Kolpin and published by . This book was released on 1995 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2001-12-01 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: The occurrence of volatile organic compounds (VOCs) in water is of nat. concern because of their high aqueous solubility, mobility, and persistence. Many are known or suspected carcinogens, esp. since they have been found in drinking-water supplies. VOCs were selected for nat. invest. in 1994. This report describes the invest. of VOCs in ground water, which has 3 objectives: to describe their occurrence, status, and dist.; to determine relations among VOCs in shallow ground water and natural and human factors; and to determine, compare, and contrast the occurrence, transform., transport, and fate of selected VOCs in the hydrologic cycle for several regionally or nationally important aquifer systems.
