Water Contamination Using The Filtration Process

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

Not only is pollution the cause of the death of many organisms essential to ecological balance, but human drinking water has also been affected.

While steps have been taken by the government to help bring standards to water treatment and wastewater treatment plants some of the contaminants seep into the water supply after it has been filtered. The US Environmental Protection Agency has issued standards for drinking water with policies like the Safe Drinking Water Act of 1974, but the standards are not foolproof and some municipalities are not in compliance with the standards. Another problem is the cost of setting up better filtration systems to catch some of the contaminants that are not being filtered at the present time.

I was fascinated by this experiment that we recently did on water contamination, tap water versus expensive bottled water. Our water is tap well water. While exploring the topic futher, our research area took place on our kitchen counter where we observed how the test chemicals reacted with the tap water versus the bottled waters. We needed to follow the directions thoroughly, so we got accurate results. We started with test strips of ammonia: all three glasses of water contained: 0 mg/L of ammonia, 0 mg/L of chloride. The 4 in 1 showed: Tap water; 0 mg/L, total alkalinity; 10.0 of total chlorine, 120 mg/L of total hardness. The Dasani revealed 40 mg/L of total alkalinity, 0 mg/L of total chlorine, 0 mg/L of total hardness. The Fiji

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

The contamination of water and drinking supplies with high concentrations of nutrients from animal waste has fatal effects on different organisms. “Elevated nitrates in drinking water...hinders the ability of the...blood to carry oxygen” (Hribar 4), which can cause serious health conditions such as birth defects, miscarriages, and can even lead to death in seniors and infants. Although nitrates may have the greatest consequences on younger and older individuals, adults that consume tainted water develop increased risks of “cancer and non-cancer diseases...diabetes...and neurodevelopmental defects” (Halden and Schwab 16). Contaminated drinking water poses a serious threat to human health, and can affect people’s happiness and quality of life.

Laundry detergent, vegetable oil, and vinegar were all used in my experiment to determine the reaction to water and filtration. The laundry detergent had a brownish color and a small amount of soap bubbles were present when stirred after filtration. The oil had a brown color from the dirt, but no odor was present and the oil barely showed signs of contamination. Vinegar had a brown murky color despite the very strong odor was not as strong as it was before filtration. There were identical and different amounts of contamination levels as I went through experiment 3. Ammonia had a reading of 0mg/L for all three water samples of tap water, Dasani, and Fiji bottled water. Roughly every other reading for my experiment turned out different for at least one water sample in relationship with the contaminants. Fiji lead in my test results for phosphate with 100ppm, nonetheless tap water lead in all other contaminants.

Its technicians understand that there are more than 20 common pollutants in America’s water supply, varying city by city. Some of the most common contaminants include:

The purpose of this lab was to build a filter to clean dirty water and change it to clear from our hypothesis.Some of the types of water pollution are like air pollution and water pollution is cross-media contamination that is the different types of pollutants that may enter the water from land or air (Chiras, 2016). The nonpoint sources of pollutants is from places like the forest, farms, lawns, and urban streets because they use substances like fertilizers, salts, grease, and litter the land that causes water pollution. The point sources of water pollution comes from factories, power plants, mines, and other things (Cantu, 2016). An example of water pollution sources can be from pipes dumping waste into water that they should not be which

Water is a critical source that is utilized by most living things on Earth to support it ways of live. The usage of water ranges from basic household needs to agricultural purposes. Water is one of the resources on the Earth that is becoming more and more scarce and the water available for usage is being further contaminated by pollution causing sickness and death.(World Health Organization).Countries are experiencing droughts affecting the water supply needed to maintain irrigation, thermoelectric power, and public supply. The definition of water pollution is the result of when too many toxic materials are present, in which negatively impact the water to be unsafe for its intended purpose, which may be drinking to industrial processes

In the past, we believed that a filter would sift out any and all impurities in a given water source. We didn't realize that separate filters were needed for different things. This lab exemplified how a filter works and what type of things can help to clean water. We believe that had we spent more time constructing the bottle filter, we would have received more positive results. To conclude, in some cases, the filters tested were able to clean certain contaminants from contaminated water. In the more polluted sources, it was evident that not all pollution was filtered out. It is highly unadvisable for anyone to conduct this experiment intent of drinking the

With the rising popularity of bottled water, which at that time was a billion dollar business, the sales of Clorox’s company Brita water filtration systems began to decrease. Instead of being defeated by this, Clorox saw an opportunity to reposition its Brita brand as a “green” product to replace plastic bottled water, which was causing landfills to become clogged. By using Brita water filtration systems instead of bottled water, consumers would prevent millions of empty bottles each year from being dumped into landfills and Clorox saw this as an opportunity to revive the fast dying Brita brand. By conducting a successful marketing campaign, which promoted the green attributes of its water filtration system, educating customer about bottle waste and its affects on the environment, and encouraging them to switch to the Brita brand, sales of Brita water filtration system began to rise. To get consumers excited about the product and involved in the bottle “saving” process, the company created a website called FilterForGood which allowed consumers to pledge that they would reduce waste by switching to Brita. It also totaled the amount of bottles saved so that consumers could see how they were saving the environment and encourage them keep on using the Brita water filtration system.

The purpose of this report is to propose a solution to the problem of reduced drinking water quality due to chemical pollution. Some bodies of water in the United States are becoming polluted from chemicals and restrictions are needed to protect drinking water quality.

Water analysis alone cannot maintain clean water and combined with periodic review and policy compliance is vital. Reviewing and acceptance of any type of water treatment facilities form a necessary basis for the maintenance of quality drinking water. According to the WHO, quality drinking water contains no pathogens and bacteria indicative of fecal matter and that regular water samples should be taken and examined to ensure good quality drinking water. The presence of Escherichia Coli in water is a potential indicator of fecal matter. Clean drinking water must not contain any trace of bacteria once the sample is analyzed. The provision ensures that, quality, pathogen free

Water is definitely related to the economics of both developing and developed countries where it affects energy and food production, industrial output, and our environment quality. Water is today considered to be a vital and limited resource. With agriculture, livestock, and energy consumption comprising over and above 80% of all water for human use, demand for fresh water is expected to increase with population growth, further stressing traditional sources. Furthermore, growing numbers of contaminants are entering water supplies from human activities and public health and environmental alarms now persuade to cleanse waters considered in the past to be clean. Globally, confirming the sustainable water management can be achieved by developing appropriate water treatment techniques.So what are the challenges? The decontamination of water without the use of chemicals or the production of toxic by-products; the removal of low-concentration contaminants in high backgrounds of potable constituents at lower cost; and the re-use of wastewater and water desalination from sea and inland saline aquifers.
