Elevations certificates for monitoring wells at Lincoln and Long's lot on Monday.

The State standards regarding these monitoring wells require absolute elevations to the nearest 0.01'. Although our GPS receivers with redundant readings and careful procedure will give us accuracy close to that, I was wondering what was the purpose of that kind of requirement. Steve Baker, our local "Hydro-head" explained the need for accurate wellhead elevations in order to develop sub-surface water flow models. The sub-surface water tends to follow the contours of the ground surface, so in areas where there is a lot of topographic variation, the hundredth of a foot might not be so important, but in flat areas, just as with surface drainage patterns, the direction of subsurface flow is harder to determine.  By measuring the invert elevation to the water in a scattering of wells you can map the invisible underground topography of the aquifer.
