	1	In-situ observation and transport modelling of arsenic in Gangetic plain,India显示文摘The focus of this study is to investigate the arsenic movement and impacts on the residual concentrations on groundwater pollution load.The Gangetic plain area in the Ballia,Uttar Pradesh is selected as study area,which is also reported to extreme arsenic pollution in soil-water system.A modelling approach is developed to assess the arsenic flux in partially saturated zone using data of soil texture,soil hydraulic properties and stratigraphy.Soil type,slope,and land-use cover is considered for estimating the transient flux at the top boundary from daily precipitation and evapotranspiration data of the study area.Solute transport in the subsurface is predicted by the mass transfer equation,which is derived by integrating Darcy's law with the equation of mass balance.The arsenic profiles of varying hydrogeological conditions associated with different locations in the study area are presented as breakthrough curves.The results shows that the arsenic transport is dominated by the advective flux and strongly depends on the soilmoisture flow conditions.Which may increases the arsenic load to underlaying groundwater resources.The simulated results suggest that mobility plays a vital role arsenic transport as well as on adsorbed arsenic concentration in subsurface.Likewise,the adsorption isotherms show that the high peak curve for Bairai and low at Sikarderpur.A higher pollution risk is observed in the Belthara Road,whereas a lower vulnerability is computed in the north and northeast regions.This study can help in strategising sustainable groundwater management and protection planning of identified regions of India.
