Environmental Quality Evaluation of Surface and Groundwater in Yangling

Water plays an important role in everyday’s life of mankind. Faced with the water resources which is becoming exhausted day by day, how to improve the quality of water and its utilization rate became the focus of mankind.The authors selected different sections in the surface water and groundwater of Yangling, sampled monitored and analyzed.The items monitored involve NH₄⁺, NO₃^-, NO₂^-, PO₄^3-, F^-, S^2-, Cr⁶⁺, Cu, Pb, DO, COD_Mn, COD_Cr, BOD₅, pH, EC etc. The data received would be compared with different national standards, including sanitation standard of using water for life, the surface water environment quality standard Gb3838-88, the farmland irrigation water’s quality standard. The different water quality’s standard rate are obtained and evaluated.Finally, some suggestions and methods on the water pollution prevention of Yangling are put forward according to the result of evaluation.
