This is a remarkable divergence in threshold of detection. Unfortunately, removal of the taste and odor constituents of these compounds is difficult at best. The use of various forms of carbon is widely used to adsorb the objectionable taste and odor. This water treatment technique is costly and marginally effective. The Village, the Northwest Water Commission, and the City of Evanston are currently evaluating enhanced water treatment techniques that have the potential to eliminate or greatly reduce this problem.
Breaks normally occur in older cast-iron watermains.
