Analysis on status of drinking water in rural of Fujian

Objective To realize the status of drinking water in rural of Fujian.Methods Drinking water sites were stratified and sampled randomly,and water from both the end of centralized and decentralized water supply locations were tested.Results In rural of Fujian,51.29% of drinking water were supplied by centralized water supply system,and 48.41% by decentralized water supply system.Reservoirs were the main sources of centralized water supply(38.06%),while shallow wells were the main sources of decentralized water supply(49.49%).41.4% of drinking water were collected from surface water locations,and 58.6% from underground water locations.The qualified rates of water samples were 54.8% during the year,53.2% during plenty water period and 56.5% during low water period,respectively.The qualified rates were 61.7% for centralized water and 44.0% for decentralized water;59.4% for surface water and 51.1% for underground water respectively.Among all water samples,69.8% met the standard of total coliform and 85.6% were qualified for total bacteria.Conclusion Nearly half of rural population in Fujian are supplied with decentralized water which has a low qualified rate mainly due to microoganic contaminant.The technical guidance for rural water supply in Fujian should be improved.
