Abstract
A system and method are directed to detecting the presence of heavy metals in a flowing fluid, such as a drinking water supply. The system includes a first chamber for receiving a filtered portion of the fluid and a second chamber for receiving an unfiltered portion of the fluid. A test device measures electrical properties of the filtered fluid in the first chamber and the unfiltered fluid in the second chamber, such as an electric potential difference, and a controller can use the measured electrical properties to detect the presence or quantity of one or more heavy metals within the fluid, such as lead, cadmium, zinc, nickel, and/or copper.
