Why Should You Test for E. Coli and Coliform Presence in Water?

E. coli and coliform bacteria presence in water indicates potential fecal contamination of the water source. These bacteria can lead to serious illness in humans. Infection symptoms include bloody diarrhea, stomach cramps, vomiting and occasionally, fever.

Coliform bacteria can also cause pneumonia, other respiratory illnesses and urinary tract infections. In case E. coli or other coliform bacteria are detected, the water should not be consumed. Further investigation and testing of the entire system should be initiated to confirm the results. AquaVial E. Coli and coliform is a quick visual indicator of water quality at home or during your travels, at the cottage, on your boat and RV. The kit is a great addition to your pool and hot tub water testing routine.

How is AquaVial E. coli and coliform different?

AquaVial E. coli and coliform test kit uses the most recent advances in biotechnology research to detect the presence of coliform bacteria with a simple to read color change. The nutrients used in our formulation are specifically designed to enhance the sensitivity to fecal coliform bacteria. This formulation reduces the risk for false positive results .

The color change is produced by a dye that is changing its color from yellow to purple in presence of an enzyme (glucosidase). This enzyme is produced by all coliform bacteria.

Compared with other tests on the market, our test has a simpler testing method. Just add 4 ml of water with the pipette provided and wait. The results can be read within 24 hours at 35- 40 degrees Celsius. If the test is kept at lower temperature, confirm there is no color change after 48 hours.

Frequently Asked Questions

Q: How many test can be done with one kit?

A: Each kit contains  test vials and disposable pipettes and caps for performing 2 tests.

Q: What happens if I add less or too much water?

A: The test is designed as a limit test,as a result is less sensitive to the exact amount of water used in the test. If at least one coliform bacteria is present the test will change color withing 48 hours

Q: What does it means if the vial remains yellow in the first 48 hours but changes color a couple of days later?

A: The reagent in the test vial detect presence of an enzyme produced by coliform bacteria. However the enzyme can be sometime present at very low concentrations from other sources of from dead bacteria. This can cause the solution sometimes to change color after a longer time ( after 4-5 days or even longer). However, if the vial did not change color within the first 48 hours there is no viable (live) fecal coliform bacteria in your water.
