The water quality success of the direct potable reuse project in Big Spring is measured by a nearly three-year long study that has spanned the majority of the facility's operating history to date. Study sampling for a wide range of CECs indicates that concentrations in the influent to the advanced treatment train are already below health-based benchmarks defined by a national panel of experts, and concentrations in the product water, where detected, are even lower. This article is focused on the results of pathogen sampling and the implications of those results. The pathogen sampling conducted for this project provides concrete proof that while well-treated effluent is unquestionably a valuable water resource, and can be further treated to become an important part of a water supply, it is not a suitable source of raw water for conventional drinking water without additional treatment.
