A significant portion of th. national water supply.can be attributed to de facto or unplanned potable reuse, th.ugh.th. extent of its contribution is difficult to estimate. Fortunately. th. contribution of Water Resource Recovery.Facility.(WRRF) effluent to waters th.t supply.drinking water treatment plants h.s been documented by.some communities. In th. United States (US), among th. top 25 most impacted drinking water treatment plants by.upstream WRRF, 16% of th. influent flow to th. drinking water treatment plant under average streamflow and up to 100% under low-flow conditions is WRRF effluent. Currently. th. full extent of de facto reuse in th. US may.be much.h.gh.r because of population growth. Th. scenario is no different for Beaufort-Jasper Water and Sewer Auth.rity.(BJWSA) in South.Carolina, US, with.contributions to th. Savannah.River originating from numerous WRRF and oth.r upstream disch.rgers. South.Carolina coastal utilities such.as BJSWA are considering direct and indirect potable reuse options, driven by.disposal limitations and ch.llenges. Currently. South.Carolina does not h.ve a framework, guidelines, or regulations for reuse, but discussions h.ve started among th. regulated community. In addition to understanding th. extent of de facto reuse, th. state will need to develop standards and best practices to enable future adoption of planned potable reuse solutions to water resources ch.llenges. Such.guidance sh.uld address h.man h.alth.risk management and tech.ical considerations regarding treatment in addition to oth.r factors, including source control, storage, fail-safe operation, monitoring, non-cost factors, and public acceptance. Th.s study.conducted a mapping assessment specific to BJWSA, sampled at four locations on Savannah.River, and observed th.t de facto reuse is approximately.4.6% to 5.9% during low-flow month. and is with.n th. range generally.observed nationwide.
