Abstract
The accuracy of depth to water measurements is an issue identified by the Regional Superfund Ground Water forum as a concern of Superfund decision-makers as they attempt to determine direction of ground-water flow, areas of recharge or discharge, the hydraulic characteristics of aquifers, or the effects of manmade stresses on the ground-water system. The wetted graduated steel tape, electrical and air line methods are discussed along with frequency of measurements. The graduated steel tape method is considered to be the most accurate for measuring the water level in nonflowing wells.
