Research Aspects Of Water Quality

Water is probably the most important resource we as people have. Humans can survive without food for several weeks, but without water we would die in less than a week. On a slightly less dramatic note, millions of liters of water are needed every day worldwide for washing, irrigating crops, and cooling industrial processes, not to mention leisure industries such as swimming pools and water-sports centers. Despite our dependence on water, we use it as a dumping ground for all sorts of waste, and do very little to protect the water supplies we have.

Water quality is based upon a set of standards that describe the kinds and amounts of minerals and other substances that may be present in the water.

In the North Queensland Resource Planning and Development, the consumption of high quality drinking water has become a major issue. Due to the limited supply of fresh water in other states and South East Queensland, a major re-education of the public on water usage has occurred. The demand for water has increased within the Cairns region, so to provide the extra water needed for the Far North community, the government is considering tapping into the Mulgrave Aquifer. On further investigation, it was seen that this process would be quite expensive to go ahead with. A more viable option would be to source the water directly from the Mulgrave River. The purpose of this report is to analyse and discuss the water quality of four locations along the Mulgrave River.

The water quality of the U-High creek was excellent, but not all bodies of water have excellent water quality. Humans can pollute water by farmers putting pesticides and fertilizers on their crops. Putting fertilizers on the crops pollutes water, because when it rains the pesticides and fertilizers get washed off and carried into the water, and this adds nitrates and phosphates to the water which is called eutrophication, and it increases the amount of algae in the water. When there is an excess amount of algae in water, there is an excess amount of bacteria the uses up most of the oxygen which kills plants and animals. (River Quality and Pollution,2016) The second way humans pollute water is when it rains there is runoff, and all of the pollution on the ground get carried into the water. Runoff is when it rains the soil and other things get carried to other places. An example of runoff is when there is a heavy rain, the soil sitting on the sides of a hill loosen and slide down the hill toward the bottom causing a buildup at the bottom of the hill.

The quality of water in the U-High creek was excellent. In other water areas the water quality might not be the same. There are different ways humans can pollute the water. Runoff is a good way to pollute the waterways. When you litter on the ground rainfall will pick up the trash and take it to the water. This then makes the water quality go down.(Howard Perlman, May 2, 2016) Another way humans can pollute is with pesticides from farmers. They spray these pesticides on the plants and then rainfall takes the pesticides from the plants and brings it to the water. This then makes the nitrogen and phosphate levels go up and bring the amount of algae in the water. Thus bringing the amount of oxygen in the water down.(Arthur S. Brooks, 2016) Next

Natural freshwater is not completely pure. It contains solute dissolved from erosion of minerals and dissolved gases from the atmosphere 5. Calcium, Ca2+, and magnesium, Mg2+, are the most common and abundant solutes found in natural waters. This is due to the presence of natural minerals such as limestone and dolomite 6. The hardness of water is defined as the concentration of dissolved mineral cations, mainly calcium and magnesium, in water. Therefore, by this definition, a hard water contains high concentration of solutes and a soft water contains low concentration of solutes 5. The following table shows the water hardness category according to the United States Department of Interior and the Water Quality Association 7.

It has been estimated that the state's capital will require an additional 150 billion litres of water

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 safety of drinking water is an ongoing concern within the global society. No doubt, the quality of drinking water is the most essential factor. So let’s take a closer look on what is important when we talk about drinking water quality.

Almost every experiment had good results. The only to bad results were the pH- using strips and the turbidity. The pH - using trips was a 4 but doing the pH - using tablets had a 7. So it can go either way. Turbidity was 20 but that isn’t that high. The DO was 4ppm and that is almost perfect. That means that it has plants, but not a lot of them. The temperature of the pond was not cold and not warm. The temperature varies though throughout the seasons. There were 0 ppm results for the nitrates. That is very good. It doesn’t increase the plant growth but also doesn’t decrease the plant growth. The ammonia levels were also 0ppm. That means that the insects and animals don’t get sick by drinking the water or swimming in it. There were many bioindicators in the pond. There were water striders, tadpoles, grass, flowers, algae, gnats, and cat tails. The Voyager pond is very healthy and it should stay

When talking about water quality, many of the given factors can change what you’re given to drink. Nitrates, phosphates, dissolved oxygen, turbidity, temperature, and pH levels all affect the drinking water quality.

Background: First, we must take a look at the reason and history behind water quality and explore creditable information that involves testing and understanding of water quality. Water quality is the essential element to life and living creatures. It influences the structure of our environment, welfare and other living organism who lives on earth. The Author of explains that If our society doesn’t observe the changes and find a solution, the cycle of life will be offset, this means that everything is affected if water quality is ignored, the whole ecosystem will shift. Water quality is managed and evaluate for levels of bacteria. In a science. exploring studies and test that can allow us to conclude the changes as well as the effects. It’s very crucial for society to find solutions and strategies

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

Water has been very essential to us as humans since mankind has existed. Water is essential for humans because we need it in order to survive. In many cultures water is viewed as having restorative powers and is very important to these kinds of people not just biologically but spiritually as well. However, as humans have progressed their technological advances, water has become an afterthought. Water pollution has become a very big problem within the last century and the issue is only getting worse. As time has gone on mankind’s philosophy about the world’s waters changed and water pollution has gotten worse and come from many sources throughout the years.

Many of the researches on the WQI has been dedicated to surface water especially for rivers. There have been some efforts to adapt WQI for groundwater assessment. The developed indices of groundwater quality are very similar to WQIs. The differences among them are in parameter selection. In the first attempts to develop WQI for groundwater, Tiwari and Mishra (1985) utilize the WQI for ranking groundwater for drinking purposes. Over the years, many researchers have used this procedure for groundwater quality assessment (Ketata et al., 2011; Ramachandramoorthy et al., 2010; Srivastava et al., 2011). Many authors have used a different procedure to develop groundwater quality indices (Ramakrishnaiah et al., 2009; Banoeng-Yakubo et al., 2009; Giri et al., 2010; Banerjee and Srivastava, 2011).
