Abstract:
Objective To know drinking water quality in the rural areas of Jiangxi province and to provide a scientific basis for making the policy of water improvement.Methods In 2007,twenty-two counties in Jiangxi Province were chosen to investigate the drinking water quality in the rural areas(the types of water source,the ways of water supply,drinking water treatments and population).There were 10-11 monitoring sites in each county.In the dry season(March to May) and wet season(August to October),the water samples were collected,conserved,analyzed and evaluated.Results Of 8 726 568 rural population,16.76% used central water supply taking river water as the water source,83.24%used separate water supply using the shallow and deep layer groundwater as the water source.88.52%of the people consumed the water which was not treated.In wet season and dry season,221 water samples were collected respectively,surface water and groundwater accounted for 21.27%and 78.73% respectively,43.89%and 51.58%of the water samples reached the drinking water standard respectively.In wet season and dry season,the eligible rate of water using surface water as the water source was 63.83%and 59.57%respectively,and it was 38.51% and 49.43%in using groundwater as the water source.In wet season and dry season,the eligible rate of central water supply was 62.79%and 64.84%respectively,it was 31.85%and 42.31%in separate water supply.The total colony count,total coli group,pH, nitrate nitrogen,manganese,iron,arsenic and fluoride were often seen exceeded the related limit.Conclusion The central water supply is not used so widely and microorganism contamination in drinking water is still a main problem in drinking water safety.
