Forsyth County Water and Sewer Department is aware that some residents have reported that their water has an unusual taste and odor. Testing of the raw water from Lake Lanier has confirmed that levels of Methylisoborneol (MIB) and Geosmin are higher than have been seen in past years. 

These two compounds are not harmful. However, they can cause an earthy, musty taste and odor in water. While some people may notice this, many others will not notice it. Unfortunately, this taste and odor are not easily removed by traditional treatment techniques.  

This earthy, musty taste and odor can be caused by what is referred to as the “turn over,” or inversion, of Lake Lanier, as well as other land conditions which can release these naturally occurring compounds.

We are working to modify our treatment processes to reduce the levels of MIB and Geosmin in the finished water. We are already seeing the reductions from our process changes, but it may take a few days for it to improve at all locations.

Forsyth County Water and Sewer Department appreciates residents’ patience while we work through this situation. Please be assured that your water is safe to use and drink, even if it may smell and taste different than normal.
