Cancer incidence was investigated in an area which has been affected by the illegal practices of dumping hazardous waste and setting fire to mismanaged waste. For the 35 municipalities of this area that are served by a Cancer Registry, municipal standardized incidence ratios (SIR) and hierarchical Bayesian estimators (BIR) were computed. Moreover, municipal spatial clustering and a Poisson regr...

The problems of waste disposal have always been with us. In biblical times, the residents of Jerusalem always burnt their wastes in the hideous Vale of Gehenna. This gave way to burial of waste or sometimes dumping it in shallow oceans. All too often the sewage pipes of the seaside towns did not even take the waste to the low tide mark; and the use of the deep oceans as a disposal site has been...

Degradation of urban environment and health hazard is directly associated with the unscientific handling of Municipal solid waste of India. Urbanization also contribute intensify Municipal solid waste generation. Source segregation of solid waste not only the fact to converge but also possible in maximum resource recovery from the waste. Waste management is a problem due to the ineffective mana...

Predicting the amount of water that may seep into waste emplacement tunnels (drifts) is important for assessing the performance of the proposed geologic repository for highlevel radioactive waste at Yucca Mountain, Nevada. The repository will be located in thick, partially saturated fractured tuff that—for the first several hundred years after emplacement— will be heated to above-boiling temper...

On August 22, 2005 the U.S. Environmental Protection Agency issued proposed new regulations for radiation releases from the planned permanent U.S. nuclear-waste repository in Yucca Mountain, Nevada. The goal of the new standards is to provide public-health protection for the next million years - even though everyone admits that the radioactive wastes will leak. Regulations now guarantee individ...

A coupled thermal, hydrologic and mechanical (THM) analysis is conducted to evaluate the impact of coupled THM processes on the performance of a potential nuclear waste repository at Yucca Mountain, Nevada. The analysis considers changes in rock mass porosity, permeability, and capillary pressure caused by rock deformations during drift excavation, as well as those caused by thermomechanically ...

Field, laboratory, and modeling studies of fractured rock have generated great interest from both fundamental and applied perspectives. Many practical applications of these studies are crucial for the exploitation of petroleum and geothermal reservoirs, the safe environmental management of groundwater, the isolation of radioactive waste in under­ ground repositories, cleanup technologies for ot...

Main effects of mining operations on the land and water resources while mineral are considered. Identify that intensive open-pit underground development deposits has resulted in disturbed natural environment, which, turn, have changed geomorphological hydrogeological structure region. Current stage determined terms Kryvyi Rih iron-ore basin. The analysis showed аs a result technical activities ...

Danger waste disposal systems are typically comprised a series of barriers that act to protect the environment and human health. The presence of several barriers enhances confidence that the waste will be adequately contained. This article is focused on one of barriers, bentonite buffer. Bentonite buffer intervene between the waste canister and the host rock. One of main tasks of the bentonite ...
