How can human and natural factors can change the water table?

The water table consists of precipitation. Some factors that impact the water table are:
Land use (Human activity): For example, agriculture land use is the land farmers use for agriculture, as that is the purpose they give to that land. Farmers often use chemicals such as herbicides and pesticides to kill any unwanted plants or animals that try to get near any crops and affect them. The chemicals that come from pesticides can enter the soil, causing the soil to be contaminated from its chemicals. This may cause the contaminants to go down, reach the water table, and affect the water table, which is water pollution.This changes the water table by affecting it.
Irrigation (Human activity): When crops are watered,the water  drains through the soil. This means that some of the water can even go down enough to reach the water table, and get into it too. Over time, as more and more crops are watered more and more times, the water table will rise, causing an increase in the water. This changes the water table by increasing the amount of water.

Precipitation (Natural activity): Precipitation such as rain can drain through the land/soil, and reach the water table. Then, the water gets into the water table, which increases the amount of water in the water table, as water table is mostly water that comes from precipitation.

Droughts (Natural activity): Natural disasters that cause dry land such as Droughts can affect the water table. Droughts occur when an area of land lacks adequate precipitation. This can cause the water table to fall, by decreasing the amount of water that is present in it.

Groundwater commonly contains less contamination than surface water because the rocks in the bedrock tend to act as a filter to remove some contaminants. One fact about groundwater is that groundwater is usually clean, but it can still be contaminated from the chemicals used for underground mining, such as gasoline. If gasoline gets into the groundwater, the groundwater will become unsafe and unfit for human use. Road salts are another risk factor for groundwater contamination. When it rains, those kind of chemicals can drain into the ground and eventually go down enough, making its way into the ground water. Road salts are used in the winter to melt ice on roads. When the ice melts, the salt gets washed off the roads and eventually ends up in the water. One more risk factor towards groundwater contamination are landfills. When landfills are buried underground (not all the way down to the groundwater), there is also a bottom layer that is meant to prevent contaminants from getting into the water. If there is no layer or the layer is cracked, contaminants from the landfill can get into the groundwater through the cracks or straight through if the layer is missing. The rocks only remove some contaminants, which means that there are still more contaminants in that water. Therefore, groundwater has a greater risk towards contamination and unfit use than surface water.

One way of how I am currently getting water is from Lake Ontario, which is a lake. Lakes are also known as the surface water. I would like to get my water from surface water, because it is best from the other type, which is groundwater. Currently, the surface water I am using is properly cleaned using the water treatment process at water treatment plant facilities. Groundwater has a greater risk towards contamination. For example, groundwater contamination commonly occurs when environmentally harmful things such as gasoline get into the groundwater due to underground mining activities. That causes the water to become unsafe and unfit for human use. This is because it may be hard to remove the gasoline, since it is toxic.

In peel region, we get our water primarily from Lake Ontario. We also get our water from a regionally-owned well, and from a private well.The Region of Peel owns two large water treatment facilities - Lakeview and Lorne Park - on the shore of Lake Ontario. Lakeview and Lorne park are two facilities where our water is treated, since those are the two facilities the region of peel owns and since we belong in the region of peel.

A watershed is an area of land in which all the water drains into the same body of water. Watersheds also get filled again and again with precipitation or melted ice from high land to low land, due to gravity. In this case, water management would be watershed management which is the process of achieving land use practices to protect and improve the quality of the water and other natural resources within a watershed by managing the use of that land and land resources extensively.

People throwing down oil or chemicals into their drain or into the ground, as that oil can go all the way down and join and affect the whole area's wastewater, and create a mess. The pollutants from those chemicals can pollute the wastewater that does to the wastewater treatment facility, and makes a bigger mess.

Some people don't turn the tap off while brushing. That clean water that is left on would go down into the drain without being used, and join the rest of the wastewater which is about to be treated. That clean water would get dirty with the wastewater. The water that went down without being used was actually wasted, as it was cleaned carefully for people to use. If that water goes into the drain without being used, then it would be as if there was no point in cleaning that water.

There is a water treatment process that gets your water to your tap from lakes or rivers. This process ensures you have safe and clean water to use throughout the day. There are eight steps in the procedure:

Intake: Water is taken from rivers or lakes for treatment. The water is flown through a metal screen, which is at the end of the pipe. This is so that the unwanted big parts that are in the water (Sticks, leaves, garbage) can be removed from the water.

Addition of chemicals: The water flows through and goes inside a large tank where a chemical called "Alum" is added.
Coagulation and flocculation:  The chemical is dissolved in the water so that as a result, lumps of the chemical would be formed that would help absorb any leftover waste in the water.(e.g. sand, sticks, e.t.c.). The combined mixture of the Alum and the waste is called "Floc".
Sedimentation: After, the water and the floc enter a tank which is specifically for allowing the floc to settle at the bottom of the tank o that it can be separated from the water.
Filtration: After sedimentation, the water has been partially cleaned, as the floc has been separated and removed from the water. Filtration cleanses the water so that it is fully clean, clear, and odorless at the end. The water which was at the top of the settling tank moves through filters. The filters are made of layers of sand and gravel. This type of filter will remove any leftover waste or small pieces of floc that weren't removed before. This ensures that most of the waste or all of it has been removed and the water is clean.
Disinfection: Chemicals such as chlorine and ozone are added to the cleansed water so that in case if there is any bacteria or other organisms that can make people ill if used, the chemicals would kill those organisms.
Storage/your neighborhood: The water that has been treated is stored in big tanks, as it is ready for use. The water from the storage tanks would be the water people get for their homes from the water tank, as the water tanks stores water that is for the neighborhood. Water flows from the big tanks through underground pipes and get to pumping stations so that the water gets pumped through the pipes and into houses for families to use.
