On the 24th of July, we went to Little River and Yeates Pond in order to investigate the level of nutrients present. We went to three sites to test, and we checked the pH (the level of acidity of the water), coliform (the sanity of the water), turbidity (the visibility through the water), dissolved oxygen (the amount of oxygen present in the water), nitrate, and phosphate levels. At these locations our results were good with the exception of nitrates and phosphates (although that could have been because of the heavy rainfall the day before); they were within the legal range specified by nature laws. While testing, we learned that the presence of certain nutrients allows some aquatic life to thrive more easily than others. That is one of the main reasons that creatures live where they do. Another factor that affects the life that can survive in the water is dissolved oxygen. Since almost all aquatic life uses oxygen, the amount that is available will directly impact what lives there based on how much oxygen they need. It is important to test the water because it is very easy for fertilizers and runoff from the land to drain into it. Due to how easy it is for pollutants to enter the water it needs to be tested often. The quality of the water affects the health of surrounding plant and animal life, and those lives could easily be disrupted by a sudden addition of a foreign substance into the drinking water. An unhealthy water source can poison the surrounding wildlife, as well as be unpleasant to look at. Yet it is quite easy for that to happen, especially with Combined Sewage Overflows dumping waste into it. And because of that, consistent water testing is necessary for a clean, healthy, environment.
