Living shorelines and nitrogen mitigation on Martha's Vineyard, MA (PRESENTATION)
Increased human development along the coast and the subsequent increased delivery of excess nutrients to estuarine waterbodies can have combined deleterious effects on salt marsh ecosystems. An increasingly popular shoreline stabilization technique is the use of a living shorelin...
Green Infrastructure Monitoring at Edison Environmental Center: Permeable Pavement and Rain Garden Demonstration Site (PRESENTATION)
The Environmental Protection Agency’s Edison Environmental Center (EEC) has a research and demonstration permeable parking lot comprised of three different permeable systems: permeable asphalt, pervious concrete and permeable interlocking concrete pavers. There is also an a...
U.S. EPA National Stormwater Calculator: City of Birmingham, AL. Demonstration (PRESENTATION)
Stormwater discharges continue to cause impairment of our Nation’s waterbodies. In order to reduce impairment, EPA has developed the National Stormwater Calculator (SWC) to help support local, state, and national stormwater management objectives and regulatory efforts to re...
Comparison of two methods for the enumeration of Legionella pneumophila from potable water samples (PRESENTATION)
One-liter water samples were collected from a simulated home plumbing system in sterile polypropylene bottles containing sodium thiosulfate. A portion of each sample was analyzed using Legiolert according to the manufacturer instructions (10 ml of sample added to 90 ml of diluent...
Use of passive samplers for the detection of extra cellular algal toxins in stream mesocosms, lakes and streams (PRESENTATION)
The purpose of this study is to evaluate SPATTs and LF nsPSDs to determine their performance in determining extracellular algal toxins in both stream mesocosms and within Lake Harsha and its downstream habitats. PSDs were deployed at the end of 16 different stream mesocosms and ...
From Assessments to Decisions: How to Leverage Bayesian Networks (PRESENTATION)
Bayesian networks provide powerful and flexible modeling platforms for examining uncertainty and making inferences. They are especially useful for developing models that reflect causal issues such as how a stressor might impact an environmental endpoint of concern or how a decisi...
PFAS Removal Using Household Water Treatment Systems: Point-of-use (POU)/Point-of-entry (POE) - Cincinnati (PRESENTATION)
Per- and Poly- fluoroalkyl Substances (PFAS) contamination of groundwater sources in the U.S. is a widespread problem for the drinking water industry. To assist property owners and limit exposure of PFASs in residential drinking water systems, U.S. EPA conducted treatability stud...
Ecological Effects of Wildland Fire: Tradeoffs for Delivery of Ecosystem Services (PRESENTATION)
Fire is a vital process for sustained ecosystem functioning, providing habitat vitality and renewal through recolonization of new populations and succession of fire-tolerant species. Twentieth Century fire management practices have shown that removal of fire from fire-adapted eco...
A Health and Ecological Systems Framework for Vector-Borne Diseases in Puerto Rico (PRESENTATION)
Environmental, social and economic factors can influence public health, but the interactions can be difficult to understand and anticipate. A systems context, that is, a conceptual approach that simultaneously considers environmental, social and economic factors, is essential. Pr...
Evaluation of Equilibrium Passive Sampling Polymers for Monitoring Munition Constituents in Aquatic Systems. (PRESENTATION)
Objectives. A wide array of military munition constituents are present in water bodies surrounding historically deposited unexploded ordnance. A common approach for monitoring explosive constituents involves the collection of large quantities of discrete water samples combined wi...
Highlights from EPA's Wildland Fire Heath Research (PRESENTATION)
This presentation is part of the “Ecological, Human Health, Economic and Social Impacts of Wildland Fires” session. This presentation will highlight the health impacts of wildland fire smoke exposure, and the various facets of ORD’s wildland fire and health rese...
Social science research on Cape Cod: Case studies in Three Bays watershed (PRESENTATION)
We apply a decision-making process to guide watershed managers in meeting national water quality mandates while also considering pertinent ecological, social, and economic factors. Results show that technological advances in controlling household nitrogen sources could provide lo...
Solutions-Driven Research: Applying Translational Science Approaches to Research to Address Real-World Problems (PRESENTATION)
There are several complex or “wicked” problems related to air, water, and soil that impact ecosystems and communities both domestically and abroad. Many of these problems are aligned with US EPA’s mission to protect human health and the environment. Addressing t...
Landscape structure and land use affects estuarine benthic invertebrates in the Virginian Biogeographic Province, USA (PRESENTATION)
Estuaries are dynamic transition zones linking freshwater and oceanic habitats. These productive ecosystems are threatened by a variety of stressors including human modification of coastal watersheds. In this study we examined potential linkages between estuarine condition and...
THE ECOSYSTEM SERVICES GRADIENT AND THE BIOLOGICAL CONDITION GRADIENT LINK CHANGES IN BENEFITS AND BIOLOGY TO INCREASING STRESS IN AQUATIC SYSTEMS (PRESENTATION)
Characterization of ecosystem services can be a valuable element of Ecosystem Based Management in identifying meaningful measures of ecosystem change, understanding the natural resource gains or losses associated with changing ecosystem conditions, and communicating those benefit...
Historical context of the Tier 1 Submerged Aquatic Vegetation mapping efforts in Narragansett Bay RI. (PRESENTATION)
Rooted submerged aquatic vegetation (SAV) is an ecologically important habitat, and SAV loss is considered an indicator of nutrient pollution in estuaries. Therefore, the Narragansett Bay Estuary Program (responsible for producing technical reports on the state of the Narraganset...

The Economic Value of Recreation and Coastal Water Quality in New England (PRESENTATION)
Nutrient over-enrichment is a significant problem in coastal waterbodies, particularly estuaries, across the United States. At the Atlantic Ecology Division of the U.S. EPA, we are working on an interdisciplinary project to understand various aspects of the impacts of nutrient ov...
Challenges of Thermal Remediation at Superfund Sites (PRESENTATION)
In recent years, the use of in situ thermal remediation technologies at Superfund Sites in the United States has increased substantially. With this, comes new challenges while the overall goal of reducing contamination to very low levels remains. My experience has been that the...
Landforms of Urban Watersheds (PRESENTATION)
Landforms – specifically hillslope forms and resulting processes – couple terrestrial and aquatic systems. In urban watersheds, soil is commonly moved and shaped to accomplish land and water management objectives of residents and municipal agencies. Here, we ask, how ...
