Protecting Water Supply Springschlorine odor is detected at each one. Close the fauce ts to allow the chlorine solution to remain inthe system for at least 12 hours.4. Open all valves and faucets to allow fresh spring water to flow through the system until nochlorine odor or taste can be detected.5. Test the spring water for bacterial contamination 24 hours after chlorine has been removed fromthe spring and household system.Continuous chlorination is necessary if bacterial contamination continues after repeated shockchlorinations. In this system, equipment is used to feed chorine continuously in sufficient amounts to killbacteria. Chlorine must be in contact with water at least 1 to 5 minutes to kill all bacteria. At the end ofthis time, a chlorine residual of about 3 to 5 ppm should remain to indicate that the disinfection iscomplete. Typical chlorine feed rates are about 1 cup of 5 percent laundry bleach per 300 gallons ofwater. This rate depends on water temperature, pH, and pumping rate. Use an inexpensive chlorineresidual kit to determine if the feed rate should be increase of decreased to obtain the proper chlorineresidual.Distributed in furtherance of the Acts of Congress of May 8 and June 30, 1914.
