Groundwater-Level Altitudes and Volatile and Semivolatile Organic Compound Concentrations at the Petro-Chemical Systems, Inc. (Turtle Bayou) Superfund Site, Liberty County, Texas, 2020
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 Bayou) 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.
The EnviroMapper tool combines interactive maps and aerial photography to display facility-based information from the Envirofacts Warehouse. There are now six geographically based selection options to help you zoom into areas of interest. Each option essentially does the same thing, offering maps and aerial photos that can be used to locate EPA regulated facilities. However, two options, "By Address" and "By Facility" have the potential to zoom to a point closer to or exactly on your facility.
The Anacostia Watershed lies within the Chesapeake Bay drainage basin, and is one of the most urban watersheds within the basin. According to the Fish and Wildlife Service, the watershed spans over 175 square miles between Maryland and the District of Columbia and is considered by many to be one of the most degraded waterways in the United States. Watts Branch is a tributary stream of the Anacostia River, and flows into the Potomac River which eventually empties into the Chesapeake Bay. In 2010, several partnerships were formed to restore a section of the Watts Branch stream and riparian area. The restoration efforts were focused on a highly polluted 1.8 mile stretch of the stream, running from the border of Prince...
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 indicated groundwater in the upper water-bearing zone might be migrating off-site toward the southwest (U.S. Environmental Protection Agency, 2016). There are concerns regarding potential risks to human health from contaminated soil vapor in existing or future structures in the area. To evaluate the status of volatile organic compound...
Emissions & Generation Resource Integrated Database - Plants for the Great Plains Landscape Conservation Cooperative
The Great Plains Landscape Conservation Cooperative (GPLCC, http://www.greatplainslcc.org/) is a partnership that provides applied science and decision support tools to assist natural resource managers conserve plants, fish and wildlife in the mid- and short-grass prairie of the southern Great Plains. It is part of a national network of public-private partnerships — known as Landscape Conservation Cooperatives (LCCs, http://www.fws.gov/science/shc/lcc.html) — that work collaboratively across jurisdictions and political boundaries to leverage resources and share science capacity. The Great Plains LCC identifies science priorities for the region and helps foster science that addresses these priorities to support wildlife...
Groundwater-Level Elevations and Concentrations of Selected Water-Quality Properties at the Many Diversified Interests, Inc. Superfund Site, Houston, Texas, September 2022
In September 2022, the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, collected groundwater-level elevation data and water-quality samples from monitoring wells at the Many Diversified Interests, Inc. Superfund Site in Houston, Texas to evaluate the status of groundwater contamination at this previously remediated site. The dataset includes groundwater-level elevations and field properties measured at 12 monitoring wells along with data from environmental and quality assurance and quality control water-quality samples collected at each well. Water-quality samples were analyzed for arsenic, manganese, molybdenum, benzo(a)pyrene, and petroleum hydrocarbons.
Continuous groundwater-level monitoring to support the development of a conceptual site model development at the Geneva Industries/Fuhrmann Energy Superfund Site, Houston, Texas, 2022–23
The Geneva Industries/Fuhrmann Energy Superfund Site in southeastern Houston, Texas was historically used as a site for petroleum exploration and petrochemical production and is currently (2023) inactive. Previous remedies to clean up the contaminated site included: excavation and off-site disposal of polychlorinated biphenyl-contaminated soils, capping of residual water on-site with a perimeter slurry wall, the recovery and treatment of trichloroethylene-contaminated groundwater, and institutional controls (Environmental Protection Agency, 2019). A conceptual site model (CSM) does not yet exist and is needed to (1) understand how site conditions have changed since earlier investigations; (2) reevaluate site contaminants...
This map service contains GIS data in Web Mercator from the EPA Office of Water for the National Hydrography Dataset (NHD) integrated with reach-related information from the USEPA Reach File Version 3.0-Alpha release (RF3-Alpha). This service also includes hydrographic landmark features in NHD. It is available as a WMS, KML, and REST service as well as the native MapServer service.
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 contamination at the site. This data release documents the groundwater-level altitudes, field properties, and water-quality data obtained in 2023 from six of the 11 monitoring wells where similar data were collected by the U.S. Geological Survey in August and September 2020 (Braun and Becher 2022). The environmental and quality-control...
