Abstract: The number, location and pollutant discharge amount of the sewage outlets  were investigated at 9 conservation areas of drinking water  in Xiangxi Autonomous Prefecture, and the data of 24 monitored indices for water quality at these regions were analysed and assessed with single pollution index. The results showed that there was a profusion of drinking water sources in these regions, and the water quality was also good in general. However, the water quality  decreased obviously due to a large pollutant discharge.

Key words: conservation areas of drinking water, water quality situation, assessment, Xiangxi Autonomous Prefecture
