GIS Method
Several Wells were sampled & analyzed for TDS, NO3 and radioactive tritium (3H)
The observed values is converted into attribute of area objects through a point interpolation techniques that produce a map surface from the data values (TDS, NO3, 3H) recorded at a series of points (wells)
A Fuzzy Logic model was developed using modeling language and applied to define the most vulnerable aquifer location for contamination from surface
