42、water, mu-nicipal (treated) water, or a low mineral content well water (seeAppendix X1, Table X1.1). This procedure will minimize theformation of hard water scale and avoid the introduction ofmineral components, such as chlorides and sulfates, which canincrease the corrosion rate of aluminum and iro
