[Study on application of hazard analysis and critical control point in rural water supply system].

ABSTRACT

OBJECTIVE: To study the feasibility and effect of the HACCP application in rural water supply systems. The Tucheng water supply system (TWSS) in Hebei Province was selected as study field. METHODS: The hazard analysis and evaluation were developed according to WHO/FAO "HACCP System and Guidelines for its Application" and WHO "Guidelines for drinking water quality". RESULTS: The CCP was found and the control measures were established based on hazard analysis. The present study showed that the CCP could be found in all steps of the water supply system. After the HACCP application in TWSS, no distinct improvement of water quality was observed, but the occupational technical knowledge score of the staff was improved from 75.2 to 86.6. CONCLUSION: The results indicated that as a risk management tool, application of HACCP in rural water supply system is feasible.
