Quality of nutrient data from streams and ground water sampled during water years 1992-2001
David K. Mueller, Cindy J. Titus
2005, Scientific Investigations Report 2005-5106
Proper interpretation of water-quality data requires consideration of the effects that bias and variability might have on measured constituent concentrations. In this report, methods are described to estimate the bias due to contamination of samples in the field or laboratory and the variability due to sample collection, processing, shipment, and...

2005, Scientific Investigations Report 2005-5137
Vast expanses of sedge fen in Schoolcraft County in Michigan's Upper Peninsula were ditched and diked in the early to mid-1900s to promote agricultural development and create waterfowl habitat. Unintended consequences of these actions were far reaching and included the deposition of large amounts of sand in the Manistique River....

This handbook provides information about the threat posed by earthquakes in the San Francisco Bay region and explains how you can prepare for, survive, and recover from these inevitable events. If you live or work in the region, you need to know why you should be concerned with earthquakes, what...
Water-quality assessment of part of the Upper Mississippi River Basin, Minnesota and Wisconsin — Ground-water quality along a flow system in the Twin Cities metropolitan area, Minnesota, 1997-98
William J. Andrews, James R. Stark, Alison L. Fong, James D. Fallon
2005, Scientific Investigations Report 2005-5120
As part of a national analysis of the effects of land use on ground-water quality for the National Water-Quality Assessment Program, the U.S. Geological Survey sampled wells along a flow system in surficial glacial aquifers in the northwestern part of the Twin Cities metropolitan area during 1997 and 1998. In...
