Expanding water reuse--the use of treated wastewater for beneficial purposes including irrigation, industrial uses, and drinking water augmentation--could significantly increase the nation's total available water resources. Water Reuse presents a portfolio of treatment options available to mitigate water quality issues in reclaimed water along with new analysis suggesting that the risk of exposure to certain microbial and chemical contaminants from drinking reclaimed water does not appear to be any higher than the risk experienced in at least some current drinking water treatment systems, and may be orders of magnitude lower. This report recommends adjustments to the federal regulatory framework that could enhance public health protection for both planned and unplanned (or de facto) reuse and increase public confidence in water reuse.
Learn more with Understanding Water Reuse, a booklet that provides an overview of the options and outlook for water reuse in the United States, discusses water treatment technologies and potential uses of reclaimed water, and explains analyses that compare the risks of drinking reclaimed water to those of drinking water from traditional sources.
