The copper content of drinking water generally falls below 0.03 parts per
million, but copper levels as high as 1.0 part per million will give water a bitter
taste. Waters testing as high as 1.0 part per million copper have probably been
treated with a copper compound, like those used in the control of algae, or
have become contaminated from untreated industrial wastes. The addition of
copper sulfate to lakes causes an increase in the copper content of the
sediments. Acid waters and those high in free carbon dioxide may cause the
corrosion or “eating away” of copper, brass and bronze pipes and fittings. This
corrosion results in the addition of copper to the water supply.
APPLICATION: Drinking, surface, and saline waters; domestic and industrial
wastes.
RANGE: 0.0–4.0 ppm Copper
METHOD: Cupric ions form a purple complex with bicinchoninic acid
around pH 6–7, in proportion to the concentration of
copper in the sample.
