As part of the Grantee Kickoff Meeting for recent STAR award recipients, this presentation will cover ORD research updates on pathogen log-reduction targets (LRTs) for onsite non-potable water systems.&nbsp; Topics include collaboration to assess the &quot;state of the science&qu...

Targeted chemical analyses, non-targeted analyses, and bioanalytical tools each provide a unique but incomplete understanding of the chemicals in a sample.  The US Environmental Protection Agency and US Geological Survey are collaborating to examine the sources, fates, and potent...

The analysis of contaminants of emerging concern (CECs) has been an ongoing priority due to their potential for adverse effects on human health and wildlife. With many tens of thousands of chemicals in use today, prioritizing specific chemicals or mixtures of chemicals that shoul...

Wastewater is a point source for many contaminants of emerging concern (CECs) and surface waters receiving their discharge often serve as source water for downstream drinking water treatment plants (DWTPs). Non-targeted chemical analysis methods and suspect screening tools have b...

In 2017, WE&RF published the guidance document “Risk-Based Framework for the Development of Public Health Guidance for Decentralized Non-Potable Water Systems” recommending pathogen log-reduction targets (LRTs) for the treatment of alternative water sources (graywater, combined w...

This presentation highlight EPA&rsquo;s work that impacts sustainable design. In a separate presentation, John Katz, Pollution Prevention Coordinator with EPA&nbsp;Region 9 in San Francisco, will provide a brief overview of EPA and the laws and regulations related to products, an...

Recently, multiple states have explored treatment and monitoring procedures for water reuse. Advisory panels from states such as California and Texas have recommended using effects-based bioassays to screen for emerging contaminants. Due to the presence of polycyclic aromatic hyd...

Defining the treatment necessary for safe nonpotable reuse of on-site collected wastewaters was identified by stakeholders as a key roadblock for greater adoption. Subsequent risk-based modeling research developed treatment guidance which has been translated into regulation in mu...

Sustainability and system thinking is important in environmental education, environmental management and future design.

&nbsp; Recently, multiple states have explored treatment and monitoring procedures for water reuse. Advisory panels from states such as California and Texas have recommended using effects-based bioassays to screen for emerging contaminants. Due to the presence of polycyclic aroma...

Summarize recent results from ORD research on onsite nonpotable water reuse systems, emphasizing our work with quantitative microbial risk assessment and life cycle analysis. 

The need for defining treatment guidance for safe onsite non-potable water reuse was identified as a key roadblock to adoption by a diverse group of public health regulators and utilities who came together to form the National Blue Ribbon Commission (NBRC) for Onsite Non-potable ...

Risk-based management of onsite non-potable water systems relies on pathogen log-reduction targets (LRTs) derived using best-available scientific information. Here, we present new LRTs for California and discuss implications in comparison to previous recommendations. We also high...

Recently, multiple states have explored treatment and monitoring procedures for water reuse. Advisory panels from states such as California and Texas have recommended using effects-based bioassays to screen for emerging contaminants. Due to the presence of polycyclic aromatic hyd...

The annual risks of colonization, skin infection, blood stream infection (bsi), and disease burden from exposures to antibiotic resistant and susceptible Staphylococcus aureus (S. aureus) were estimated using quantitative microbial risk assessment. We estimated the probability of...

Virtual presententation to regional (San Diego) Water Tech Aliance providing high-level overview of risk-based approaches for stromwater capture and use.

The overall purpose of the Pilot Study is to develop a national-scale, quantitative assessment of AMR within surface water. The four main objectives as developed from initial meetings of the National Antimicrobial Resistance Monitoring System Environmental Working Group (NARMS EW...

Antimicrobial resistance (AMR) has been identified as one of the top medical issues worldwide, leading many countries to place greater emphasis on combating resistant bacteria through a multipronged, coordinated approach.&nbsp; A consensus has emerged among the greater public hea...

Greywater, the wastewater from sinks, showers, and laundry, is an understudied environment for bacterial communities. Most greywater studies focus on quantifying pathogens, often via proxies like Fecal Indicator Bacteria. More recently, sequencing-based studies have revealed dist...

Facing changes in water demands and population size, particularly in the water scarce regions in the United States, the reuse of treated municipal wastewater has become a viable potential to relieve the ever-increasing demands of providing water for (non-) potable use. The object...

The National Blue Ribbon Commissions is a coalition of public health agencies and water and wastewater utilities that advances best management practices to support the use of onsite non-potable water systems within individual buildings or at the local scale.&nbsp; This presentati...

The U.S. EPA&rsquo;s Non-Potable Environmental and Economic Water Reuse (NEWR) Calculator is a simple to use web-based tool for screening-level assessments of source water options for any urban building location across the Unites States that is considering onsite non-potable reus...

The mission of the Center for Public Health and Environmental Assessment (CPHEA) is to provide the science needed to understand the complex interrelationship between people and nature in support of assessments and policy to protect human health and ecological integrity.&nbsp; CPH...

EPA is announcing the availability of this final report prepared by the Safe and Sustainable Water Resources (SSWR) Research Program, located within the Office of Research and Development, with support from Eastern Research Group (ERG). This report is a summary and synthesis of s...
