Case Study On Water Pollution

Codi noticed an irregularity in the river when her biology students and herself tested the pH of the river and found that it was very acidic. The Environmental

The chemical characteristics observed and documented were pH, temperature, phosphate, nitrate, turbidity, and dissolved oxygen. Each of these chemical levels were documented and found differently. Most were found using a kit or a device. The numbers found, would tell us how polluted the stream was and how much nutrients were in the water. Each chemical has a scale for telling what a good level is and what a bad level is. If an excess amount of nutrients was found in the water, algae could be formed. When algae is formed it blocks sunlight from shining into the water, which creates dead zones. This is called eutrophication. A dead zone is an area where there is no life. This can cause major problems like population issues and more. If the algae continues to grow in the river, the whole body of water can die out, and people as well as other organisms are very dependent on the Susquehanna. While on the river though, there was an absence of algae, so sunlight is able to get through the water, which is very good.

Comprising over seventy percent of the Earth's surface, water is undeniably the most valuable natural resource. Life on Earth would be non-existent without water because it is essential for everything on our planet to grow. The human body is composed of 50-80% water. Blood and muscles contain significant amounts, and approximately 95% of the brain is water. All body systems and organs need water to function properly, and will shut down without it. Most of the chemical reactions that take place in our body need water as their medium. We can live without food for a few weeks, but can survive only a few days without water. It's essential because unlike other nutrients, water isn't stored in the body. Typically, everyday, we lose around 10

Please briefly describe the different types of water pollution mentioned throughout the "Poisoned Waters" video. Fertilizers, Nitrogen and Phosphorous caused algae which poisoned the waters. It caused a dead zone. The farmers who own chickens was allowing the manure to pollute the water. The humans race is all responsible as we pollute our water by throwing garbage into it. Soap, household cleaning agents, toothpaste, and other plastic, lubricant and fuels are all poisoning our water.

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.

The first piece of evidence supporting this statement is a water quality index of 48. The 7 pollution sensitive organisms in the creek are worth three points each on the water quality index, plus the 10 moderately tolerant organisms each 2 points and the 7 tolerant organisms each 1 point add up to get the 48 water quality index. The water quality level is considered excellent if it is 23 or above. The water quality in the U-High creek is more than twice that. There were many different types of organisms found in the creek including 7 pollution intolerant micro invertebrates. The total number of organisms including the 88 pollution intolerant Caddis fly larvae point to a low pollution level in the creek. The 10 moderately tolerant micro invertebrates also point to low polluted creek. There were also a high number of midges and aquatic worms. The water in the creek was also very clear and did not have a smell. There were many small fish and plants growing in and around it concluding a low pollution level in the

Watershed protection is a means of protecting a lake, river, or stream by managing the entire watershed that drains into it. Clean, healthy watersheds depend on an informed public to make the right decisions when it comes to the environment and actions made by the community.

"A watershed is an area or ridge of land that separates waters flowing to different rivers, basins, or seas."

What is a watershed? A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. You think every creek is the same but in reality they’re not. In this essay we are comparing San Mateo and San Juan creek.

A watershed is a land area that drains rain and other water into creeks, rivers, lakes, oceans, etc.

The Upper Wabash River faces a vast majority of issues that affect the quality of the watershed. The watershed has long been used for agricultural purposes that cause stress on the watershed. Through various point source and non-point source pollution various water systems have been affected with some being even impaired.

The pollutants affecting water quality is a major issue affecting every community on a global scale. Whether individuals suffer from lack of

The water quality was excellent at the UHS creek, but not all creeks or streams have a great water quality. The current water quality index for the UHS creek is 42. Some human impacts to keep this water clean consists of a clean environment by not littering, picking up any garbage by/in the creek, or making sure only pure water is flowing through the stream and not any sewer water. To prove the point that some creeks don’t have a great quality, but actually end up have an excellent water quality like the UHS creek. Some observations looking at the UHS creek for the first time were; the plants appeared dead, garbage on the banks of the rivers and in the water, and the creek smelled bad. Even though these seem like bad observations not all observations

Stream flow is discharge; it is the measurement of a volume of water that travels past a specific point in a fixed duration (United States Environmental Protection Agency, 2012). Discharge alters depending on the weather, month and nearby events such as erosion (United States Environmental Protection Agency, 2012). It is important because it influences the water quality, habitat and organism availability (United States Environmental Protection Agency, 2012). Large discharges indicate a swift flow of large amounts of water, thus spilt pollutants (i.e. from runoff) are heavily diluted and will cause little harm to the stream (United States Environmental Protection Agency, 2012). On the other hand, stream velocity is the stream’s speed, and like discharge, it also determines the streams living conditions because high velocity allows sediments to stay suspended without disturbing bottom habitats (United States Environmental Protection Agency, 2012). Unfortunately, both stream velocity and discharge were slow when analysed. This may be because of the rainstorm on Wednesday, March 29th that caused the stream to drain rapidly and cause the stream to fall the day after (United States Environmental Protection Agency,

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.
