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...
Voltages measured on long grounded electrically conducting lines in North American during several magnetic storms, 1891-1940 Voltages measured on long grounded electrically conducting lines in North American during several magnetic storms, 1891-1940
Presented is a list of voltages (electric potential differences) measured during magnetic storms on grounded long lines in the United States and Canada between 1891 and 1940. The sources for the list are published papers, technical documents, and newspapers. Each entry consists of the maximum voltage measured for each storm on a specified line connecting two ground points, nominally...
Voucher and metagenetic sequencing of DNA barcodes of wild-collected bees (Apoidea) from Iowa, USA Voucher and metagenetic sequencing of DNA barcodes of wild-collected bees (Apoidea) from Iowa, USA
High-throughput methods for identification of pollinator taxa are desirable to improve our understanding of pollinator distributions, population trends, and ecology. Genetic sequencing of taxonomically informative 'barcode' loci is one high-throughput strategy, which can be applied to individual specimens using Sanger technology and to complex mixtures using metabarcoding technology...
Wadeable stream habitat data integrated from multiple monitoring programs for the US from 2000-2022 Wadeable stream habitat data integrated from multiple monitoring programs for the US from 2000-2022
Wadeable stream habitat data from four long-term monitoring programs (AIM, AREMP, NRSA, PIBO MP) were obtained, pre-processed, transformed, and combined using R code following the Stream Habitat Metrics Integration (SHMI) Data Exchange Standard. The dataset includes 26 stream habitat metrics collected between 2000 and 2022 across the United States at ~12,000 locations from ~19,000 data...
WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey
A one-dimensional surface-water quality model of the central Salem River Basin, New Jersey was developed to examine the causes of eutrophication and predict the effects of reduced point and nonpoint source nutrient loads on water quality. The model was developed using the USEPA WASP code. The model simulates channel flow and the fate and transport of dissolved oxygen, oxygen demands...
Water Availability Tool for Environmental Resources for Haw Creek, Indiana Water Availability Tool for Environmental Resources for Haw Creek, Indiana
The Water Availability Tool for Environmental Resources (WATER-KY; Williamson and others, 2009) provides the ability to simulate streamflow for ungaged basins. This model integrates TOPMODEL (Beven and Kirkby, 1979) for pervious portions of the landscape with simulation of flow generated from impervious surfaces (USDA, 1986). A restructured version of this decision support tool...
Water chemistry and fish health effects for fathead minnow embryos exposed to sodium nitrate and matched conductivity controls for 21 days post fertilization Water chemistry and fish health effects for fathead minnow embryos exposed to sodium nitrate and matched conductivity controls for 21 days post fertilization
This data set describes developmental and physiological effects observed in fathead minnow embryos that were exposed to sodium nitrate or conductivity-matched controls. Exposures were conducted in the laboratory from fertilization through 21 days post-fertilization (dpf). Nitrate doses were 0, 2, 5, 10, 25, or 100 milligrams per liter nitrate-nitrogen; conductivity controls were matched...
Water chemistry and molecular eDNA data observed in experimental laboratory mesocosms exposed to different nitrogen amendments in the presence or absence of a nitrifier enriched microbial community Water chemistry and molecular eDNA data observed in experimental laboratory mesocosms exposed to different nitrogen amendments in the presence or absence of a nitrifier enriched microbial community
Data describe the results of a controlled laboratory mesocosm experiment evaluating the influence of a nitrifier enriched microbial community on silver carp (Hypophthalmichthys molitrix) milt eDNA degradation. Parameters described include the concentration results, limit of detection, and limit of quantification of two silver carp specific quantitative PCR assays and water chemistry...
Water chemistry data for samples collected at groundwater sites in the Montebello Oil Field study area, September 2014–October 2018, Los Angeles County, California Water chemistry data for samples collected at groundwater sites in the Montebello Oil Field study area, September 2014–October 2018, Los Angeles County, California
The California State Water Resources Control Board (State Water Board) initiated the Regional Groundwater Monitoring Program (RMP) to assess effects of oil and gas development on groundwater designated for any beneficial use. The U.S. Geological Survey (USGS) is the technical lead in conducting the RMP through the California Oil, Gas, and Groundwater (COGG) Program, working in...
