Determine groundwater elevations at site monitoring wells and draw groundwater elevation contours for the Former Radiator Factory site using monitoring well information and depth to groundwater measurements.

Learning Goal: I’m working on a environmental engineering question and need an explanation and answer to help me learn. Determine groundwater elevations at site monitoring wells and draw groundwater elevation contours for the Former Radiator Factory site using monitoring well information and depth to groundwater measurements. Assume depth to groundwater is recorded as depth from the top of the INNER CASING. Estimate the hydraulic gradient?
Requirements: proper calculation and contour map
