An inventory of continental U.S. terrestrial candidate ecological restoration areas based on landscape context (JOURNAL)
Landscape context is an important factor in restoration ecology, but the use of landscape context for site prioritization has not been as fully developed. We used morphological image processing to identify candidate ecological restoration areas based on their proximity to existin...
A keyword approach to finding common ground in community-based definitions of human well-being (JOURNAL)
Ecosystem-based management involves the integration of ecosystem services and their human beneficiaries into decision making. This can occur at multiple scales; addressing global issues such as climate change down to local problems such as flood protection and maintaining water q...
The Role of Shellfish Aquaculture in Reduction of Eutrophication in an Urban Estuary (JOURNAL)
Land-based management has reduced nutrient discharges; however, many coastal waterbodies remain impaired. Oyster “bioextraction” of nutrients and how oyster aquaculture might complement existing management measures in urban estuaries was examined in Long Island Sound,...
Assessing the Nation's Coastal Waters....Better (PRESENTATION)
The USEPA has been assessing estuarine and coastal condition in the United States since 1999 via the National Coastal Assessment (NCA) and National Aquatic Resources Surveys (NARS) programs. Approximately 1500 randomly selected coastal sites were surveyed annually during summers ...
Understanding the Impacts and Meaning of Maintaining Detectable Disinfection Residuals in Drinking Water Distribution Systems: Controlling Waterborne Pathogens, Disinfection Byproducts, Organic Chloramines, and Nitrification (PRESENTATION)
: EPA Region 6, in collaboration with the Office of Research and Development and Office of Water (OW) in Cincinnati, Ohio, and the Louisiana Department of Health and Hospitals (LDHH), proposes a drinking water research project to understand how maintaining various drinking water...
Retrospective Case Study in Northeastern Pennsylvania, Study of the Potential Impacts of Hydraulic Fracturing On Drinking Water Resources (PUBLISHED REPORT)
This report describes the retrospective case study for northeastern Pennsylvania, which was conducted in Bradford and Susquehanna Counties where some of the most intensive unconventional gas production from the Devonian-age Marcellus Shale has occurred. Gas production from the M...
Retrospective Case Study in Southwestern Pennsylvania, Study of the Potential Impacts of Hydraulic Facturing on Drinking Water Resources (PUBLISHED REPORT)
This report describes the retrospective case study for southwestern Pennsylvania, which was conducted in Amwell, Cross Creek, Hopewell, and Mount Pleasant Townships in Washington County, locations that have witnessed unconventional gas production from the Devonian-age Marcellus S...
Retrospective Case Study in Killdeer, North Dakota, Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources. (PUBLISHED REPORT)
This report describes the retrospective case study conducted near Killdeer, Dunn County, North Dakota. The Killdeer study area is the location of historical oil and gas production, with current unconventional oil and gas production occurring in the late Devonian/early Mississipp...
Retrospective Case Study in Wise County, Texas, Study of the Potential Impacts of Hydraulic Fracturing on Drinking Water Resources (PUBLISHED REPORT)
This report describes the retrospective case study in north central Texas, conducted at three locations in Wise County where both conventional and unconventional gas production occurred in the past. Currently unconventional gas production occurs from the Mississippian-aged Barne...
Retrospective Case Study in the Raton Basin, Colorado, Study of hte Potential Impacts of Hydraulic Fracturing on Drinking Water Resources. (PUBLISHED REPORT)
This report describes the retrospective case study that was conducted in the Colorado portion of the Raton Basin, located within Las Animas and Huerfano counties. These locations are the focus of unconventional gas production of coalbed methane (CBM) from several coal-bearing st...
CHALLENGES IN MAINTAINING DRINKING WATER QUALITY AT THE TAP: CONTAMINATION WITH TOXIC LEAD (PRESENTATION)
Aging drinking water infrastructure in the US was given a grade of D (poor) by the American Society of Civil Engineers, and was voted as the most urgent of all societal infrastructure challenges. Legacy lead pipe, leaded solder and/or leaded brass are a particularly notorious old...
Green infrastructure and its catchment-scale effects: an emerging science (JOURNAL)
Urbanizing environments alter the hydrological cycle by redirecting stream networks for stormwater and wastewater transmission and increasing impermeable surfaces. These changes thereby accelerate the runoff of water and its constituents following precipitation events, alter evap...
Quantifying Spatially Integrated Floodplain and Wetland Systems for the Conterminous US (PRESENTATION)
Wetlands interact with other waters across a variable connectivity continuum, from permanent to transient, from fast to slow, and from primarily surface water to exclusively groundwater flows. Floodplain wetlands typically experience fast and frequent surface and near-surface gro...
Landscape Conservation of Aquatic Habitats Promotes Watershed-scale Biological, Biogeochemical, and Hydrological Functions (PRESENTATION)
Wetlands are exceptionally productive landscape features that provide critical habitat for endemic species, threatened/endangered and migratory animals, store floodwaters and maintain baseflows in stream systems, recharge groundwaters, and biogeochemically and physically affect n...
The Application and Usefulness of Economic Analyses for Water Quality Management in Coastal Areas (JOURNAL)
Economic studies are increasingly sought as tools to contribute to water quality management in estuaries and coastal communities, yet little is known about how the results from existing studies have been received and utilized by the organizations who solicited them. We interviewe...
Living Shoreline on Martha's Vineyard: Monitoring & Assessing Marsh Stabilization, Restoration Benefits, and Nitrogen Removal (PRESENTATION)
Salt marshes provide a unique intertidal habitat between land and sea, making them one of the most diverse and productive ecosystems on Earth. Their ecosystem services are often undervalued, and are being degraded by multiple stressors such as human development and climate change...
