Microbial Communities in Partially and Fully Treated Effluent of Three Nitrogen-Removing Biofilters
(ASCE, 2020)In the United States, 24% of single-family homes have on-site wastewater treatment systems (OWTS). Not only is the proportion much higher in some areas, but also most of the OWTS provide no nitrogen removal. An innovative ... -
Temporal Lags in Post-Rain Greenhouse Gas Cycling and Fluxes from Septic Leach Field Soils and Associated Greenhouse Gas Cycling Microbial Populations
(ASCE, 2020)Globally, one in six people depends on septic systems for onsite wastewater treatment; however, little is known about leach field system greenhouse gas (GHG) emissions and microbial GHG cycling. Methane (CH4), carbon dioxide ... -
Resilience of On-Site Wastewater Treatment Systems after Extreme Storm Event
(ASCE, 2020)In September 2013 an extreme (1000-year) storm event in north central Colorado produced over 40 cm rainfall in four days, resulting in widespread flooding. Along with damage to roads, bridges, housing, and sewers, ... -
Nitrogen Transformations and Microbial Characterization of Soils from Passive Nitrogen Removing Biofilters
(ASCE, 2020)To investigate spatial variability, regulation, and mass balances of N transformations in nitrogen-removing biofilters (NRBs), N2─N production and NO3−─N consumption were measured in suboxic incubations of nitrified percolate ... -
Biogeochemical Sequestration of Phosphorus in a Two-Layer Lignocellulose-Based Soil Treatment System
(ASCE, 2020)On-site wastewater treatment systems can contribute to the oversupply of phosphorus (P) to aquatic systems which represents a key factor for the development of eutrophic conditions and associated environmental issues, such ... -
Stormwater Management Options and Decision-Making in Urbanized Watersheds of Los Angeles, California
(ASCE, 2020)Hydrologic modeling is a crucial tool to understand the physical and hydrologic characteristics that contribute to water quality degradation in urban areas and the effectiveness of stormwater best management practices ... -
Dynamic Influent Generator for Alternative Wastewater Management with Urine Source Separation
(ASCE, 2020)The simulation of wastewater treatment plants allows obtaining predictive results when one needs to understand, evaluate, optimize, or design a plant. However, one of the bottlenecks of simulation feasibility is to obtain ... -
Modeling and Design Scenario Analysis of Long-Term Monitored Bioretention System for Rainfall-Runoff Reduction to Combined Sewer in Cincinnati, OH
(ASCE, 2020)Green infrastructure (GI) is a contemporary approach to the management of stormwater and limits its intrusion into wastewater collection systems. GI practices, such as bioretention systems, affect the local water cycle by ... -
Hydrobiogeochemical Function of Soil Based Onsite Wastewater Treatment Systems: Insights from High-Resolution O2 Imaging
(ASCE, 2020)Innovative/alternative onsite wastewater treatment systems (I/A OWTS) are increasingly installed to protect groundwater and surface water from excess nitrogen. Improved understanding of the relationships between hydraulic ... -
Bioretention System Enhancements for Nutrient Removal
(ASCE, 2020)Bioretention systems typically demonstrate limited nutrient treatment and often export nutrients just after installation. A variety of bioretention configurations were tested in duplicate field-scale mesocosms dosed with ... -
Integrated Decentralized Treatment for Improved N and K Recovery from Urine
(ASCE, 2020)Urine has been recognized as the main contributor of nitrogen (N), phosphorus (P), and potassium (K) at wastewater treatment plants, yet it makes up less than 1% of the volume. This study aimed to assess a novel decentralized ... -
A Pilot-Scale Hybrid Adsorption–Biological Treatment System for Nitrogen Removal in Onsite Wastewater Treatment
(ASCE, 2020)Onsite wastewater treatment systems (OWTS) are significant nonpoint sources of nutrients to surface and groundwater worldwide. Advanced OWTS are challenged by highly transient nutrient loads, long idle periods (e.g., during ... -
Barriers to Modeling the Hydrological Impact of Rainwater Harvesting in Urban Catchments
(ASCE, 2020)The increasing adoption of domestic rainwater harvesting (RWH) as a supplementary/alternative water source has created changes in the hydrology of many urban catchments. To achieve sustainable urban water management, there ... -
High-Resolution Energy Intensity Modeling to Improve Water Distribution System Performance
(ASCE, 2020)Water distribution systems can improve their sustainability by identifying and implementing the most energy-efficient scheme for water delivery, but this is difficult to determine for complex systems. A method proposed ... -
Performance Characterization of a Steam Distillation Process for Ammonium Recovery from Urine
(ASCE, 2020)The purpose of this study was to characterize the nitrogen recovery efficiency of a full-scale prototype nutrient recovery system that processes source-separated urine by the steam distillation of ammonia. Successful ... -
Evaluation of Stormwater Treatment Vault with Coanda-Effect Screen for Removal of Solids and Phosphorus in Urban Runoff
(ASCE, 2020)Catch basins commonly are used by cities as part of a stormwater management plan to remove sediment and associated contaminants from stormwater, keeping them in compliance with regulations. Recently, the city of Madison, ... -
Hydrologic Performance of a Permeable Pavement and Stormwater Harvesting Treatment Train Stormwater Control Measure
(ASCE, 2020)Stormwater runoff from urban development causes undesired impacts to surface waters, including discharge of pollutants, stream erosion, and loss of in-stream habitat. Stormwater control measures (SCMs), such as ponds, ... -
Multiyear Water Quality Performance and Mass Accumulation of PCBs, Mercury, Methylmercury, Copper, and Microplastics in a Bioretention Rain Garden
(American Society of Civil Engineers, 2019)A multiyear water quality performance study of a bioretention rain garden located along a major urban transit corridor east of San Francisco Bay was conducted to assess the efficacy of bioretention rain gardens to remove ... -
Characterization of Street Sweeping Material for Addressing Total Maximum Daily Waste Load Allocations
(American Society of Civil Engineers, 2019)Municipal separate storm sewer system (MS4) permittees are increasingly required to reduce pollutant of concern (POC) loadings from their service areas to achieve waste load allocations (WLAs) assigned as part of total ... -
Assessment of Annual Water-Balance Models for Diverse Indian Watersheds
(American Society of Civil Engineers, 2019)Hydrological responses of a watershed are often cumbersome to identify because they exhibit spatiotemporal variation. Rather, it is interesting to observe the hydrologic responses of a basin at a microlevel scale. Thus, a ...
