Environmental Pollution
Pollution is one of the major ways through which human activity affects the physical environment. This form of human activity has attracted considerable attention in recent decades because of global climate change. In the United States, pollution or damage to the environment due to human activity continues to be a major issue for the Environmental Protection Agency (EPA). The agency has created the National Priorities List (NPL), which shows national priorities of environmental issues and projects brought about by pollutants, hazardous substances, or contaminants throughout the country (EPA, 2023). The list guides the agency in decision-making on sites that require urgent action to prevent environmental damage or harm.
One of the Superfund national priorities listed by EPA is PCE Carriage Cleaners, which is situated in Bellevue, Nebraska. The site is located nearly 0.7 miles west of the Missouri River (EPA, 2022). Similar to other Superfund sites, this site involves contamination by toxic substances, which in turn poses risks to public health and the environment. PCE Carriage Cleaners was identified as a Superfund site in 2017 after EPA noted that groundwater at this site was polluted by tetrachloroethene (PCE), which is one of the ingredients in dry cleaning substances. Carriage Cleaners is a former dry cleaning...
…the high levels of PCE and TCE in this Superfund site. As part of the long-term plan and process, EPA has successfully installed 21 vapor mitigation systems to address contaminated indoor air. 13 of these systems have been installed in residential properties while the remaining eight in commercial buildings.In addition to the installation of vapor mitigation systems, EPA recognizes that clean-up of contaminated groundwater is essential to addressing the environmental effects of PCE and TCE on this site. As a result, the agency has evaluated other federal and state cleanup programs relating to this Superfund site. Currently, the agency has concluded that other cleanup programs…

Pollution From Mining Activities How serious is the pollution that results from mining activities? How clean are the coal mining activities in Kentucky, West Virginia, and other Appalachian areas where mountaintops are stripped away to get at the coal? What other mining activities cause pollution of the air, the land, and the waterways? This paper will delve into those mining activities and report the pollution that results from those strategies. The Pollution
Pollution Unfortunately, there is quite a diverse array of forms of pollution of the water and the air on Earth. The paper will only focus upon a few types, with the intention of providing insight regarding the results of the pollution upon various forms of life on the planet. As far as any type of pollution, formal environmental agencies, whether public, private, or of the government, all have standards by which
Pollution Control With growing population in the city, greater pressures on infracture and natural resources has affected the environment in greater ways. Increase in population causes infracture to deteriorate, traffic congestion, lower air and water quality, and loss of open space. Population increase brings with it more vehicles on the roads that put greater emissions in the air and greater pollution problems that affect the land and water quality. All of
" (Norris, 2004) SUMMARY & CONCLUSION Pollution prevention and reduction in the use of toxics and reduction in waste are greatly at focus for the Environmental Health and Safety Guidelines (2007) which are guidelines that can be specifically tailored to the established hazards and risks for each individual process depending upon the various factors that are applicable at each site. The Resource Conservation and Recovery Act (RCRA) is a federal environmental law
D.), Miller Brewing was the first brewery to "recover excess carbon dioxide from the brewing process for sale…to food processors for refrigeration purposes." Likewise, Miller resells its brewer's yeast to food processors instead of wasting it. The brewery is saving money by administering its pollution prevention program. Taken together, source reduction and recycling annually are saving the company $3 million (North Carolina Division of Pollution Prevention and Environmental Assistance n.d.). "Capital
Pollution in the environment has become an important subject for consternation in today's world, where pollution of all kinds affects the daily lives of people as well as the environment in such a way that most people find it difficult to continue their normal routines on account of the pollution. Pollution can affect either the air or the water of our Planet Earth, and although the pollutants that are emitted
