Levels of molybdenum in drinking-water do not usually exceed 10 µg/l (Greathouse Osborne, 1980). However, in areas near molybdenum mining operations, the molybdenum concentration in finished water was reported to be as high as 200 µg/l. Tapwater concentrations as high as 580 µg/l have been reported in Colorado (Chappell, 1973).
