"The purpose of this report is to present the results of a condition survey performed at Wurtsmith Air Force Base (WAFB), Michigan, during 1-5 May 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).

From introduction: The U.S. Geological Survey, at the request of the U.S. Air Force, began an investigation of geologic and hydrologic conditions at Wurtsmith Air Force Base in September 1979. The investigation was prompted by the discovery that an underground storage tank containing trichloroethylene (TCE) had leaked, contaminating Base water-supply wells. Subsequent information suggested that the trichloroethylene had moved off-Base.
