- Iron was found at levels that exceed the secondary MCL of 300μg/L. The MCL was set to protect you against unpleasant aesthetic effects (e.g. color, taste and odor) and staining of plumbing fixtures (e.g. tubs and sinks) and clothing while washing. The high level is due to leaching from natural deposits from one well.
