Chlorine is the most common water disinfectant. Once in the water, it presents as free chlorine and total chlorine. Free chlorine is the chlorine left in the water to tackle bacteria. As the process of disinfection takes place, the levels of free chlorine will reduce. Total chlorine is the measurement of free and used chlorine in the water.

| Method | Adaptation of USEPA method 330.5. The reaction between free chlorine and the DPD reagent will cause a pink tint in the sample. | EPA approved DPD method Standard Method 4500-Cl G. |
| Interference may be caused by | Bromine, Iodine, Ozone, Oxidised forms of Chromium and Manganese. In case of water with hardness greater than 500 mg/L CaCO3, shake the sample for approximately 2 minutes after adding the powder reagent. If the water used for this procedure has an alkalinity value greater than 250 mg/L CaCO3 or acidity value greater than 150 mg/L CaCO3, the colour of the sample may develop only partially, or may rapidly fade. To resolve this, neutralise the sample with diluted HCl or NaOH. PLEASE NOTE: In some cases, samples may contain other parameters which may interfere with results |
