Chlorine and monochloramine disinfection of Legionella pneumophila colonizing copper and PVC drinking water biofilms (JOURNAL)
Building water systems (BWSs) promote the regrowth and survival of opportunistic pathogens, such as Legionella pneumophila, especially within biofilms (BFs), where most drinking water (DW) microbes reside. However, compared to their planktonic (PL) form, disinfection efficacy fo...
Coastal habitat change and marine megafauna behavior: Florida manatees encountering reduced food provisions in a prominent winter refuge (JOURNAL)
A decline in submerged aquatic vegetation (SAV) within Florida’s spring-fed thermal refuges raises questions about how these systems support winter foraging of Florida manatees Trichechus manatus latirostris. We analyzed telemetry data for 12 manatees over 7 yr to assess th...
Collaborative multi-agency characterization of reservoirs targeted for GLLA remediation in St. Louis River Area of Concern (AOC) (PRESENTATION)
A multi-agency, collaborative effort was completed in the fall of 2016 and summer of 2017 to provide a baseline assessment of pre-remedial conditions. Multiple state and federal agencies (U.S. Army Corps of Engineers (USACE), U.S. EPA ORD, U.S. EPA GLNPO, USGS and Minnesota Pollu...
Comparison of Measured and Simulated Urban Soil Hydrologic Properties (JOURNAL)
Urban communities use hydrologic models to plan for and assess the effectiveness of stormwater control measures. Although emphasis is placed on soils as permeable surfaces that regulate the rainfall-runoff process, representative soil hydrologic parameters for urban areas are rar...
Comparison of the Sustainability of Bean Production Systems Based on Emergy and Economic Analyses (JOURNAL)
To address increasing demand during the last decades, bean producers have intensified agricultural activities by increasing the use of industrial inputs. Such intensification can impose environmental as well as economic risks to fragile ecosystems. Emergy and economic analyses we...
Denitrification in the Hyporheic Zone during Base Flow (PRESENTATION)
Excess nitrogen (N) and phosphorus (P) from human activities have contributed to degradation of coastal waters globally. A growing body of work suggests that hydrologically restoring streams and rivers in agricultural and urban watersheds has potential to increase N and P retenti...
Development of a spatially complete floodplain map of the conterminous United States using random forest (JOURNAL)
Floodplains perform several important ecosystem services, including storing water during precipitation events and reducing peak flows, thus reducing flooding of downstream communities. Understanding the relationship between flood inundation and floodplains is critical for ecosyst...
Environmental fate of multiwalled carbon nanotubes and graphene oxide across different aquatic ecosystems (JOURNAL)
The industrial use and widespread application of carbon-based nanomaterials have caused a rapid increase in their production over the last decades. However, toxicity of these materials is not fully known and still being investigated for potential human and ecological health risks...
Evaluating the Ecosystem Services and Benefits of Wetland Restoration by Use of the Rapid Benefit Indicators Approach (JOURNAL)
Wetlands in urban and urbanizing areas are often smaller, more degraded, and subject to more stressors than those in undeveloped locations. Their restored level of functioning may never equal that of a site in an undisturbed landscape. Yet, the social benefits from restoring thes...
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...
Extended persistence of general and cattle-associated fecal indicators in marine and freshwater environment (JOURNAL)
Fecal contamination of recreational waters with cattle manure can pose a risk to public health due to the potential presence of various zoonotic pathogens. Fecal indicator bacteria (FIB) have a long history of use in the assessment of recreational water quality, but FIB quantific...
Floodplain Waste Water Re-Use and Indirect Discharge (COMMUNICATION PRODUCT)
This whitepaper is informational for those interested research and activities related to the re-use and practice of discharging treated effluent into floodplain river systems. It describes what indirect discharge is, how the practice is distributed in the U.S. and what current re...
Georgeite: A Rare Copper Mineral with Important Drinking Water Implications (JOURNAL)
Since the implementation of the Lead and Copper Rule, a large amount of research has been conducted on copper corrosion and solubility, including the establishment of the “cupric hydroxide model”. This conceptual model describes the temporal aging and associated solubility change...
Holistic Analysis of Urban Water Systems in the Greater Cincinnati Region: (1) Life Cycle Assessment and Cost Implications (JOURNAL)
Urban water and wastewater utilities are striving to improve their environmental and economic performances due to multi-challenges such as increasingly stringent quality criterion, aging infrastructure, constraining financial burden, growing urban population, climate challenges a...
Holistic Analysis of Urban Water Systems in the Greater Cincinnati Region: (2) Resource Use Profiles by Emergy Accounting Approach (JOURNAL)
With increasing populations, mounting environmental pressures and aging infrastructure, urban water and wastewater utilities have to make management decisions limited by both economic and environmental constraints. The challenges facing urban water systems can no longer be sustai...
In utero exposure to Simvastatin reduces postnatal survival and permanently alters reproductive tract development in the CRL:CD(SD) male rat (JOURNAL)
We showed previously that in utero exposure to the cholesterol-lowering drug simvastatin (SMV) during sex differentiation lowers fetal lipids and testicular testosterone production (T Prod) in Hsd:SD rats. Here, the effects of SMV on fetal lipids and T Prod in Crl:CD(SD) rats wer...
Introducing the Freshwater Explorer: A national view of background and measured conductivity- Abstract (PRESENTATION)
The Freshwater Explorer is an interactive map interface that allows users to compare predicted natural background with measured ambient stream conductivity. It allows users to visualize the relative freshness of streams across the contiguous United States or within a network of s...

Leak, Purge, and Gas Permeability Testing to Support Active Soil-Gas Sampling (PUBLISHED REPORT)
Active soil-gas sampling has been used as a reconnaissance method in support of soil and groundwater sampling of volatile and biodegradable organic compounds for over 30 years. More recently, soil gas sampling has been used directly to evaluate risk posed by vapor migration from ...
Light Absorption of Organic Carbon and its Sources at Southeastern U.S. Locations in Summer (JOURNAL)
Light-absorbing organic carbon (OC), also referred to as “brown carbon” (BrC), has been intensively investigated in biomass burning (BB) impacted atmospheres. However, other BrC sources (e.g., secondary formation) are rarely studied in ambient aerosols. In the current work, forty...
Modeling framework for simulating concentrations of solute chemicals, nanoparticles, and solids in surface waters and sediments: WASP8 Advanced Toxicant Module (JOURNAL)
Toxicant concentrations in surface waters and sediments are of environmental concern due to their potential impacts on ecological and human receptors. Numerical, process-based, mass balance models are one way to understand a system and its governing processes, assist in supportin...
Monitoring the performance of urban green infrastructure using a tensiometer approach (JOURNAL)
