Musty Taste & Odor
Occasionally Columbus water has an earthy, musty or fishy taste and odor.
These seasonal phenomena can be caused by the bi-annual turnover of our city reservoirs, or with the presence of varied algal blooms (photo) in the reservoirs or rivers.
It is important to note this taste and odor poses no health concern but one of aesthetic quality. Advanced treatment techniques involving powder activated carbon and remote real-time sensors are being used to help mitigate this problem.
