Abstract |
The coliform group of indicator organisms has a relatively low resistance to chlorine when compared to pathogens such as enteric viruses and protozoan cysts. Consequently, an effort has been initiated to find a new chlorine resistant bioindicator of wastewater chlorination efficiency. A yeast and two different acid-fast bacilli were found to be resistant to chlorination in the range considered necessary for the inactivation of pathogens, including viruses. One acid-fast bacillus survived 2.0 mg/l free chlorine for 67 min while the other survived 1.0 mg/l free chlorine for 15 min. The yeast resisted 1.0 mg/l free chlorine for 20 min. In comparison, a pure culture of E. coli failed to survive five min contact with 0.03 mg/l free chlorine. The chlorine resistance and other characteristics of the yeasts and acid-fast bacilli under study suggest that they show promise as bioindicators for wastewater chlorination for the more chlorine resistant pathogens. |
