Description:
Accuracy of depth to water measurements is an issue identified by the Forum as a concern of Superfund decision-makers as they attempt to determine directions of ground-water flow, areas of recharge of discharge, the hydraulic characteristics of aquifers, or the effects of manmade stresses on the ground-water system. Perhaps the most extensive investigation into methods for measuring water levels in wells has been conducted by the U.S. Geological Survey. The U.S.G.S., in conjunction with 32 other federal agencies put together a "National Handbook of Recommended Methods for Water-Data Acquisition," which includes an entire section on water-level measurements. The following discussion is based on that document.
