The WaterCheck™ test kit determines the presence or absence of coliforms and E.coli bacteria, indicative of fecal pollution. It is sensitive enough to detect even 1 CFU/100mL of water.
It is very easy to use – Water sample collection, mixing, incubation, and observation are all done in the same bag. Just add water to the test pouch that has a special reagent and store for about 24 hours. If the water changes color to blue/green, coliform are detected.
WaterCheck™ is ideal for use in cottages, recreational homes and residences that are on untreated water supply.
1. Run tap water for 2 to 3 minutes. Tear perforated strip and open bag by pulling white tabs. Fill bag with water, up to the fill line (Approximately 100 ml). Do not touch inside of bag.
2. Remove excess air and roll bag four or five times around wire strip. Bend wires to seal.
3. Remove divider clip. Mix powder into water until completely dissolved (10 to 30 seconds).
