Ground water pollution modeling through time series 3D modeling

Ground water during its conduit through soil leaches pollutants and getting itself contaminated in the process. Regional scale treatment is required to contain such spreading of contamination. Present study is one such study conducted by SBL geospatial team for an environmental management firm at Ohio area of United States of America. Ground water samples were collected from 1998 to 2012 and analyzed for ethane content. It was for an environmental management exercise to demonstrate that ethane content can be contained by time duration of 14 to 15 years. All the well locations were plotted initially in a 2D environment and later converted to 3D environment by implying well screen height with respect to mean sea level and treated as z element in the analysis. Then the spread of ethane horizontally and vertically is established by a complex 3D model plotting of the ethane concentration in µgm/liter derived through analysis of collected water samples. Later 3D contours of the ethane concentration were derived from the created 3D surface model.This analysis was iterated for monthly data of ethane concentration for a period of 1998 to 2012. Later time series analysis of the ethane concentration has done and found that as duration increases ethane concentration was reducing and is fully contained by 2012.
