The Water Research Foundation has issued an RFP for its Assessing the Microbial Risks and Potential Impacts from Stormwater Collection and Uses to Establish Appropriate Best Management Practices program.
Pathogens are one of the common pollutants in stormwater runoff. The fate and transport of pathogens in stormwater flows can vary widely, resulting in very different pathogen concentrations. Even in stormwater collection systems that are separated from municipal sewers, sewage ingress occurs within urban areas through various pathways, including cross-connections, leaking sewers, and rain-induced overflows to stormwater collection systems. Therefore, there is a need to expand the risk-based framework developed in the report Risk-Based Framework for the Development of Public Health Guidance for Decentralized Non-Potable Water Systems (SIWM10C15) and more broadly assess the enteric and non-enteric microbial risks and potential impacts from stormwater collection and uses to help establish risk-based best management practices.
Through the RFP, grants of up to $75,000 will be awarded in support of efforts to assess the microbial risks and potential impacts from stormwater collection and help establish appropriate best management practices for stormwater harvesting/reuse and other stormwater control measures; better understand the severity of stormwater microbial contamination from fecal indicator bacteria and other pathogens, types, and concentration of microbes, as well as growth over time in a variety of common stormwater scenarios; use the Risk-Based Framework for the Development of Public Health Guidance for Decentralized Non-Potable Water Systems (SIWM10C15) to develop a roadmap that can guide utilities/stormwater managers in assessing site-specific microbial risks associated with stormwater collected for intended uses; and synthesize key methods and strategies in assessing baseflow and rain/snowmelt event microbial indicators to aid risk management based on evolving log-reduction pathogen targets. Projects will formulate a mitigation strategy for exposure risks related to pathogens from stormwater, as well as for stormwater harvesting applications to enhance the protection of public health.
Domestic and international entities, including educational institutions, research organizations, governmental agencies, and consultants or other for-profit entities, are eligible to apply for a grant.
