Water Quality Assessment Research Of Rural Dirnking Water In Lujiang County

The problem of rural drinking water safety, as one of key problems the human-beingsare facing, is concerned with the living and health of the mankinds themselves. The lack offreshwater resources can hardly be changed, but keeping high-quality water resources canbe carried out. The Chinese government has definitely put the enforcement of rurualdrinking water safety into the outline of china’s the Eleventh Five-years Plan and theoutline of china’s the Twelfth Five-years Plan programme which has estimated that thisproblem will be solved basically in2020.Lujiang county, the north of which lies near Chao Lake,the south of which lies nearYangzi River,is the key part of Hefei economic circle. It has deep-seated agricultural basis,and powerful delayed effect of industrial development. The research doing good to theenvironmental administration of Chao Lake valley, provides the scientific basis for waterimprovement and drinking water manufacture of Lujiang county,which plays a beneficialrole of hygienics in safeguarding the health of the people.This paper studies the drinking water quality conditions of39rural areas in Lujiangcounty,and makes an analysis as the basis of GB5749-2006according to five kinds ofindexes such as microbial indexes, perception and general chemical indexes, organicpollution indexes,carcinogenic indexes and general toxicity indexes which contain22minor indexes.It also combines single-factor evolution method with Nernerow indexmethod,does a weighted summation of the integrated indexes of different kinds and finallycalculates the general assessment index of water bodies. By means of this method, it makeswater weighting coefficients of tap water of all the county,definies the grades of waterquality of all the waterworks and the significance of hygienics,and also clarifies overproof items. Simultaneously, it, aiming at the problems of water quality assessment of ruraldrinking water in Lujiang county, provides the scientific countermeasures from the threeaspects such as enforing the management of manufacturing drinking water, applying theenhanced treatment technology and providing prevention and cure of water sourcepollution, and finally offers the reference for rural drinking water safety in Anhui province.
