Qualified rates were 18.87 %, 19.85 %, 25.00 %, and 26.92 % during 2008-2011 respectively. The qualified rates of finished water were 26.79% and 29.70% in dry season and the wet period respectively. The pass rates of the peripheral water were 22.39% and 15.17% in dry season and the wet period respectively. Over 88% of qualified rates were general sense and chemical indicators and toxicological indicators （But the rate of nitrate nitrogen was 58.74 %）. The lower qualified rates detected indicators mainly total coliform （76.22 %） and the total count of colonies （42.48%）. [Conclusion]Sanitary quality of drinking water in rural areas in Penglai is poor.
