A Method for the Fast Security Evaluation of Surface Drinking Water Sources in Western Mountain Areas

Abstract

Due to the nonpoint pollution of drinking water sources in western mountain areas and the lack of relevant monitoring data, four security indexes (water quality risk, water supply and demand ratio, water and soil erosion and flood control) are used to describe the water quality, water quantity, ecological and engineering safety of drinking water sources respectively. The fast-evaluating index system related to the security of drinking water sources in western mountain areas is further constructed. Additionally, this system was applied to the security assessment of a drinking water source in Cengong(a poverty-stricken county) of Guizhou Province, and a positive result was accquired. The research is of important theoretical and realistic significances in exploring and pushing the protection and pollution control of drinking water sources in western mountain areas.
