Based on research of the environmental problems of groundwater in northern Shandong plain in the past 10years, the impact of human activities on the groundwater environment was analyzed, including shallow groundwater pollution and aquifer dewatering, and its distribution, formation of law and development trend. The pollutants of shallow groundwater in the northern Shandong plain included nitrogen, heavy metal such as As and Pb, and organic. The deep confined aquifer dewatering occurs mainly in Dezhou where deep groudwater exploration have last for a long period. The deep confined aquifer dewatering triggered land subsidence. The shallow groundwater dewatering occurred in Guanxian and Ningjin where shallow groundwater was the main water supply for agriculture. Through the study on the distribution, causes, trends and its hazards of environmental problems of groundwater in study area, the paper raised appropriate precautions and sustainable development strategy.
