Delineation of drinking water source protection zones for public-water-supply springs in western Cache Valley, Cache County, Utah

Source of water is the beginning of rural drinking water projects, safe water source is the key to rural drinking water safety. Status of rural drinking water source in china and laws and regulations on rural water conservation were analyzed. The population of centralized water supply accounts for 51% of the total population in rural areas in 2008, centralized water supply 49%. Groundwater source accounts for 57% of the population of centralized water supply projects in rural areas in 2008, surface water sources 43%. China has a relatively sound legal system of drinking water source, including basic law, general law, administrative regulations, local regulations.The paper draws a conclusion that sources of drinking water in rural areas is mainly groundwater, water conservation is short of specific laws and regulations and not suitable for rural area,it is necessary to improve laws and regulations on rural water conservation, government must assume responsibility for rural water conservation, especially financial investment and public policy support.

The article aimed to find the causes of microbial contamination of drinking water source, by exploring the influencing factors of water on the incidence of diarrhea in children. Random stratified-cluster sampling was used to study Li and Han communities of rural Lingshui County with regard to water quality and environmental sanitation. Water samples were evaluated for microbial contamination using National Standard of the People's Republic of China and World Health Organization drinking water standards. Data were compared between ethnic groups. Li communities had more contamination than Han. The correlation between the frequency of diarrhea among children and the presence of microorganisms in the water was positive, for both total coliforms and Escherichia coli (E. coli). Regression analysis showed the substandard risk factors of total coliforms for source water were type of water supply (OR = 3.508) and garbage disposal methods (OR = 2.430). For E. coli, risk factors included the source of water supply (OR = 2.417); depth of wells (OR = 0.536) and distance of wells from the cesspit (OR = 0.723). The content of bacterium in drinking water source was high in the rural county. Water from open wells had higher contamination rates than water from centralized systems and tube-well sources. Improvement of water supply and environmental hygiene would decrease diarrheal diseases among children under five.
