A method and apparatus for detecting contaminants in an aqueous flow. The method involves providing a conduit having at least one ion collection portion, disposing the aqueous flow through the conduit, attracting target ions to the ion collection portion such that they are bonded to the ion collection portion, and detecting a contaminant, or contaminants, based upon a predetermined property of the plurality of target ions bonded to the ion collection portion. In the preferred embodiment of the method, the predetermined property is a conductivity of the target ions, and the detecting step involves measuring a change in conductivity of the collection portion as ions are bonded and comparing that conductivity to a predetermined conductivity. The apparatus includes a conduit into which an ion collection portion is disposed, a sensor that senses ions collected on the ion collection portion and sends a signal corresponding to a value of a predetermined property of the ions, and a microprocessor in communication with the sensor and programmed to process the signal and determine the presence of the at least one contaminant based upon the processed signal.
