Plan of Study for the Northern Midwest Regional Aquifer-System Analysis

From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines.

Coal-Mine Accidents in the United States and Foreign Countries (open access)

Coal-Mine Accidents in the United States and Foreign Countries

From Introduction: "The lack of comparable and accurate statistics of coal-mine accidents in the united States as a whole led the Bureau of Mines in 1911 to undertake the collection of such data. The mining departments of the leading foreign coal-producing countries have long taken cognizance of the importance of statistics. The bureau feels that in presenting the tables embodied in this report it is offering the and comparable statistics of coal-min accidents for the country as a whole that have ever been published."

Disaster Tax Relief for the Midwest (open access)

Disaster Tax Relief for the Midwest

The Midwestern Disaster Tax Relief Act of 2008 is intended to assist with the recovery from the severe weather that affected the Midwest during the summer of 2008. The Jobs, Energy, Families, and Disaster Relief Act of 2008 includes some similar provisions, but these are not limited to the Midwest disaster. The disaster relief in the three bills is similar to that provided to assist with the recovery from the 2005 hurricanes and the 2007 Kansas tornadoes. This report broadly discusses the disaster relief provisions in other relevant legislation.
