A fix for fixtures: Addressing lead contamination in west african drinking water

Abstract

Lead in drinking water is an issue of global concern.1 New research published in Environmental Health Perspectives documents the problem in previously unexamined areas of rural West Africa,1 further indicating the wide reach of this harmful contaminant. Lead rarely occurs naturally in drinking water; most often it leaches from lead-bearing plumbing components, such as pipes, solder, or brass fittings. Characteristics of the piped water, such as low pH level or low phosphate content, can cause these components to corrode over time, allowing the metal to contaminate drinking water.2.
