Agricultural best management practices (BMPs) reduce non-point source pollution from cropland. Goals for BMP adoption and expected pollutant load reductions are often specified in water quality management plans to protect and restore waterbodies; however, estimates of needed load...

Assessments of the environmental behavior of highly hydrophobic nonionic organic chemicals have large uncertainties because the models used to predict their behavior were parameterized using training sets of chemicals with much lower hydrophobicities. Bioaccumulation of a few hi...

Population growth and unsustainable agricultural and industrial activities have led to a decrease in water quality and availability, causing ecological risks and challenging drinking water treatment plants to provide clean water. Many techniques are available for monitoring known...

The number of abandoned mines globally is in the hundreds of thousands, with many mines capable of generating acidity, increasing metal solubility, and degrading environmental quality. Biochar may play a role in alleviating acidity and heavy metal contamination by increasing soi...

There is a need for fast, efficient, and cost-effective hazard identification and characterization of chemical hazards. This need is generating increased interest in the use of zebrafish embryos as both a screening tool and an alternative to mammalian test methods. A Collaborativ...

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...

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...

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...

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...

We compare the performance of two hypothesis test statistical approaches currently used in U.S. water regulatory programs to interpret the reproduction endpoint for the Ceriodaphnia dubia survival and reproduction aquatic toxicity test. These statistical approaches are (1) the w...

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...

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...

We have used historical time series data for flow on the Ohio River and developed a theoretically rational means of characterizing the unique hydrologic conditions that coincided with the record-setting HAB in 2015. Two statistical techniques were used to derive significant model...

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...

The primary objective of this pilot-scale project was to demonstrate and validate anaerobic membrane bioreactor (AnMBR) technology for domestic wastewater treatment. Specific objectives associated with this project included: 1) demonstrate the effectiveness of AnMBR at treating s...

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...

A radiological release from a radiological dispersal device (RDD) or an improvised nuclear device (IND) has the potential to contaminate a vast area both near the dispersal epicenter and via atmospheric deposition of small particles containing the more volatile contaminants. Rapi...

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...

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...

Worldwide studies show 80%–90% of all sediments eroded from watersheds is trapped within river networks such as reservoirs, ponds, and wetlands. To represent the impact of impoundments on sediment routing in watershed modeling, Soil and Water Assessment Tool (SWAT) develope...

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...

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...

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...

Presentation comparing health advisories and possible health effects of harmful algal blooms (HABS)

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...
