This sensory test is a powerful tool for process control and can be used for routine testing and early warning. If a potential problem is detected or jar testing is needed to determine treatment changes, the reliable, yet more complex tests, such as TON and FPA, should be used. If a geosmin episode occurs, use an FPA panel to monitor the odor intensity of the earthy odor. It is vital to focus the limited energies of operators and process scientists on the changes in taste and odor quality. Once changes are flagged – hopefully taking only a small percentage of the overall time spent in testing water–then more detailed tests or actions can be pursued.
