The historic stream flooding and intense rainfall across the upper Mississippi River Basin during summer 1993 had an immediate effect on near-surface unconsolidated aquifers by raising the water levels closer to the land surface. The objective of this study was to determine if this flooding also had immediate effects on ground-water quality. Water samples were collected during September and October 1993 from 110 wells completed in near-surface unconsolidated aquifers and were analyzed for herbicides, herbicide metabolites, inorganic nutrients, and volatile organic compounds. The results of these samples were compared with those obtained during summer 1991 or 1992. Water samples from the Missouri River alluvial aquifer had a fourfold increase in the frequency of herbicide detection. There also appears to be a relation between increases in total herbicide concentration and the occurrence of stream flooding near a well. Water samples from wells that had at least a 20% increase in dissolved-oxygen concentration had the greatest frequency of substantial changes in total herbicide concentration and substantial increases in nitrate concentration.

The goal of this study is to assist in program management by pointing out problems, both recurring and unique to 1993, which hamper an effective response to natural disasters. Starting from a historical summary of flooding on the upper Mississippi and lower Missouri rivers, it then describes 1993's disaster. Next, the general approach of the White House and Congress to flood recovery is examined. The activities of individual U.S. Department of Agriculture agencies also receive attention. Most of the document focuses on the Soil Conservation Service's flood recovery program, new wetlands and levee policies, and the vexing problems encountered in this work. Finally, the Service's work in each of the nine flood states will be discussed in detail.

The flood that affected a third of the United States during the summer of 1993 was the nation's worst, ranking as a once-in-300-years event. It severely tested national, state, and local systems for managing natural resources and for handling emergencies, illuminating both the strengths and weaknesses in existing methods of preparing for and dealing with massive prolonged flooding. Through detailed case studies, this volume diagnoses the social and economic impacts of the disaster, assessing how resource managers, flood forecasters, public institutions, the private sector, and millions of volunteers responded to it. The first comprehensive evaluation of the 1993 flood, this book examines the way in which floods are forecast and monitored, the effectiveness of existing recovery processes, and how the nation manages its floodplains. The volume concludes with recommendations for the future, in hope of better preparing the country for the next flood or other comparable disaster.
