42 U.S.C. § 300j–19d — Review of technologies

(a) Review. After consulting with relevant federal, state, and local agencies, the EPA must review — or contract out a review of — existing and possible future methods, equipment, and technologies (including their cost, availability, and how well they work) that: protect the physical safety of community water systems; prevent, detect, and respond to any contaminant covered by a national drinking water rule, in both community water systems and their source water; allow use of alternative drinking water supplies from nontraditional sources; and help with assessing and protecting source water. (b) Inclusions. This review must cover technologies used for corrosion protection, metering, leak detection, or preventing water loss; smart systems (hardware, software, or other tech) that help with those same tasks; point-of-use or point-of-entry devices; physical or electronic systems that monitor contaminants in real time; and technologies — including physical separation and chemical or biological treatment — that allow use of nontraditional drinking water sources. (c) Availability. The EPA must make the review's results public. (d) Authorization of appropriations. Congress could spend $10,000,000 on this section for fiscal year 2019, available until spent.
