Ground water is sampled to assess its quality for a variety of purposes. Whatever the purpose, it can only be achieved if results are representative of actual site conditions and are interpreted in the context of those conditions. Substantial costs are incurred to obtain and analyze samples. Field costs for drilling, installing, and sampling monitoring wells and laboratory costs for analyzing s...

Since 1996, over 100 million tons of combustion by-products have been generated by U.S. coal burning power plants each year. Typically, about 1/4 of that total is used for purposes such as cement/concrete, structural fill, wall board and other products and applications. The remaining coal combustion by-products (CCB’s) must be temporarily or permanently stored. CCB’s are sometimes placed in ina...

ago, led to the reduction in habitat and the extinction or restriction of several species of beetles. Much later in the midnineteenth century, the arrival of Europeans and their cultivation practices modified the insect fauna of the American Midwest so profoundly that the event is as detectable in the fossil record as any ice age climate change. The lesson from the fossil record of insects is t...

The goal of this project is to examine the potential long term performance of the proposed aluminosilicate waste/storage form for the isolation and eventual direct disposal of the cesium and strontium separated from recycled nuclear fuel. In the first phase of this work, researchers will investigate the sintering procedure to prepare the drum-like aluminosilicate waste/storage form from the as-...
