Watersheds are also known as drainage basins and it is an area of land on which runoff drains into a certain outlet for example a river or another water body. Drainage basins are quite important to water management as they give you all the aspects on where to stop pollution so our water stays cleaner. For us river basins are very important as they provide us with freshwater if there is any pollution in the river basin the water management plans to manage it. Watersheds provide nearing urban areas with a water supply and water management planning enforces action to protect the watersheds. There are also laws to protect drainage basins and water management is what protects the watersheds and keeps them intact so we make use of our natural resources without harming them and the environment providing us with it.

Water is the most vital ingredient for our body and we can only live a few days without water. We find water surrounding us in many different forms whether it be a small water body like a river or a huge water body like an ocean or a sea and we use it in almost every activity we engage in. For example when we're cooking, personal hygiene, cleaning the dishes, laundry, almost anything you could think of even recreational activities such as swimming. Did you know 70% of Earth is water and most of the human body is also composed of water. 97% of water on Earth is salt water and only 3% of water on Earth is freshwater and even 2% of that freshwater is found in glaciers and icebergs leaving us an accessible 1% of water to use in our daily life. Water supply can not vanish as long as the water cycle goes on

Impact On Local Water Quality And The Water Table 

# data[].attributes.body
Humans have a huge impact on everything especially when it comes to the environment however it almost always ends up being negative and there's no difference in this case. We are always polluting the environment and we don't end up caring that we're even polluting the water that we can't live without. We throw plastic and other waste into our lakes and water bodies but not just that also our industries dispose their harmful contaminants and toxic waste into our water. In addition, farmers use pesticides and herbicides on their land and when there's any precipitation the surface run off travels through the cracks in the soil and gets tot he ground water as well it flows into the streams and other water bodies. This makes the water sources polluted especially if there are any accidental oil spills in a water source it isn't able to be treated and not safe to be used which ruins a water source. The quality can also become extremely poor because of some of the pollutants found in the water. For the water table the natural impact is that it will seasonally shift by itself. The impact we cause is by using harmful fertilizers and herbicides which seep into the soil through surface runoff and contaminate the ground water. Other than that, taking too much groundwater out of the aquifer could have a hugely negative impact on the water table

Locally we receive water from our utilities and from water sources for us we leave near the Great Lakes so that is one of the most accessible sources. Water sources are surface water and ground water which is acquired from aquifers. Surface waters include lakes and rivers as they are freshwater sources and we only use freshwater for our needs. My preference would be water from water source that isn't polluted I'd rather a water source from a place far from people as people throw a lot of pollutants in water. Especially I wouldn't want water from a water body which people transport by as oil spills are a huge issue and water contaminated by oil can't be treated to be consumable or safe for use. My preference between surface water and ground water would definitely be ground water as it's definitely less polluted than surface water. As well groundwater needs less treatment most of the time.

Water Treatment System

# data[].attributes.body
We use water in our daily life repetitively whether it be to drink water or to clean something. What if that water weren't clean. We are privileged to be able to access clean water but is water just given to us by our utilities fresh out of the water sources. No it isn't as water is a solvent and everything is soluble in water and harmful and dangerous pollutants could have dissolved in the water or microorganisms such as harmful bacteria which is not to be consumed. Water treatment is the process in which water is taken from water sources which includes surface water and groundwater obtained from aquifers and they treat it in a water treatment plant to assure it's safe for people to consume.

Water treatment involves about 7 major steps to secure the water is of quality to consume and that it meets water quality levels given by the government. Those seven steps are intake, chemical addition, coagulation and flocculation, sedimentation, filtration, disinfection, storage. The following are descriptions of each step:
1. Intake: In this step the water flows through a metal screen which makes sure all the huge objects such as steel or stick objects don't enter with the water.
2. Chemical Addition: In this step alum (aluminium sulfate) is stirred into the water and it creates sticky lumps which attracts the waste solids in the water . It improves the taste, odor, kills germs, and settles the solids that remain in the water.
3. Coagulation and Flocculation: This makes the alum from the previous step cling to another material which is put in the water and this forms bigger particles called floc.
4. Sedimentation: In this step the water and the floc flow into the sedimentation basin and the floc sinks into the bottom and leaves the water.
5. Filtration: Water flows into the filters which are built of sand and gravel from the sedimentation basin. The filters remove any of parts of the floc that is remaining.
6. Disinfection: A minimal amount of chlorine is put into the water that completely kills any germs remaining.
7. Storage: Water is put into a reservoir or a tank which is known as a clear well and when the water is in that it is given time for the chlorine to completely mix with the water until disinfection occurs. After all these steps water flows into the distribution system and we receive our safe and clean water.
