A water quality sampling system and method in which compact water impurity detector and monitoring units intended for domestic use are installed in a residential environment while detected values are electronically transmitted to a Central Monitoring Station (CMS), where customers can register and pay over the Internet. Using the impurity detector units, a portion of an incoming water stream is passed to an analyzer for detection of chlorine and various contaminants. The detector analyzes related data for determining the condition and extent of impurity in the water elements. This data is transmitted from a compact control box, known as the wall unit, that translates the data for output to the CMS, located in another geographic locale, via a common data acquisition network. This network can be the Internet or a cellular and/or satellite connection. Upon detection of contaminants above a threshold level, the monitoring device will make a sound through a wall unit located in the vicinity, to warn the average household tap water user of such unsatisfactory condition of his/her water elements, as the conditional values are sent using EDI onto the network, and then onward to the CMS website. |
