Water Quality Research Literature Review

The purpose of this paper is focus on the municipal water issues in Canada, especially the main factors to affect water quality in Canada. Although there is a common perception that Canada has the second water quality and water quantity in the world, Canadians are among the highest water user per capital by comparing with other countries. Furthermore, clean water is essential to life and our health, so federal government plays an important role to make sure our water suppliers are safe in Canada.

One example is aquatic life. Animals use up dissolved oxygen to carry out respiration for cellular processes and bacteria use up oxygen to decompose and break down organic wastes removing oxygen from the water to breathe. Therefore dissolved oxygen levels are lower when a body of water contains a lot of decomposing material. Plants also affect dissolved oxygen content as they release oxygen as a bi product of photosynthesis.

The experiment aimed at determining the quality of drinking water through the examination and comparison of the level of contamination in tap water, Fiji bottled water and Dasani bottled water. Through the experiment the researcher wanted to prove that bottled water is worth the cost. The methods used included the ammonia test strip experiment, the chloride test strip experiment, the 4 in 1 test strip experiment, the phosphate test strip experiment and the iron test strip experiment, which were simultaneously performed for the three water samples. The results indicated that bottled water tend to be less contaminated as compared to tap water, thus making them safe for drinking and effective for preventing waterborne diseases. the Dasani water had the lowest level of contamination, followed by the Fiji water, with the tap water having the highest level of water contamination.

The water quality of the U-High creek is excellent, however not all water is excellent like U-Highs creek. One-way people could pollute the water is when farmers put fertilizer on their plants. When it rains it flows into rivers and the chemicals nitrogen and phosphorus can cause plants like algae to grow faster and may cover the sea floor. This is bad for the plants under algae because they will not be able photosynthesize. Also when the algae are broken down the bacteria quickly multiply using all of the oxygen in the water which may kill other animals. (Lenntech 1998) Another way people can pollute the creek is after heavy rainfall the drainage systems overflow into rivers or lakes which pollutes the water with feces and urine, this may

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.

Increasing water temperatures decrease the amount of phytoplankton, which is what shrimp eat. As the water temperature increases it takes a ripple effect into the marine ecosystem, phytoplankton decrease in numbers, shrimp decline in numbers, those that prey off of shrimp decline and so on (Trotter). This then leads species to migrate to stable habitats, but survival of the fittest takes into place and large amounts die off in the process.

Experiments were done on the water quality and the contamination of groundwater. First, I observed the effects that different pollutants had on groundwater. I predicted that the experiments with the oil and vinegar would create the most contaminations to the water. When the laundry detergent were mixed with the groundwater, it created a light green color with a pleasant smell. The second water treatment experiment were about filtering techniques to remove contaminants from water. I predicted to drain the water by removing all the contaminants

Another goal was to track changes in water quality, especially the expected reduction of nutrient inputs from the watershed from the installation and improvement of collection and treatment infrastructure in the County. Objectives of the AMP, in accordance with the ACJ are as follows:

The purpose of the succeeding article is to weigh the opinions of two different sources concerning the topic of water pollution. Many people neglect the water issue due to the fact that it does not necessarily pertain to them. However, there are several complications that should definitely be brought to awareness among the public. This article uses two sources to explain why and how the activities of humans contributes to the poisoning of the world’s water supply, and how the articles use argumentative such as ethos, logos, and pathos to justify and compare their position.

In order to assess the water quality of Farm Pond the class collected a variety of data. The class

Fish, insects, phytoplankton, and zooplankton are all examples of water species that survive in favored temperature ranges. These species have adapted to the water weather condition so well that, if the temperature gets too above or too below their preferred range, they will slowly begin to decrease in numbers, until they are in extinction or until there are completely none left of the species. The extinction of these species will only create a ripple effect up the food chain, causing extinction of other freshwater species. Plankton is one of the most rich life forms, the food it produces makes up the base layer of the global food chain (Helen, 2015). The decrease of phytoplankton can lead to extinction of many other species. Less plankton makes for less food for fish and so

The environment plays a large role in the number of nutrients and other materials which are implemented into the water surrounding. If the environment is highly populated with more human traffic, then the water would be less healthy as the environment would not be as pristine. The environment with a more natural feel, more nutrients, would tend to have a healthier water system because of minerals would not be polluting to the surrounding area as certain climates are. The water quality affecting aquatic species is “important for maintaining fish health and reducing stress throughout transport as well as proper tempering into the receiving water” (Harmon). If there are any changes in the water quality the species in the area could be drastically affected which has a chain reaction back to humans as most of these species are low in the food chain and are required to collect the fish, we do today for

With water bodies that are near agricultural areas, with fluctuations of the levels of nitrates and phosphates that are introduced to the water bodies, the dissolved oxygen levels are affected. Turbidity is also another important measurement of water quality as it affects not only the pH levels of the water but also the temperature of the water. Turbidity itself measures the light refractiveness found in water used to quantify the quality of water (Mann et al.,

This can cause harm to animals such as amphibians and fish and other water based life. Some affects on aquatic life when water of a higher temperature is introduced is the de-oxygenation of water this is because when water is heated the level of dissolved oxygen in that water decreases, this make the water harder for fish to breathe in. It may also cause an increase in the metabolic rate of aquatic life forms, which would cause the animals to eat more food in a shorter time period and may result in a shortage of resources for the organisms of the surrounding area. Finally many aquatic species have a hard time successfully reproducing at higher temperatures. The effects on water-based life forms when cooler water is introduced are also detrimental to the ecosystem. Such as altering the native species found in an ecosystem that is used to warmer waters this can result in entire native fish species being eliminated and other organisms which are more accustomed to the cooler water over populating and destroying the natural food
