Groundwater Quality Research Based on PDA and 3S Technology

Investigation of groundwater quality is the basic research to examination of the status of groundwater resources, evaluation of the groundwater quality, groundwater carrying capacity and study of groundwater pollution. Under systems engineering and software engineering methods, this paper focuses on PDA and 3S technologypsilas application procedure in groundwater quality investigation and groundwater quality assessment system design. And it is tested in Jinghuiqu Irrigation District. Compare with traditional methods, the investigation become more efficient, more precise and more credible.
