The Highland Lakes are a chain of five reservoirs (Lake Buchanan, Inks Lake, Lake Lyndon B. Johnson, Lake Marble Falls, and Lake Travis) on the Colorado River of central Texas that are collectively managed by the Lower Colorado River Authority (LCRA). Since 2013 the LCRA has used a combination of Soil and Water Assessment Tool (SWAT, version 2005 [Neitsch and others, 2005] or 2009...

The Wilcox Oil Company Superfund site (hereinafter referred to as “the site”) was formerly an oil refinery in northeast of Bristow in Creek County, Oklahoma. Historical refinery operations contaminated the soil, surface water, streambed sediments, alluvium, and groundwater with refined and stored products at the site. The Wilcox and Lorraine process areas are where the highest...

The Ouachita-Nevada Wood Treaters Superfund Site is a former wood-treatment facility located on approximately five acres of undeveloped land along the west side of North Main Street in Reader, Arkansas in Ouachita County. The former facility used wood treatment products containing pentachlorophenol (PCP) and heating oil, a chromium-copper-arsenate solution, and a mixture of diesel fuel...

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...

The Falcon Refinery Superfund site (hereinafter referred to as “the site”) is in an unincorporated area of San Patricio County, approximately one mile southeast of Ingleside, Texas. The site is an inactive petroleum refinery that operated during the 1980s and consisted of 32 aboveground storage tanks (ASTs) used to store petroleum products. Since 2004, many of these ASTs have been...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a Soil-Water-Balance (SWB) model of the Red River alluvial aquifer east of Lake Texoma in southeastern Oklahoma. Although the SWB model active area extends into parts of Texas and Arkansas, the SWB model was used to estimate recharge to the Red River alluvial aquifer between...

The North East 2nd Street Superfund site in Happy, Texas, overlies a groundwater plume of primarily carbon tetrachloride (CT) that is contained within an upper transmissive zone of the High Plains aquifer system (hereinafter referred to as the "Ogallala aquifer"). The Ogallala aquifer is contained in Tertiary-age sediments of the Ogallala Formation in the study area, which are described...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Salt Fork Arkansas River and Chikaskia River alluvial aquifers by using MODFLOW-2005 with the Newton formulation solver (MODFLOW-NWT). The model included the Chikaskia River alluvial aquifer, which is classified as a...

The land application of drill fluids is governed by rules established in the Oklahoma Administrative Rules (165:10-7) and permitted by the Oklahoma Corporation Commission (OCC). While data on the volume and location of land application is publicly accessible through the OCC's website, much of the information is in scanned form documents which limits the operability of these data. This...

The Edwards aquifer in south-central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water for use in agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB) and the Oka' Institute, constructed a Soil-Water-Balance (SWB) model of the eastern part of the Arbuckle-Simpson aquifer in south-central Oklahoma. The SWB model was used to estimate recharge to the eastern part of the Arbuckle-Simpson aquifer between January 2019 and December 2022 for...

This archive contains the data used to (1) summarize the hydrogeology and update the hydrogeologic framework of the Antlers aquifer in southeastern Oklahoma, and (2) develop a conceptual groundwater-flow model and water budget to estimate recharge to the Antlers aquifer during 1980–2022 as part of a hydrologic investigation (the model documentation report is available at https://doi.org...
