Presentation at a Groundwater Symposium sponsored by Region 7, Lenexa, KS.
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...
US Environmental Protection Agency Efforts to address Harmful Algal Blooms (HABs) Impacting Drinking and Recreational Waters (NEWSLETTER ARTICLE)
This is a short article for a European cyanobacteria newsletter that discusses EPA efforts in the following areas: toxin monitoring in public water systems, toxin guidance values in drinking and recreational waters, and research in the areas of treatment, monitoring, methods deve...
Child environmental exposures to water and sand at the beach: Findings from studies of over 60,000 subjects at 12 beaches (JOURNAL)
Swimming and recreating in lakes, oceans, and rivers is common, yet the literature suggests children· may be at greater risk of illness following such exposures. These effects might be due to differences in immunity or differing behavioral factors such as poorer hygiene, l...
Development of a Methodology for the Derivation of Aquatic Plant Water Quality Criteria (PUBLISHED REPORT)
Aquatic plants form the base of most aquatic food chains, comprise biodiversity-building habitats and are functionally important in carbon assimilation and oxygen evolution. The USEPA, as stated in the Clean Water Act, establishes criterion values for various pollutants found in ...
In vivo and in vitro methods for evaluating soil arsenic bioavailability: relevant to human health risk assessment (JOURNAL)
Arsenic (As) is the most frequently occurring contaminant on the priority list of hazardous substances, which lists substances of greatest public health concern to people living at or near U.S. National Priorities List site. Accurate assessment of human health risks from exposure...
Immunoprevalence to Six Waterborne Pathogens in Beachgoers at Boquerón Beach, Puerto Rico: Application of a Microsphere-Based Salivary Antibody Multiplex Immunoassay (JOURNAL)
Waterborne infectious diseases are a major public health concern worldwide. Few methods have been established that are capable of measuring human exposure to multiple waterborne pathogens simultaneously using non-invasive samples such as saliva. Most current methods measure expos...
Harmful Algae Bloom Occurrence in Urban Ponds: Relationship of Toxin Levels with Cell Density and Species Composition (JOURNAL)
Retention ponds constructed within urban watershed areas of high density populations are common as a result of green infrastructure applications. Several urban ponds in the Northern Kentucky area were monitored for algal community (algae and cyanobacteria) from October 2012 to Se...
Satellite sensor requirements for monitoring essential biodiversity variables of coastal ecosystems (JOURNAL)
The biodiversity and high productivity of coastal terrestrial and aquatic habitats are the foundation for important benefits to human societies around the world. These globally distributed habitats need frequent and broad systematic assessments, but field surveys only cover a sma...
Holistic Analysis of the Urban Water Systems in Greater Cincinnati Region (PRESENTATION)
Urban water and wastewater systems with two utilities in Greater Cincinnati region were evaluated as a case study to elucidates a bigger picture of a typical centralized urban water system. Two different integrated assessment metrics were used to analyze the same system. LCA an...
Occurrence and in vitro bioactivity of estrogen, androgen, and glucocorticoid compounds in a nationwide screen of United States stream waters (JOURNAL)
In vitro bioassays are sensitive, effect-based tools used to quantitatively screen for chemicals with nuclear receptor activity in environmental samples. We measured in vitro estrogen (ER), androgen (AR), and glucocorticoid receptor (GR) activity, along with a suite of chemical a...
Perfluoroalky acids-induced liver steatosis: Effects on genes controlling lipid homeostasis (JOURNAL)
Abstract Persistent presence of perfluoroalkyl acids (PFAAs) in the environment is due to their extensive use in industrial and consumer products, and their slow decay. Biochemical tests in rodent demonstrated that these chemicals are potent modifiers of lipid metabolism and caus...
Chemical-agnostic hazard prediction: statistical inference of in vitro toxicity pathways from proteomics responses to chemical mixtures (JOURNAL)
Toxicity pathways have been defined as normal cellular pathways that, when sufficiently perturbed as a consequence of chemical exposure, lead to an adverse outcome. If an exposure alters one or more normal biological pathways to an extent that leads to an adverse toxicity outcome...
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...
Coliphages and gastrointestinal illness in recreational waters: pooled analysis of six coastal beach cohorts (JOURNAL)
BACKGROUND: Coliphages have been proposed as indicators of fecal contamination in recreational waters because they better mimic the persistence of pathogenic viruses in the environment and wastewater treatment than fecal indicator bacteria. We estimated the association between co...
Need to improve SWMM's subsurface flow routing algorithm for green infrastructure modeling (PRESENTATION)
SWMM can simulate various subsurface flows, including groundwater (GW) release from a subcatchment to a node, percolation out of storage units and low impact development (LID) controls, and rainfall derived inflow and infiltration (RDII) at a node. Originally, the subsurface flow...
