The water quality of the U-High Creek was identified as excellent, but not all bodies of water have excellent water quality. Humans can pollute water in many ways, and make it unsuitable for organisms living in the water. One way humans can pollute water is when farmers put pesticides and fertilizers on their crops, which contain harmful chemicals like phosphates and Nitrates. When it rains, the pesticides get washed away through the soil and end up in rivers, streams, and creeks, therefore…

the dye extracted from samples of magnetic bentonite clay and of charcoal through filtration. From the data collected in this experiment, it was found that charcoal was a more effective alternative to use as an absorbing agent in rivers to clear the water of harmful PAHs. INTRODUCTION…
The goal of this lab was to determine the heat of fusion of ice (or water). According to Chem.Libretexts.org, Heat of fusion is where solids are heated to a specific heat capacity (The number of heat units needed to raise the temperature by 1 degrees) in order to break the bonds that are keeping them attached, which is called the attractive force. This lab also dealt with the concept of the direction in which a temperature follow. According to chemistryexplained.com, temperature is the measure…
fossil fuels because it doesn’t allow gasses to escape out into the atmosphere. With the air heating up and getting warmer, the water temperatures are heating up to, which is very bad for trout who have evolved to only live in cool water; trout are uncomfortable in water above about 20°C. When water temperature heats up it doesn’t allow oxygen to dissolve into the water like it should,…

Rivers generally start as a trickle of water high in hills or mountains. Some come from rainwater or melting snow. Most appear from underground watercourses, shaped after rain or snow seeps into the ground then fizzes back to the exterior.…
How Can We Know Fracking and Drilling are Safe? Fracking is injecting liquid, filled with chemicals and water, into the earth to reach oil or gas to then extract it. Fracking is controversial due to the fact that the earth, humans, and water supply is harmed in the process. Research has shown that fracking is not necessarily a safe process, but there are safer ways to complete the process. Toxicological Science can lessen the casualties of or effects to human health and the environment, but…
large volume of water along with sand and chemicals 3. A result of this process is contamination of groundwater; this is raising concerns for many environmentalists and the Environmental Protection Agency because it is harmful for public health3. I believe that fracking should be continued because it is beneficially to the economy, and that there is nothing wrong with New Jersey storing natural gases and having pipes from the Marcellus Shale to here. I also believe that more laws should be…
Water is a prevalent feature of Earth, in which about 70 percent of it covers the entire planet’s surface. In addition, water is vital to the development of life and the maintenance of many living organisms, including humans. The waters are filled with numerous aquatic species, including different kinds of fishes, turtles, crabs, corals, and other large mammals. One of the problems many marine animals face is the pollution invading their homes due to the carelessness and ignorance of human…
