PurTest Coliform Bacteria in Water Test Kit
The Model TC-5 is an easy-to-use, disposable 5 tube method to indicate the presence of total coliform bacteria in a drinking water supply. The sample is introduced into the test vials containing the special coliform indicating tablets and stored at room temperature for a predetermined time period. After the required storage period, the vials are examined to determine the presence of coliform bacteria. The test method and results closely parallel the standard Total Coliform Muliple-Tube Presumptive Test (MPN) as outlined in Standard Methods for the Examination of Water and Wastewater.
The tablets in the Model TC-5 contain nutrients to support the growth of coliform bacteria, a gelling substance, and pH indicator. If coliform organisms are in the sample, gas will be generated as a result of the bacteria metabolizing the nutrients in the tablets. This gas will be trapped in the gelling substance and cause the gel to rise in the tube. The pH indicator may change color from red to yellow as further evidence of coliform bacteria activity.
Each kit contains:
- 5 glass tubes, marked at the 10ml level and containing one Coliform Test Tablet each
- A sterile water sampling bag containing a dechlorinating tablet (for chlorine removal)
Fecal coliform bacteria infection in drinking water can lead to diseases such as typhoid fever and cholera, though these diseases are rare in the United States. Fecal coliform bacteria contamination can also lead to infectious hepatitis and dysentery, which are more common. Some experts believe that exposure to high levels of bacteria in drinking water can also make infants more susceptible to the toxic effects of nitrates in drinking water. Symptoms associated with bacterial infection include digestive problems, fever, nausea, diarrhea and cramps.
Reading the Results: After 48 hours, check for any color change inside the vial without opening it.
