8<br />

A small amount <strong>of</strong> chlorine, bleach, or chloramine is added (or some other disinfection<br />

method is used) to kill any bacteria or microorganisms that may be in the water. Once<br />

disinfecting agents have been added, the water is held in storage to allow disinfection to<br />

take place. The water then flows through pipes, to homes and businesses in the<br />

community.<br />

After chlorine is added to the water, some free residual chlorine remains. This provides<br />

continued antimicrobial action. A significant drop in free residual chlorine indicates either<br />

a lack <strong>of</strong> disinfectant input or a high chlorine demand – suggesting the presence <strong>of</strong><br />

nitrates or other material in the water.<br />
