Drinking Water Quality
Manganese, a harmless chemical dissolves in water, it is colorless. When the manganese combines with air as you take water from your faucet, the manganese turns black. Generally, flushing your cold water lines for a few minutes should clear this up (as with almost any of the water quality conditions), but if it persists, please contact the Utilities Operations Division so that it can be investigated further.
