Estimating Generalized Flood Skew Coefficients for Michigan

Description: From purpose and scope: The purpose of this report is to compare and evaluate four methods of estimating flood-frequency skew coefficients for Michigan. These methods are based on use of (1) the generalized skew map of the United States, (2) maps showing lines of equal mean skew of Michigan, (3) mean regional station skews, and (4) skew-prediction equations.

Ground-Water Contamination at Wurtsmith Air Force Base, Michigan

Description: 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.
