INTRODUCTION
Chlorine is added to water to kill bacteria and other disease-producing organisms,
control algae, and remove undesirable odors and colors. Chlorine added to water
quickly forms hypochlorous acid, HClO, also known as Free Available Chlorine, the
active ingredient responsible for chlorine’s sanitizing capabilities. Free Available
Chlorine combines with impurities in the water to form chloramines and other organic
nitrogen compounds. In combined form, its sanitizing capability diminishes, and
higher levels of chlorine are necessary to achieve effective sanitation.
Therefore, it is essential to chlorinate to the point of establishing a Free Available
Chlorine Residual, and then to maintain that residual at a recommended level. The
LaMotte DPD method distinguishes levels of Free Available Chlorine, Combined
Chlorine, and Total Residual Chlorine, using a single test sample.
