Analysis on Quality of Drinking Water from Rural Drinking Water Safety Project in Zhongshan County in 2008—2012

Objectives  To learn the quality of water from the rural drinking water safety project (RDWSP) in Zhongshan County, thus to provide scientific basis for strengthening the construction of RDWSP.

Methods Analyzing the data monitored in 2008-2012 for the RDWSP.

Results A total of 500 water samples were monitored in five years, with a pass rate of 19.20%.The pass rate in different years showed an increasing trend.The pass rate for sensory and general chemical index was 81.0%, for toxicological index was 100.0%, for microbiological index was 19.4%.The quality of water between dry and wet season was not significantly different. The quality of underground water was significantly higher than that of surface water.

Conclusions Microbial contamination is the main factor affecting the water quality in RDWSP in Zhongshan County.
