Does the path to clean, safe water lead through a brewery?

Andy Wales, head of sustainable development at global brewer SABMiller, maintains it can happen.  The maker of Miller beer — and 20 other brands, from Aguila in Colombia to Zolotaya Bochka Klassicheskoye in Russia — likes the environmental angle, but the main impetus is to ensure production of their products in what is a highly variable business from location to location.
