Abstract
A contaminant measurement system is provided. The system is operable to detect and measure a concentration level of a preselected contaminant, e.g., lead, in water disposed within a chamber of the system. The system includes a detection agent that is operable to interact with the preselected contaminant in the water. The detection agent can be a plurality of polymeric beads or a membrane, for example. The system has a sensing circuit that includes a pair of electrodes spaced from one another and both at least partially disposed in the water. A controller is communicatively coupled with the sensing circuit and is configured to receive one or more electric signals from the sensing circuit. The controller determines a parameter indicative of the concentration level of the preselected contaminant based on the one or more electrical signals. The controller then determines and outputs the concentration level of the preselected contaminant.
