    • Groundwater-level altitudes and volatile and semivolatile organic compound concentrations at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund site, Liberty County, Texas, 2024

    Metadata Updated: September 12, 2025

    The U.S. Geological Survey (USGS), in cooperation with the U.S. Environmental Protection Agency (EPA), collected groundwater-level altitude and water-quality data from selected monitoring wells at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund site in Liberty County, Texas on April 29 and November 13, 2024. These data were collected to obtain information that could be used to provide an update on the status of groundwater contamination at the site. This data release documents the groundwater-level altitudes, field properties, and water-quality data obtained in April and November 2024 from six of the 11 on-site monitoring wells where similar data were collected by the USGS during sampling that took place in August and September 2020 (Braun and Becher 2022; Lucena, 2022). The same six wells that were sampled in April and November 2024 were also sampled in April 2023 (Adams, 2023). Each water-quality sample was analyzed for a suite of volatile and semivolatile organic compounds.
