Groundwater Simulation of Some Farm Nitrate Pollution along the Yellow River

The quality of groundwater directly or indirectly affects the living environment and health of human beings. Some farm in Zhengzhou city along the yellow area as the research object, investigated the regional hydrogeological conditions, by using Modflow in GMS and MT3D two modules model of groundwater flow and solute transport model, selection of nitrate as to simulate the pollution factors of groundwater pollutant migration law predict, simulate the nitrate pollution factor initial concentration of 25 mg/L, The migration rule, pollution range and concentration distribution of 1000 days, 5 years, 10 years and 15 years were selected in the simulation period. Finally, according to the prediction results, the pollution status of nitrate to groundwater environment is obtained.
