A resilience framework for chronic exposures: water quality and ecosystem services in coastal social-ecological systems (PRESENTATION)
We outline a tailored resilience framework that applies ecosystem service concepts to coastal social-ecological systems (SES) affected by water quality degradation. Unlike acute coastal disturbances such as hurricanes or oil spills, water quality issues, particularly those relate...
Marsh soil responses to tidal water nitrogen additions contribute to creek bank fracturing and slumping (PRESENTATION)
Large-scale dissolved nutrient enrichment can cause a reduction in belowground biomass, increased water content of soils, and increased microbial decomposition, which has been linked with slumping of low marsh Spartina vegetation into creeks, and ultimately marsh loss. Our study ...
The Cyanobacteria Assessment Network - Recent Success in Harmful Algal Bloom Detection (NEWSLETTER ARTICLE)
Cyanobacteria blooms, which can become harmful algal blooms (HABs), are a huge environmental problem across the United States. They are capable of producing dangerous toxins that threaten the health of humans and animals, quality of drinking water supplies, and the ecosystem in w...
Using National Coastal Assessment Data to Model Estuarine Water Quality at Large Spatial Scales. (PRESENTATION)
The water quality of the Nation’s estuaries is attracting scrutiny in light of population growth and enhanced nutrient delivery. The USEPA has evaluated water quality in the National Coastal Assessment (NCA) and National Aquatic Resource Surveys (NARS) programs. Here we rep...
Assessment of Dry Wells for Stormwater Capture and Aquifer Recharge in the Arid and Semi-Arid Southwest (PRESENTATION)
GOAL: to evaluate the utility of innovative, distributed, low impact development (LID) infrastructure and best management practices (BMPs) for wet weather capture and drinking water aquifer recharge in the arid and semi-arid southwestern USA OBJECTIVES: Design, build, monitor t...
Suspect Screening and Non-Targeted Analysis of Drinking Water Using Point-Of-Use Filters (JOURNAL)
Monitored contaminants in drinking water represent a small portion of the total compounds present, many of which may be relevant to human health. To understand the totality of human exposure to compounds in drinking water, broader monitoring methods are imperative. In an effort t...
Nekton use of oyster occupied habitats in two coastal ponds in Rhode Island (PRESENTATION)
Restoration of oyster habitat aims to expand or preserve ecosystem services including increased secondary production of the community. We compare density, biomass, and average standing stock of nitrogen and carbon in seasonal fish and invertebrate collections in Ninigret and Gree...
Changes in nitrogen isotope ratios in estuarine biota following nutrient reductions to Narragansett Bay (PRESENTATION)
Increased nutrient inputs globally have resulted in widespread eutrophication to many coastal water bodies including Narragansett Bay. Efforts to reduce point source nitrogen load¬ings from waste water treatment facilities (WWTFs) and combined sewer overflows (CSOs) started i...
The Lives and Times of the Narragansett Bay Benthos: Biodiversity Trends over 182 Years (PRESENTATION)
Narragansett Bay has high benthic invertebrate biodiversity that supports many ecosystem functions and services. A master list was compiled of all benthic species collected from the Bay beginning in 1862, including a U.S. Bureau of Commercial Fisheries survey in 1871 and studies ...
Changes to habitats over time in Narragansett Bay and setting management targets using BCG approaches (PRESENTATION)
We compare changes in the distributions of seagrass, benthic, macroalgal, saltmarsh, and shellfish habitat in Narragansett Bay (U.S.A.) since the 1700s to changes in stressors and management decisions over the same time period, and describe a method that management programs can u...
Using BCG as a framework for setting goals and communicating progress toward those goals (PRESENTATION)
This 5 minute Lightning Talk will discuss the benefits of stakeholder-supported quantitative targets in measuring progress, and will describe the Biological Condition Gradient (BCG) as one way to develop these quantitative targets.
The Effects of Source Water Quality on Drinking Water Treatment Costs: A Review and Synthesis of Empirical Literature - slides (PRESENTATION)
Watershed protection, and associated in situ water quality improvements, has received considerable attention as a means of mitigating health risks and avoiding expenditures at drinking water treatment plants (DWTPs). In this presentation, we review the literature linking raw wate...
Comparisons of Spatial Predictions of Conductivity on a Stream Network in an Appalachian Watershed (PRESENTATION)
We made spatial predictions of specific conductance based on spatial stream network (SSN) modeling to compare conductivity measurements of components of the network, such as headwaters, tributaries, and mainstem, which have different spatial extents in a study Appalachian watersh...
How the distribution of anthropogenic nitrogen has changed in Narragansett Bay (RI, USA) following major reductions in nutrient loads (PRESENTATION)
Over the past decade, nitrogen (N) loads to Narragansett Bay have decreased by about 65%. These reductions were the direct result of multiple sewage treatment plant upgrades to tertiary treatment, a process which employs N removal. Here we document ecosystem response to the N red...
Quantifying the Recreational Value of an Estuary: A Transferable Method (PRESENTATION)
Coastal water quality impairment (excess bacteria and nutrients) due to failed septic systems and cesspools is a major concern for Cape Cod, Massachusetts because of its waters’ high economic and social value. High bacteria levels can lead to closures at bathing beaches. Nu...
How many people use the Three Bays estuary system for recreation? (COMMUNICATION PRODUCT)
Little is known about recreational use on estuaries like Three Bays. We are testing a practical approach to quantify recreational use of the Three Bays estuary system so we can better understand how many people are affected by changes in environmental quality. This involves count...
Metabolic Disruption Early in Life is Associated With Latent Carcinogenic Activity of Dichloroacetic Acid in Mice (JOURNAL)
Early-life environmental factors can influence later-life susceptibility to cancer. Recent evidence suggests that metabolic pathways may mediate this type of latency effect. Previously, we reported that short-term exposure to dichloroacetic acid (DCA) increased liver cancer in mi...
People and water: Exploring the social-ecological condition of watersheds of the United States (JOURNAL)
A recent paradigm shift from purely biophysical towards social-ecological assessment of watersheds has been proposed to understand, monitor, and manipulate the myriad interactions between human well-being and the ecosystem services that watersheds provide. However, large-scale, q...
Assessing ecological conditions in the Great Lakes Connecting Channels using National Coastal Condition Assessment protocol (PRESENTATION)
The EPA Office of Water’s National Coastal Condition Assessment (NCCA) helps satisfy the assessment and antidegradation provisions of the Clean Water Act by estimating water, sediment, and benthic quality conditions in the Great Lakes nearshore on a five-year cycle starting...
Retrospective Surveillance of Wastewater To Examine Seasonal Dynamics of Enterovirus Infections (JOURNAL)
Enteroviruses are RNA viruses that are responsible for both mild gastroenteritis and mild respiratory illnesses as well as debilitating diseases such as meningitis and myocarditis. The disease burden of enteroviruses in the United States is difficult to assess because most infect...
The acute toxicity of major ion salts to Ceriodaphnia dubia: III. Mathematical models for mixture toxicity (JOURNAL)
Based on previous research on the acute toxicity of major ions (Na+, K+, Ca2+, Mg2+, Cl, SO42, and HCO3/CO32) to C. dubia, two mathematical models were developed for predicting the LC50 for any ion mixture, excluding those dominated by K toxicity. One model addresses a mechanism...
Aquifer Restoration after Uranium Recovery (COMMUNICATION PRODUCT)
In-situ recovery (ISR) of uranium is a mining practice that uses groundwater. First, wells are drilled into a uranium-bearing aquifer. Leaching fluids are injected into the wells to dissolve the uranium ore into the groundwater, and then the uranium is recovered by extracting the...
