Proposals due November 5, 2019

The 2016 Expert Panel report (Evaluation of the Feasibility of Developing Uniform Water Recycling Criteria for Direct Potable Reuse) offered three specific recommendations concerning antibiotic resistance in recycled water: 1) need to develop risk models, 2) need for standardized ARB/ARG monitoring methods, and 3) need to assess the efficacy of various advanced water treatment technologies for ARB/ARG removal. Using the results of this report, the 2018 Science Advisory Panel on Constituents of Emerging Concern in Recycled Water identified the need to develop a consensus on analytical methods to detect ARB/ARGs before monitoring for ARBs/ARGs could be recommended.

Recent advances in molecular methods (including metagenomics and qPCR) have the potential to detect and characterize ARB/ARGs in a culture-independent, systematic manner. Identifying a Standard Operating Procedure (SOP) with QA/QC measures will provide the industry with a better understanding of the occurrence of ARB/ARGs in surface water, wastewater, and recycled water. This project addresses the need for standardized monitoring methods, which is the first step to work towards the other recommendations. Well-established methods will make it possible to reliably measure the removal of ARB/ARGs through the treatment process, and the use of these methods in future studies will provide an understanding of potential risk.
