Surrogate regression models for computation of time series chloride concentrations, Chester County, Pennsylvania (2023) Surrogate regression models for computation of time series chloride concentrations, Chester County, Pennsylvania (2023)
In cooperation with state and county agencies, including the Chester County Water Resources Authority (CCWRA), the U.S. Geological Survey (USGS) has collected discrete stream samples for analysis of chloride concentrations at three real-time streamflow and water-quality monitoring (specific conductance) stations located in Chester County, Pennsylvania. Data were collected from 2010-2023...
Depth to Groundwater Measured from Wells Completed in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston Area, Texas, 2022 Depth to Groundwater Measured from Wells Completed in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston Area, Texas, 2022
This dataset documents depth to groundwater measurements made from wells screened in the Chicot aquifer, Evangeline aquifer, Jasper aquifer, Burkeville confining unit, Catahoula confining unit, or a combination of these hydrogeologic units in the greater Houston area, Texas for 2022. The U.S. Geological Survey (USGS) prepared this dataset in cooperation with the Harris‐Galveston...
Groundwater-Level Altitudes and Long-Term Groundwater-Level Changes in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston area, Texas, 2022 Groundwater-Level Altitudes and Long-Term Groundwater-Level Changes in the Chicot and Evangeline (Undifferentiated) and Jasper Aquifers, Greater Houston area, Texas, 2022
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...
Groundwater-level altitudes and volatile and semi-volatile organic compound concentrations at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund site, Liberty County, Texas, 2023 Groundwater-level altitudes and volatile and semi-volatile organic compound concentrations at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund site, Liberty County, Texas, 2023
In 2023, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level altitude and water-quality data from monitoring wells at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund Site in Liberty County, Texas. The data were collected to obtain information that could be used to provide an update on the status of groundwater
Volatile organic compounds in passive soil gas, indoor air, and groundwater samples at the Triangle Chemical Company Superfund Site, Orange County, Texas, 2021-2023 Volatile organic compounds in passive soil gas, indoor air, and groundwater samples at the Triangle Chemical Company Superfund Site, Orange County, Texas, 2021-2023
The Triangle Chemical Company Superfund site, in Orange County, Texas, was a chemical mixing and blending facility in the 1970s. According to the Environmental Protection Agency (EPA), poor waste management practices resulted in soil and groundwater contamination and fish-kills in Coon Bayou (U.S. Environmental Protection Agency, 2023). The Five-Year Review of the Triangle Superfund Site...
MODFLOW-NWT model used in simulation of groundwater availability in reaches 3 and 4 of the Washita River aquifer, southern Oklahoma, 1980–2017 MODFLOW-NWT model used in simulation of groundwater availability in reaches 3 and 4 of the Washita River aquifer, southern Oklahoma, 1980–2017
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 Washita River aquifer by using MODFLOW-2005 (Harbaugh, 2005) with the Newton formulation solver (MODFLOW-NWT). The 1973 Oklahoma Groundwater Law requires that the OWRB conduct hydrologic investigations of the State’s...
