Why Do We Continue In Contaminated Water?

2. What are examples of bacteria and pathogen of concern in water that can cause illness?

Being a city beach, Bondi is an easy target for water pollution. It is swam in by millions of people every summer and is a major landmark for Australia and is an iconic beach. After looking into previous experiments on the health effects of swimming at Bondi Beach, it became clear that there are major concerns for the health of citizens; causing less people to swim at the beach. The main health worries are while swimming, although not infections from being in the water, but drowning. However, after a large downpour of rain, the water is not recommended to swim in. I want to see if swimming in Bondi beach has negative effects and if we should be doing it with little knowledge of how our body might react to the bacteria and pollution in the water.

This situation showcases the major dependency on the unique physical and chemical properties of water by displaying the results of water contamination. The switch from Detroit to Flint water system proved to be a fatal decision as the chemical and physical properties of the water were altered by both the iron and lead metals. The addition of high levels of chloride left the water exposed to contamination of lead and iron. The corrosion of the pipes occurred when the chlorine disinfectant reacted with the elemental metals of iron and lead. The chemical property of water was altered with these high levels of lead, chloride, and iron. This contamination also left the water with different physical properties such as a reddish-brown colour and a pungent odour as opposed to a colourless and odourless liquid. The manipulated physical and chemical properties of water led to irritability, developmental delay, learning difficulties, hearing loss, and many more. Thus, this situation showcases how living things depend for their survival on the unique physical and chemical properties of water as with these alterations it can lead to lethal consequences.

as others, but all are harmful. They vary due to the amount they contain of

Bioassays, Daphnia magna, were used to monitor water for the presence of toxic compounds in various water samples, including samples 1 mile upstream from the Fletcher’s Paint dump site and one mile downstream. A bioassay is a living organism that serves as a detector for toxins. It is hypothesized that if the Daphnia mortality rate when exposed to water samples from various locations is higher in greater solutions, then their deaths' indicate that the water contains toxic compounds due to the harmful toxins that originated from human pollution. This is the same hypothesis for the Fletcher’s Paint experiment.

Contaminated water poses health risks on humans, pets, wild animals, and farm animals. (Mcdermott-Levy 2013)

The chemicals found in water can be dangerous toward our health. We live near the Great Lakes which supplies 20% of the World’s fresh water. It also has chemicals that threaten the life evolving around the fresh water. There are medical drugs that are being introduced to the fresh water lakes. Stuff like antibiotics and steroids. These pharmaceuticals are posing danger for the environment. This could affect the lake life,s growth.

Another way that water can be polluted is with chemicals from factories. Factories use water from streams, river, and lakes to power and cool off their machinery. This used water contains many chemicals from the factory processes that are released back into the normal water (Lenntech, 1988-2016). This released water is also warmer, causing the whole body of water to heat up. This causes lower oxygen levels, which can disturb the organisms living in the water (Lenntech, 1988-2016).

The contaminated water has protozoan-a microscopic organism, oocyst-is a parasite protozoan like malaria, viruses, and bacteria. Illnesses such as West Nile and Dengue Hemorrhagic Fever have also been reported from poor run off conditions. (Gaffield & Jackson, 2003) As stated in the American Journal of Public Health, "Approximately 99 million people in the United States have acute gastrointestinal illnesses each year, at a cost of billions of dollars, and 6% to 40% of these illnesses may be caused by contaminated drinking water.". Another problem found in contaminated drinking water is Nitrogen. High amounts of nitrogen can bring the risk of Methemoglobinemia-is an oxidized hemoglobin that can not send oxygen to the tissues of the body, the symptoms include shortness of breathe and blueness of skin. It has also been linked to and increase in miscarriages. Copper, Zinc, and Lead, which also have ill effects on humans, can be found in mostly urban areas with so exceptions. These are just a few of the contaminates that are caused by uncontrolled storm water run off. (Gaffield & Jackson,

When something is added to fresh water that makes it unclear and unsafe, it is called fresh water pollution. In Hawaii, there are two big types of fresh water pollution. One type is point source water pollution and the other type is nonpoint source water pollution. Nonpoint source water pollution is important to Hawaii and other nations because according to the United States Environmental Protection Agency, nonpoint source pollution is now the single largest cause of the deterioration of our nation's water quality.

The researchers stress that studying water (aquaculture and sewage) is vital in understanding and stopping superbugs since water connects us all -- humans, animals and nature. Vittecoq explains: "Limiting water contamination may be key to controlling the spread of antimicrobial resistance in natural ecosystems, so a first important step could be to limit water contamination through the development of improved wastewater treatment."

Clean and healthy water is key to keeping our bodies and environment healthy. Having un-sanitized water can affect many different things from human health to the environment. What I will be discussing is safe and healthy water and how it affects not only us but the environment.

To develop a better understanding of water contamination, a field comparison between two separate water sources was conducted. The first water sample was gathered from the Simmons Park Pond and the second from a NES water fountain. The data gathered from this experiment was used to answer several questions regarding the prevalence of contamination in nearby water sources. The field analysis ultimately concluded what contaminants had the greatest prevalence, thereby exemplifying the defining differences between the two water sources.

The water quality of the U-high creek was recorded as excellent. However, that is not that is not the case for every body of water. Some lakes, rivers, or streams are polluted. One way humans pollute the water is chemical runoff from industrial processes. (Lenntech,2016). Some chemicals like sulfuric acid get released into the air and come back down as acid rain. If enough acid rain gets into the river it can start to kill organisms in it. Pesticides from crops is another way that humans can contaminate the water. (Lenntech,2016). When it rains the excess chemicals get washed into the river. The chemical formaldehyde is used in pesticides and is highly toxic to aquatic life. So, if it gets into the river then anything exposed to it will die.

One of the most important natural resources we have on this planet is water. Water covers roughly 70 percent of our planet and is the very foundation for every single species on earth. We as humans, rely on water more than any other resource on the planet and we simply can’t live without it. Although water is abundant around the world, clean water for millions of people is inaccessible. Around the world, there are people struggling to get water yet along clean water and it greatly affects our health. Improving clean water supply and sanitation, and better access to clean water resources, can increase countries’ economic development and can contribute greatly to poverty reduction and overall people’s health.
