Drinking Water Color, Taste, and/or Odor Concerns

If you have discolored water, you should open a cold water faucet and let the water run for up to five minutes. If the color does not clear up, please report the issue below.

For additional information on discolored water or taste and odor, please review answers to Customer Service Frequently Asked Questions Nos. 14-17 by clicking here.

September 2018 Taste and Odor Complaints: If your water has a musty or earthy smell and taste, the water is safe to drink.  The hot and dry weather has caused an increase of geosmin and MIB (2-Methyl-iso-Borneol) in Allatoona Lake. Geosmin and MIB are naturally occurring compounds found in surface water. They affect only taste and odor, not the safety of the water.  Our wholesale water supplier has made an adjustment to their treatment process to reduce the impact. Unfortunately, the issue will probably not resolve completely until we receive consistent rain.
