Geochemical, petrophysical, and drill hole database for Mesoproterozoic igneous rocks and iron ore deposits of the St. Francois Mountains, southeast Missouri Geochemical, petrophysical, and drill hole database for Mesoproterozoic igneous rocks and iron ore deposits of the St. Francois Mountains, southeast Missouri
Geochemical, petrophysical, and depth to the Paleozoic-Precambrian basement interface from drill hole data for Mesoproterozoic igneous rocks and iron ore deposits of the St. Francois Mountains, southeast Missouri (MMDB) are provided in this data release. The samples were collected as part of various agency programs and projects from 1967 through 2019. Most samples were collected by...
Datasets and R Scripts Used for the Water-Budget Analysis of the Medina and Diversion Lake System, Bandera, Bexar, and Medina Counties, Texas, 1955–2022 Datasets and R Scripts Used for the Water-Budget Analysis of the Medina and Diversion Lake System, Bandera, Bexar, and Medina Counties, Texas, 1955–2022
The U.S. Geological Survey—in cooperation with the San Antonio Water System and the Edwards Aquifer Authority—used data collected during four different periods (March 1955–August 1964, October 1995–September 1996, March 2001–June 2002, and March 2017–October 2022) as part of a new study to refine previously derived relations between the altitude of the water surface of Medina Lake and...

Groundwater quality at the Falcon Refinery Superfund Site near Ingleside, Texas, January 2024 Groundwater quality at the Falcon Refinery Superfund Site near Ingleside, Texas, January 2024
The Falcon Refinery Superfund Site (hereinafter referred to as “the Site”) is located in San Patricio County near Ingleside, Texas. The Site occupies approximately 104 noncontiguous acres that are divided into the North Site, the South Site, and a barge dock facility. Surface water drainage from the Site enters wetlands along the southeastern section of the property associated with this...
Passive water quality sampling at discrete vertical intervals to support the development of a conceptual site model development at the Geneva Industries/Fuhrmann Energy Superfund Site, Houston, Texas, 2023 Passive water quality sampling at discrete vertical intervals to support the development of a conceptual site model development at the Geneva Industries/Fuhrmann Energy Superfund Site, Houston, Texas, 2023
The Geneva Industries/Fuhrmann Energy Superfund Site (hereinafter referred to as "the Site") in southeastern Houston, Texas was historically used as a site for petroleum exploration and petrochemical production and is currently (2024) inactive. Previous remedies to clean up the contaminated site included the excavation and off-site disposal of polychlorinated biphenyl (PCB)-contaminated...
