10. TESTING DRINKING WATER
WITH WATABLUE
® (DETERMINATION
OF RESIDUAL CHLORINE)
It is important to test the concentration of residual chlorine to protect
the treated water against a possible recontamination and to avoid a
strong taste of chlorine.
The WataBlue ® reagent test determines the concentration of residual
chlorine in the treated water. Please refer to the WataBlue ® user’s
manual.

It is absolutely necessary to test for residual chlorine using the WataBlue ® test 30
minutes after chlorinating your drinking water. Only this test result will guarantee
protection against waterborne diseases.

1 2 3 4
1
Using a small syringe, collect 5 mL of your sodium hypochlorite solution.
2
Add 5 mL of sodium hypochlorite per 20L of plain water.
3
Shake vigorously (for chlorinating a water tank, add the sodium hypochlorite to the
half-full tank, then add the rest of the water).
4 Wait 30 minutes for the sodium hypochlorite to act to inactivate the microbes.
5 Test for the presence of residual chlorine using the WataBlue ® reagent.
