Enhanced Pathogen Log Reduction Value for Underground Retention and Transport Grant

The Water Research Foundation (WRF) is offering a grant opportunity titled “Enhanced Pathogen Log Reduction Value for Underground Retention and Transport” (Project 5407). This grant aims to support research on pathogen log reduction values (LRVs) in managed aquifer recharge (MAR) and groundwater replenishment reuse projects (GRRP). The deadline for applications is 3 November 2026, at 3:00 pm Mountain Time (GMT-07:00). This grant seeks to evaluate the applicability of WRF project 4957’s site-specific pathogen log reduction value assessment workflow. The research will focus on MAR and GRRP sites, exploring different types of transport mechanisms such as saturated flow and unsaturated vadose zone transport. The goal is to identify practical considerations for implementation and develop guidance for utilities and regulators to validate pathogen LRV credits. The grant offers financial support of up to $250,000. This funding is intended to cover research activities, including field data collection, tracer studies, surrogate indicators, monitoring approaches, and modeling tools. The results will be compared to current regulatory default credit assumptions, providing valuable insights for utilities and regulators. Eligible applicants are organizations with an interest in participating in this research project. The opportunity is specifically designed for entities capable of conducting comprehensive studies on pathogen log reduction values in underground retention and transport systems. This grant is crucial for advancing the understanding of pathogen reduction in water reuse projects. By providing financial support for research, it aims to enhance the safety and reliability of water management practices, benefiting both utilities and regulators in their efforts to ensure public health and environmental protection. For further instructions on submitting proposals, refer to the provided guidelines or instructional video on the official website. Eligible organizations are encouraged to review the official guidelines and prepare their proposals in accordance with the specified requirements.
