THE INACTIVATION OF PURIFIED TYPE 3 ADENOVIRUS IN WATER BY CHLORINE1

Abstract

The amounts of free chlorine necessary to inactivate approximately 99.8% of purified type 3 adenovirus in water were determined and are approximately the same as required to destroy Escherlchia coli or Salmonella typhosa. Inactivation times were dependent on chlorine concentration, temperature and hydrogen ion concentration. These results indicate that transmission of this virus through water in a well-chlorinated pool seems unlikely, and that water containing no demonstrable members of the coli-form group is probably free of type 3 adenovirus.
