Abstract: Systems and methods for monitoring biofilm growth are provided. A method comprises supporting at least one coupon in a water reservoir, wherein the water reservoir feeds water into a tower interior, removing the at least one coupon from the water reservoir, and measuring a level of biofilm growth on the at least one coupon. The level of biofilm growth on the at least one coupon is predictive of a level of biofilm growth within the tower interior. Providing an indicator of predictive biofilm growth may allow measures to be taken to prevent biofilm growth in other sectors or areas of the tower.
