Beijing-Air-Pollution--011.jpg Pollution (Bioremediation) Last Updated on 2014-11-09 17:40:04 Pollution is environmental contamination that results in harm or death to living organisms. Most pollution is in the form of chemical additions to air, water or soil; however, in modern times starting in the mid-twentieth century noise and light have been considered as pollution sources. Most pollution is man-made, with natural fluctuations in atmospheric composition, surface water bodies and soil considered temporal gyrations in the Earth's natural history. The chief driver of pollution is the massive growth in human population, which induces the proximate causes of intensive agriculture and extraordinary industrial output. The United Nations and the Blacksmith Institute[1] are two prominent organisations that tabulate locales of the greatest pollution intensity; while their listings do not correspond precisely, the overlap countries that both entities agree are the worst polluted...

Biorem img02.jpg Bioremediation (Bioremediation) Last Updated on 2011-01-12 00:00:00 Many methods are employed by public and private agencies to clean up pollution at Superfund and other sites. Some, like bioremediation, are considered new or innovative. Such methods can be quicker and cheaper than more common methods. If you live, work, or go to school near a Superfund site, you may want to learn more about cleanup methods. What is bioremediation? Bioremediation allows natural processes to clean up harmful chemicals in the environment. Microscopic “bugs” or microbes that live in soil and groundwater like to eat certain harmful chemicals, such as those found in gasoline and oil spills. When microbes completely digest these chemicals, they change them into water and harmless gases such as carbon dioxide. How does it work? In order for microbes to clean up... More »
ContentImg.jpg National Priorities List Last Updated on 2008-08-21 19:47:05 The U.S. Environmental Protection Agency characterizes the National Priorities List (NPL) as a dynamic compilation of national priorities among the known releases or threatened releases of hazardous substances, pollutants, or contaminants throughout the United States and its territories.The NPL is intended primarily to guide the EPA in determining which sites warrant further investigation. From this web site, you can locate NPL sites, check their cleanup progress, and get information on new and proposed NPL sites.Sites are listed on the National Priorities List (NPL) upon completion of Hazard Ranking System (HRS) screening, public solicitation of comments about the proposed site, and after all comments have been addressed. More information about these steps in the process can be found here: ... More »
