  • [Objective] To evaluate the quality of water supplied by small central rural water facility in Jining prefecture with solitary-factor and comprehensive index.

    [Methods] A total of 109 small central rural water supply facilities in 6 counties were selected;and with water samples in rate of 20 : 1 from each county, including 93 deep and 16 shallow wells were taken. The samples were collected from both in factory and at peripheral end in dry(April-May 2008)and wet season(July-August 2008). The water quality was evaluated with both solitary-factor and comprehensive index methods(modified Nemerow index).

    [Results] The indicators exceeded national standard were noticed in total hardness, sulfate, nitrate, or numbers of bacteria and total coliforms in solitary-factor evaluation. Jiaxiang was the only 0.50(classⅡ)and the others counties were all below 0.45(classⅠ)in the evaluation with comprehensive indexes.

    [Conclusion] The modified Nemerow index combined with solitary-factor evaluation methods could objectively reflect the quality of water supplied by small central rural facilities in Jining prefecture.
