Refined Model Provides a Screening Tool to Understand Exposure to Contaminants from Incidental Wastewater Reuse

Refinement of the existing national-scale “de facto reuse incidence in our nation’s consumable supply” (DRINCS) model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the Shenandoah River watershed. The model results can be accessed in a companion...

River Continuum Concept Ecological Limit Functions for Fish and Benthic Data in Virginia

The ecological limit functions (ELF) developed in cooperation with the Virginia Department of Environmental Quality (DEQ) are a graphical representation of the current and historical state of aquatic biota in Virginia streams.  The goal of this study was to quantify the potential species richness and habitat response to flow alteration using available long-term ecological data. Fish and...

Sea Level and Storm Hazards: Past and Present

Sea level and Storm Hazards: Past and Present is a multidisciplinary study of past changes in sea level. Prehistoric shorelines can be used as a baseline for current and future sea level changes under warmer-than-present climate. Emphasis is placed on looking at sea levels during warm periods of the last 500,000 years as well as how base level changes increase the risk of coastal inundation...

Assessment of Unconventional Energy Potential of Methane Released from Active and Abandoned Mines

Large underground coal mines, especially longwall mines, disturb an extensive layer of strata overlying and underlying the mined coal seam due to induced stresses and due to collapse of the coal-bearing strata into the void left from mined coal. This volume of strata disturbed by mining is termed as the gas emission zone, which often contains other gassy coal seams of non-economic value, thin...

Macrofossil and Sediment Processing Laboratory

In the Macrofossil and sediment processing lab we analyze the physical, biological, and geochemical characteristics of peat and sediment samples collected from lake, wetland, and peat cores as proxies for past changes to these depositional environments on timescales of decades to millennia. We primarily study terrestrial wetland ecosystems from subtropical to arctic regions in order to...
