Analysis And Actually Appraising On Drinking Water Quality Of City

Drinking water is the foundation and the lifeline of the city environment, city drinking waterquality has a direct impact on people’s health and quality of life. At present, type of surface waterresources in the world are faced with the pollution problem. Once the water resources pollution,available water resources reserves have been reduced rapidly, caused great inconvenience, evenmade a direct threat to the safety of people’s life, influence of environmental safety of society.Longyan City gradually use surface water source (Lake and reservoir water) as the mainsource of water supply and correspondly close groundwater water supply in the region. Now,groundwater resources and surface water resources cross supply has formed. Therefore, surfacewater quality plays an important role in the city water supply system. So, taking Huanggangreservoir in Longyan city of Fujian Province as the research object in this paper, concludelivestock and poultry manure pollution is the main pollution source by field investigation and datacollection; clear its water quality present situation through the basic quality data of the monitoringpoints; reveal the degree of eutrophication and the current situation of water environmentalcapacity. And the solving measures are put forward according to the results of the analysis, inorder to protect drinking water sources, further improve water quality.
