The U.S. Geological Survey (USGS), in cooperation with the Harris-Galveston Subsidence District and Fort Bend Subsidence District, constructed a finite-difference numerical groundwater-flow model of the northern Gulf Coast aquifer region for 1897 through 2018 using MODFLOW 6 with the Newton formulation solver to simulate groundwater flow and land-surface subsidence. Model parameter estimation and uncertainty analysis were conducted with PEST++ Iterative Ensemble Smoother software. The simulated results are described in the associated U.S. Geological Survey Professional Paper 1877. The model archive provided in this U.S. Geological Survey data release includes all the necessary files to run the MODFLOW 6 model and...

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, Lone Star Groundwater Conservation District, and Brazoria County Groundwater Conservation District produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot and Evangeline aquifers (undifferentiated) and Jasper aquifers in the greater Houston area, Texas. This dataset shows current‐year (2021) groundwater‐level altitudes for each aquifer, 1–year (2020–21), 5‐year (2016–21) groundwater‐level changes for each aquifer, long‐term (1990–2021 and 1977–2021) groundwater‐level changes for the Chicot and Evangeline aquifers (undifferentiated)...

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 (EA Engineering, Science, and Technology, Inc., 2019) of the Ogallala aquifer. The Ogallala aquifer is contained at the site in Tertiary-age sediments of the Ogallala Formation, which are described by Nordstrom and Fallin (1989, p.10) as "tan, yellow, and reddish-brown, silty to coarse-grained sand mixed or alternating with yellow to red silty clay and variable sized gravel." The plume originated from the application of fire-retardant chemicals to the ground surface during the extinguishing of a fire at a grain storage elevator in 1962....

Between 2012 and 2015, water-quality samples were collected by the USGS in cooperation with the Clearwater Underground Water Conservation District (CUWCD), the Bell County Adaptive Management Coalition (BCAMC), and other entities, with a primary goal of characterizing the groundwater resources in Bell County, Texas. Water resources associated with the northern segment of the Edwards aquifer near the Village of Salado were of primary interest, but water resources in the Trinity aquifer were also investigated to a lesser degree (the assessment focused on a springs complex in the Village of Salado). Data associated with other water quality samples collected by the USGS in Bell County during 1978 to 2017, outside of...
