Dynamic Analysis and Water Quality Evaluation of Groundwater in Dawu Headwaters Ground

Dawu headwaters ground is the uncommonly oversize headwaters ground in the north and it is very important to economic development and society stabilization of Zibo city. However, since it has been exploited, a series of problems, such as continuous descent of ground water level and serious pollution of water quality in partial district, appeared with the fast increment of water use scale. In this article, the exploitation and utilization status of ground water and dynamic change rule of water level are analyzed deeply and the cause of foundation and space-time distributing characteristic of petroleum pollution is discussed. The method and indexes of water quality assessment are chosen, and water quality status of the space-time sections in Dawu headwaters ground is synthetically assessed. In the end, the rational suggestions on water resources sustainable utilization are put forward.
