Potential Health and Environmental Effects of Hydrofracking in the Williston Basin, Montana part of Case Studies
Hydrofracking is a controversial oil and gas extraction technique developed in the late 1940s to gain access to fossil energy deposits previously inaccessible to drilling operations. The process, "hydraulic fracturing", literally involves the smashing of rock with millions of gallons of water–along with sand and a undisclosed assortment of chemicals in order to bring gas to the surface.
Libby Amphibole Asbestos part of Case Studies
Libby, Montana, a small town nestled in the northwestern corner of the state, is a humble town, a great destination for anglers and hunters. What many people don't know about Libby, is the lurking danger hanging over the heads of the 3,000 or so Libby residents. Located nearby is an old vermiculite mine that has created a health hazard dealing with asbestos. The old mine was used for acquiring vermiculite, that was used for insulation, shingles, and other construction materials. Imbedded in the vermiculite is a form of asbestos that was released into the air when the vermiculite was processed, creating an abundance of the fibers released into the atmosphere around Libby. The health risk, amplified by human activity, has always been a health hazard due to natural geologic deposits of vermiculite containing asbestos, in and around the Libby area.
Asbestos at Thetford Mines, Quebec Canada part of Case Studies
After being the focal point for the economies of nations such as Canada for a century, the asbestos industry looks to be all but dead. The health hazards that this silky-white product presents are now seen to outweigh the benefits of its fire, rust, and rot resistance, tensile strength, and sound absorption.
Health Effects of Coal Combustion In China part of Case Studies

Asbestos in the Home part of Case Studies
This web page it designed to provide easy access to information about asbestos in order to spread awareness. Asbestos has become a major environmental health hazard. It has been used in many industrial and commercial products that can be found in the home and in the place of work. When asbestos is inhaled it causes sever damage to the lungs which can lead to major health problems including emphysema and, in cases of high exposure, lung cancer.
Volcanic Ash: More Than Just A Science Project part of Case Studies
The term "volcano" has its origin from the name of Vulcan, the Roman god of fire. However, volcanoes are a result of processes of the earth much older than Roman mythology. While volcanoes may be fun to construct for science class or watch on television, the real consequences of volcanic eruptions can be harmful and serious. Some of these consequences include fires, structure damage, and differences in climate. One of the most deadly effects of a volcano is the ash coming from the eruption, which carries poisonous gases that are harmful to humans, plants, and animals alike.
