Evaluating endogenous viral targets as potential treatment monitoring surrogates for onsite non-potable water reuse.

ABSTRACT: Onsite non-potable water reuse systems (ONWS) are decentralized systems that treat and repurpose locally collected waters (e.g. greywater or combined wastewater) for uses such as irrigation and flushing toilets. To ensure that treatment is meeting risk benchmarks, it is necessary to monitor the efficacy of pathogen removal. However, accurate assessment of pathogen reduction is hampered by their sporadic and low occurrence rates in source waters and concentrations in treated water that are generally below measurement detection limits. An alternative metric for evaluation of onsite water treatment is log reduction of a more abundant organism that can serve as a surrogate for the pathogen removal. Viruses endogenous to the decentralized system could serve as monitoring surrogates to ve
