Can my home water heater also be a source of ldb contamination?

Sometimes: If the water heater heats water to less than 140 degrees, ldb could grow. It is more common to have the bacteria grow in a humidifier or fountain, or in an industrial cooling tower.

No.: Not typically. Small water systems and those at temps above 120 f are not a significant source of contamination.
