Biohazards of Sewage Sludge Essay

Although both public relations and journalism requires extensive writing skills as well as being able to interview subjects and intake large amounts of information they do differ. People in public relations have a responsibility to not only inform the public, but they also try to influence audiences to benefit a certain company or organization.

Water contamination is vastly becoming an alarming issue across the world. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution (www.nrdc.org). Clean and plentiful water is the cornerstone of prosperous communities. Yet as we enter the 21st century, swelling demand and changing climate patterns are

Infections can be spread through many things, these include; food borne infection, person to person, water borne infection, airborne infection, insect borne infection and fomites.

The sources of infection can be divided in two main groups. These are exogeneous and endogeneous sources. A source of the infection is

Although sewage systems are able to provide a great deal of sanitation to water before it is released back into a source, the risk of raw sewage overflowing into water sources poses several issues. Not only can raw sewage contain harmful bacteria such as E. coli, it can also negatively affect aquatic life. Human waste typically contains high levels of nitrogen, phosphorous, and other nutrients that are useful for people but can cause many issues in an aquatic environment (Burkholder et. al., 2011). Much of these elements are removed during wastewater treatment, but if they are sent directly to a water source due to flooding, they can cause algae blooms and harm

Environmental Protection Agency (EPA) described the general treatment of wastewater and its two basic stages, primary and secondary. In the primary treatment most solids are caught in a screen, then the sewage goes to a grit chamber to settle small pieces of debris at the bottom, then through the sedimentation tank. Afterwards, secondary treatment removes a majority of the organic matter, eventually being chlorinated before reaching an effluent (EPA, 1998).

1. These health risks may be minor or major, and may even lead to death.

In the article, “The Sludge at the Bottom of the Sea,” author Damiano Marchetti explains where human waste is going once it leaves the sewers of New York City’s streets. The authors main claim is human waste being dumped into the Atlantic Ocean and how it has affected activity down on the sea floor. Marchetti continues on about how the EPC told environmentalists not to worry about the sludge, because it wouldn’t affect the ocean since it cannot reach the bottom. And lastly the author finishes up by stating how the incoming waste has increased the food production on the sea floor.

Such kind of waste emits radiations from tens to hundreds of years. These reactive radicals make the sand or the water contaminated. It is known as mixed waste. The mixture cause hazardous chemical reactions and leads to dangerous complications.

Although bearing the number 7, Resident Evil 7: Biohazard is actually the 11th installment in the Resident Evil series. Developed and published by Capcom, the game is the first entry in the franchise in which gamers play from the first-person perspective. RE7 was released worldwide for Microsoft Windows, PlayStation 4, and Xbox One in January 2017.

Hazardous waste and its proper disposal have become a major sociological problem today due to its capability of contaminating the area in which we live and its potential to be lethal to all living things. In order for the United States and the rest of the world to save itself from a potentially life threatening problem they must fix the causes which lead to the improper disposal of hazardous wastes and like materials. Some reasons that hazardous waste has become a problem in the United States today is due to the breakdown in enforcing laws for the proper disposal of such wastes, a lack of initiative on big companies behalf to spend money on proper disposal, and the ease of disposing of such wastes illegally.

Although the state of America’s water infrastructure is of great concern, the types of chemicals found in America’s tap water are equally as frightening. The passage of the Water Act in 1972 prevents the direct dumping of hazardous chemicals directly into waterways, and helps regulate quality standards of water. However, the Clean Water Act is has no jurisdiction on regulating indirect dumping of chemicals that integrates into water supplies. Pesticides and prescription drugs are the greatest cause for concern of indirect containments in America’s water supply (Olsen). An abundance of the harmful chemicals found in liquefied animals feces, used in large dairy states, have percolated into drinking wells that have caused serious infections (Duhigg). However, more harmful containments are infiltrating water supplies. Such containments include

the nature of any physical, biological and chemical agents they will be exposed to, for how long and to what extent;

In suspended growth processes, the microorganisms responsible for the treatment of wastewater are maintained in liquid suspension by appropriate mixing methods. Many suspended growth process
