Proximity of Private Domestic Wells to Underground Storage Tanks in Oklahoma (PUBLISHED REPORT)
For protecting drinking water supplies, the locations of areas with reliance on private domestic wells (hereafter referred to as “wells”) and their relationship to contaminant sources need to be determined. A key resource in the U.S. was the 1990 Census where the sour...
Locations with High Reliance on Private Wells: Not Always Where You Think They Are (PRESENTATION)
For developing contaminant management strategies and protecting drinking water supplies, the locations of areas with reliance on private domestic wells (PDWs) and their relationship to contaminant sources need to be determined. From 1960 to 1990, a key resource in determining are...

An Ultra-Sensitive Method for the Analysis of Perfluorinated Alkyl Acids in Drinking Water using a Column Switching High-Performance Liquid Chromatography Tandem Mass Spectrometry (JOURNAL)
In epidemiological research, it has become increasingly important to assess subjects' exposure to different classes of chemicals in multiple environmental media. It is a common practice to aliquot limited volumes of samples into smaller quantities for specific trace level chemi...
Where in the Marsh is the Water (and When)?: Measuring and modeling salt marsh hydrology for ecological and biogeochemical applications (PRESENTATION)
Salt marsh hydrology presents many difficulties from a measurement and modeling standpoint: the bi-directional flows of tidal waters, variable water densities due to mixing of fresh and salt water, significant influences from vegetation, and complex stream morphologies. Because o...
Role of solution chemistry in the retention and release of graphene oxide nanomaterials in uncoated and iron oxide-coated sand (JOURNAL)
Upon increasing production and use of graphene oxide nanoparticles (GONPs), concerns agitate over their potential impacts and risks to the environment, ecosystem, and human health. An improved understanding of the fate and transport including remobilization of GONPs in the subsur...
Use of Nanoscale Emulsified Zero-valent Iron to Treat a Chlorinated Solvent Source Zone at Site 45, Marine Corp Recruit Depot, Parris Island, South Carolina (COMMUNICATION PRODUCT)
This document summarizes the research activities currently underway at the Solid Waste Management Unit 45 (Site 45), Marine Corps Recruit Depot, Parris Island, South Carolina. A pilot field test was initiated in 2005 at this site to evaluate the effectiveness of nanoscale emulsif...
Evidence of sulfate-dependent anaerobic methane oxidation within an area impacted by coalbed methane-related gas migration (JOURNAL)
The rapid development of unconventional gas resources has been accompanied by an increase in public awareness regarding the potential effects of drilling operations on drinking water sources. Incidents have been reported involving blowouts (e.g., Converse County, WY; Lawrence Tow...
Environmental implications and applications of engineered nanoscale magnetite and its hybrid nanocomposites: A review of recent literature (JOURNAL)
This review focus on environmental implications and applications of engineered magnetite (Fe3O4) nanoparticles (MNPs) as a single phase or a component of a hybrid nanocomposite that take advantages of their superparamagnetism and high surface area. MNPs are synthesized via co-pre...
Petroleum Release Assessment and Impacts of Weather Extremes (PRESENTATION)
Contaminated ground water and vapor intrusion are two major exposure pathways of concern at petroleum release sites. EPA has recently developed a model for petroleum vapor intrusion, called PVIScreen, which incorporates variability and uncertainty in input parameters. This ap...
Green Infrastructure Fact Sheet (COMMUNICATION PRODUCT)
We briefly describe the environmental issues associated with stormwater runoff, describe the purpose of green infrastructure and key techniques used. We also highlight environmental and economic benefits of green infrastructure through text and tables, as well as provide US wate...
Hyporheic Cooling with Implications for Support of Fish Habitat in the Willamette Valley, Oregon (PRESENTATION)
It has been hypothesized that groundwater flow which originates from a river and then returns to it could result in a temperature buffering benefit, resulting from dissipation of heat during porous media flow. We installed 50 monitoring wells in a geomorphologically active area a...
Southwestern Intermittent and Ephemeral Stream Connectivity (JOURNAL)
Ephemeral and intermittent streams are abundant in the arid and semiarid landscapes of the Western and Southwestern United States (U.S.). Connectivity of ephemeral and intermittent streams to the relatively few perennial reaches through runoff is a major driver of the ecohydrolog...
Impact of Leaching Conditions on Constituents Release from Flue Gas Desulfurization Gypsum (FGDG) and FGDG-Soil Mixture (JOURNAL)
The interest in using Flue Gas Desulfurization Gypsum(FGDG) has increased recently. This study evaluates the leaching characteristics of trace elements in "modern" FGDG (produced after fly ash removal) and FGDG-mixed soil (SF) under different environmental conditions using rece...
