    dct:description "In 2020, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level altitude data and water-quality samples from monitoring wells at the Petro-Chemical Systems, Inc. (Turtle Bay) Superfund Site in Liberty County, Texas to evaluate the status of groundwater contamination at this previously remediated site. The dataset includes groundwater-level altitudes and field properties measured at 11 monitoring wells along with data from environmental and quality assurance/quality control water quality samples collected at each well. Water-quality samples were analyzed for a suite of volatile and semivolatile organic compounds." ;
