDH determined that Barton Springs Pool is safe for swimming and issued a formal report on this topic. In an April 17, 2003, letter to the city of Austin, the TCEQ concurred with TDH’s findings

What are PAHs? PAHs are a family of compounds that are formed during the incomplete combustion of wood, coal, gas, garbage, or other organic materials. Some PAHs are classified as probable human carcinogens, meaning prolonged exposure to sufficient levels of these compounds can increase the risk of developing cancer.

Studies by the TCEQ

Assessment of Contamination and Its Source

In response to concerns over contaminants found by the city of Austin in sediments that had been collected near Barton Creek, the TCEQ worked with the U.S. Environmental Protection Agency (EPA) to assess both the extent of contamination in the area and the source of the contaminants. Information from this study is available in PDF files (help with PDF):

Impacts of Contaminants on Aquatic Organisms

The initial data prompted the TCEQ, in conjunction with the EPA, to evaluate the potential toxicity of these sediments to aquatic organisms that live in and on the sediments. A study of the pool itself is complete. A study of Barton Creek is planned.
