Abstract: The present disclosure relates to a method for determining the necessity of an action and/or a success of an action involving water, especially drinking water, process water or waste water, including steps as follows: providing a retentate of a water filter present in a water conveying line, analyzing the retentate regarding at least one property and/or its chemical composition, and determining the necessity or success of the action and, in given cases, deriving the action from the analysis. Furthermore, the present disclosure relates to a system including a means for providing the retentate of a water filter in a water conveying line and a measuring/analytical means for performing the analysis.
