All living organism depends on water and its quality. Human activities and the ways we use our river and streams and the land around affect the quality of the water we drink, cook with, and use for recreational opportunities (Erwin, Hamilton, 2002). It also affect the health and diversity of aquatic plants and animals and the beauty of our rivers and streams (Erwin, Hamilton, 2002). Many rivers and streams are significantly polluted all around the world (Lenntech, 2016). Industries and cities, agricultural and domestic activities are three major sources of pollution that are usually concentrated along the rivers(Lenntech, 2016). According to the Environmental Protection Agency, the main sources of water pollution are industrial waste with harmful …show more content…
Water quality testing and monitoring is important for our environment. Water quality parameters such as pH, turbidity, conductivity and phosphate levels are important measures that can affect the quality of water in our environment. The pH measure how acidic or basic the river water is on a scale of 0-14 (Behar, 1997). According to the Environmental Protection Agency website, the normal level of pH for river water is around …show more content…
We obtain water samples from both the Middle Patuxent River and the Inner harbor in Baltimore.The Inner Harbor in Baltimore seemed heavily polluted based on our observations. There were litter like plastic, paper, rubbish around the deck and in most areas, and some were floating on the water surface. The Middle Patuxent River doesn’t seemed polluted. It seemed natural and It was surrounded by woods, trees and rocks. It had green vegetation around it and the trees seemed to provide a good shade. Also the water looks clear. From each location, we collected 2 separate water samples about fifty yards away from each other in order to obtain more reliable results and limit variability. The samples were gathered the same day and at the same time to limit error in the testing due to changes in the weather. An independent variable is the variable that can be controlled and manipulated. It is what we think will affect the dependent variable (Readel,2000). Our independent variable will be the water samples taken from each distance at the Inner Harbor in Baltimore and the Middle Patuxent River. A dependent variable is what you measure in the experiment. It is what we think will be affected during
Water pollution is a very serious problem as it affects one of the most essential ingredients to our very livelihood. The earth is covered in water, in fact about 70% of the Earth is covered in water, only
Whether we want to believe it or not water pollution is one of the world’s l...
For this whole project on the Conodoguinet creek we are trying to figure out whether or not the creek is polluted. Therefore in this project we had to form a hypothesis. My hypothesis was,If we test the Conodoguinet Creek for signs of acid rain, eutrophication or other types of pollution, at the instant when we perform the experiments we'll know whether or not the creek is polluted. Eutrophication, which is excessive richness in nutrients in a body of water due to runoff, causes a dense growth of plant life and death of macroinvertebrates due to lack of oxygen, has been a problem in the Conodoguinet Creek. In conjunction with Eutrophication, Acid rain which is, a rainfall that damages or harms the water environment has also been a key factor
The purpose of this research is to determine the relationship between pollution and water while the physical properties of water are held fixed. I am going to compare the “polluted” water with the purified water and see if it changed in anyway. For this experiment, I’m going to use water containing sand and oil to get “polluted” water. Also, I am going to use two methods of separation of substances, distillation to remove the oil, and filtration to remove the sand. Then I am going to use activated charcoal to remove any dissolved substances in the water. After that the water is purified.
Water is essential in our everyday life. Water is one of the most important substances on earth. All plants and animals utilize water to survive. Therefore it is vital that there be clean water for our communities to utilize to survive as a whole. Unfortunately because of different determinants our source of water are not always safe to use. We happen to have to deal with contamination of drinking water. Contamination of fresh water used for household needs, including pollution of oceans, rivers, lakes and reservoirs. There are categories of the different contaminants that exist such as Physical contaminants, Chemical contaminants, Biological contaminants, and radiological contaminants ("Types of Drinking Water Contaminants | Drinking Water
Living in a world that is roughly 70% water, and all living creatures found on this planet depend on this resource whether directly or indirectly, making water quality an important topic and vital to sustain our world of cycles. “Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands.” (Bai V, 2009) With most of our water on this planet made of salt water and our constant damage towards the remaining water that can be consumed by humans is diminishing with improper distribution on a global scale. If our greed comes before companionship, and our quality of life is more important than pollution, then our future generations to come will be born into a world of chaos, and a scarce of a basic human necessity.
The pH of the water can have a great impact on aquatic life and the ecosystem if it has sudden shifts. The pH was first checked with the pH paper resulting with an average of three trials resulting in a 7.1 reading. Next the pH was read with the pH meter, the result of the three trials yielded an average of 8.31 and the pH on the day of collection was 7.12. The 7.1 reading of the pH paper fell more closely to the sample day pH, with a range of 0.4. On the other hand the pH meter recorded the pH with a range of only .05 which is much closer and the 8.31 average more closely relates to previous data on the Chip-A-Waters River. The day of the sample selection there was rain that could have had acidity that made the sample day water more acidic than usual, and the pH paper readings could have been in error due to old pH paper and limitation of available reading range and significant figures. Though on the pH meter there was a found uncertainty of .19. When the buffer 7.0 pH solution was tested with the meter it read at a 7.19 pH. Both readings though vastly different fall between the normal range of 5.5-8.5
Water Quality is a way used to measure the quality of water in an area based on sampling. The water quality in the UHS creek was excellent. Humans can negatively impact water quality by dumping waste from factories in to rivers. As many industries are located along rivers, it makes them a convenient place for them to dump their waste, polluting the water. Another way humans can effect water quality is from storm water runoff. When it rains, the water travels down into ditches which can lead to streams, and on the way down the water picks up harmful chemicals in our cities that make their way into food chains.
The Earth’s surface is covered by over two-thirds of water. With half of the world being covered by water; pollution in the water is a very big crisis that can actually be reduced to some extent. Water pollution is a human problem because it seems to be a recent development that started round the end of the 19th century. Scientists say that “humans have limits with an estimated 7 billion people on the planet, and pollution is a sign of exceeded pollution. According to the WWF (World Wildlife Fund) pollution is a serious problem. “Pollution from toxic chemicals threatens life on this planet. Every ocean and every continent, from the tropics to the once-pristine polar regions, is contaminated." Now that we know how serious it is, let’s talk about what pollution is, what causes it, the effects, and how we can help.
A single water drop traveling from any river to any ocean is influenced with more than one hundred toxic chemicals and thousands of industrial pollutants. This is what people call water pollution, occurring in any state, country or continent. Unfortunately, throughout the centuries, water pollution has been an ongoing problem, mainly caused by the release of industrial toxins and chemicals. People around the world believe that plastic and metal make up the vast majority of this issue, but as years have come and gone, the quantity of chemicals released by small and large facilities are now the leading cause of water pollution. Although industries need to release waste somewhere, they should avoid putting it in waterways because it impacts the
In this lab we will be testing bodies of freshwater. We will be determining the quality of the water based on multiple factors including nitrates, phosphates, pH levels, and dissolved oxygen levels. All of these factors must be in appropriate ranges for the ecosystem to be healthy.
Water Pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.

The parameters of water quality are determined by how the water is going to be used. “Most of the parameters affirmed are focused on treating it for human consumption, industrial use and environment. The main water quality parameters that are measured in natural water are
Water pollution is also a major thing in the world because almost 60% of it is fishes. It occurs due to several factors; the industrial waste dumped into the rivers and other water body’s cause am imbalance in the water leading to its severe contamination and deaths. And the infamous Global warming is the emission of greenhouse gases particularly CO2 is leading to global warming.
