The WaterCheck™ test kit is a screen tool to detect sewage contamination in water.  The test detects the presence or absense of Coliform and E.Coli Bacteria, indicative of fecal pollution.  WaterCheck™ is sensitive enough to meet national drinking water standards of a single colony forming unit (cfu) per 100 ml of water.  It is simple to perform, easy to interpret and requires minimal preparation.


WaterCheck™ is based on the unique ability of coliform bacteria to utilize special nutrients and re-agents to form a distinctive blue-green color.  The presence or absence of a single cfu in coliform/E.Coli in water is an international standard measure to determine safe drinking water.  If the water sample is contaminated with just a single cfu, a visible blue-green color will develop.


WaterCheck™ is a simple do it yourself at home, test.  The kit is provided as a sterilized plastic bag, which is ready to use.  Water sample collection, mixing, incubation, and observation are all done in the same bag.  Detailed instructions are included on the inside of the package.


Wells or privately treated water systems may be susceptible to contamination by human or animal waste.  To ensure drinking water safety health authorities suggest home owners test their water at least twice a year.  Regular use of the WaterCheck™ test will help protect against the dangers of waterborne pathogenic micro-organisms by providing a warning of possible fecal contamination.
