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...
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 ...
Evaluation of Biochar to Enhance Green Infrastructure for Removal of Heavy Metals in Stormwater (PRESENTATION)
The changes in the natural North American drainage system over the centuries have given rise to significant modern ecological impacts during high precipitation events. Contaminated stormwater runoff is of particular concern during these events. Urban development increases imperme...
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...
Measuring the pulse of urban green infrastructure: vegetation dynamics across residential landscapes (PRESENTATION)
Vegetation can be an important component of urban green infrastructure. Its structure is a complex result of the socio-ecological milieu and management decisions, and it can influence numerous ecohydrological processes such as stormwater interception and evapotranspiration. Despi...
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...
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...
Water Network Tool for Resilience (WNTR) User Manual (PUBLISHED REPORT)
The Water Network Tool for Resilience (WNTR) is a new Python package designed to simulate and analyze resilience of water distribution networks to a variety of disaster scenarios. WNTR can help water utilities to explore the capacity of their systems to handle disasters and gui...
Resource Recovery-based Sustainable Water Systems - the City of Tomorrow (PRESENTATION)
Urban water systems are an example of complex, dynamic human-environment coupled systems which exhibit emergent behaviors that transcends individual scientific disciplines. To address the complexities associated with municipal water issues there is a need to shift from our tradi...
Detention Outlet Retrofit Improves the Functionality of Existing Detention Basins by Reducing Erosive Flows in Receiving Channels (JOURNAL)
Journal Article
EPA Office of Research and Development Green Infrastructure Research (PRESENTATION)
This presentation provides an overview introduction to the USEPA Office of Research and Development (ORD)'s ongoing green infrastructure (GI) research efforts for stormwater management. GI approaches that increase infiltration, evapotranspiration, and rainwater harvesting offer ...
Decision Support System for Aquifer Recharge (AR) and Aquifer Storage and Recovery (ASR) Planning, Design, and Evaluation - Principles and Technical Basis (PUBLISHED REPORT)
Aquifer recharge (AR) is a technical method being utilized to enhance groundwater resources through man-made replenishment means, such as infiltration basins and injections wells. Aquifer storage and recovery (ASR) furthers the AR techniques by withdrawal of stored groundwater at...
Corexit 9500 Enhances Oil Biodegradation and Changes Active Bacterial Community Structure of Oil-Enriched Microcosms (JOURNAL)
While COREXIT 9500 is widely applied after oil spills for its reported dispersing activity, there is still a debate on the effectiveness on enhancing oil biodegradation and its potential toxic effect on microbial communities. To better understand the impact of COREXIT 9500 on the...
