Water systems can have a huge impact on humans. Depending on a water system, fresh water could more or less difficult to access. Certain eco-systems can be shaped differently with different water systems. This could affect where we fish, farm or hunt. Water systems define how water, the most important item for us, is used and moved. Water systems are mainly associated with water and we need that water.
Water systems can affect climate and precipitation. Whether positive or negative it definitely does. Here are a few ways!
Large bodies of water: Oceans, seas, and large lakes affect the climate of an area. Water heats and cools more slowly than land. So during summer, coastal regions will stay cooler and in winter warmer. This creates a balance.
Moisture: If an area has more moist air, than it is most likely to rain there more often.
Water testing and processing is so important because water is very needed and very vulnerable. Water can get contaminated so easily, and if it is, our health is at risk. Various illnesses can spread, it can affect our ecosystems, etc… As much as we need it, we still need to be careful, as it can bring us a totally opposite effect.
There are many standards to assess water quality with. However, the most common standard used, relates to the health of ecosystems, human contact safety and drinking safety. Here are some ways we test water!
Turbidity: Sediment makes water turbid or unclear. Clear water is of better quality. This is tested simply by looking at the water.
Temperature: Warm water has less dissolved oxygen than cold water. If the water does not contain enough oxygen, aquatic animals may die. This can be tested with a thermometer.
Acidity: Water becomes acidic if it contains certain dissolved chemicals, such as sulfuric acid or nitric acid. Most fish cannot reproduce in acidic water. This can be tested with an indicator that turns into different colours in acidic and basic solutions.
Everyday we use water just by turning on a tap, but do you ever wonder how? I mean the water does come from lakes or rivers, but who knows how clean they actually are. Well, here are some steps people take, to make sure the water is fresh and clean to use!
Step 1: Removing large objects. A metal screen covers the end of a pipe that drains water from its source.
Step 2: Water enters a large tank where alum is added. The alum is stirred and forms small, sticky lumps that attract most of the solid waste floating in the water. This waste is called floe.
Step 3: The water and floe enter a settling tank. The water flows slowly to allow the floe to settle at the bottom of tank.
Step 4: The partially cleaned water from the top of the tank moves through a sand Andy charcoal filter.
Step 5: Chlorine or ozone may be added to the water to kill microorganisms.
Step 6: The treated water is stored in sealed containers, ready for use.
Water is used everyday. From drinking to washing, or even for entertainment, water is a very needed item. Without water there would be no life, its the very base of all organisms. It would be impossible for humans to live without water. No water means no plants, no plants means no animals and so on. Water cannot be replaced and should be used wisely.
Some examples of water systems found in Canada are its bodies of water (ex. Great lakes, Rivers, etc…), water sanitation systems, water supply systems, etc….
Well first off, what is a system? Its an organised scheme or method. Now, what’s water? For time’s sake, let’s just call it a “needed liquid”. Now combined, its an organised scheme or method applied to water. Which, in other words mean a system (method/way) in which water (a needed liquid) is the main ingredient used in that system for a certain purpose.
By definition, water is a transparent, colorless, odorless liquid that forms the seas, lakes, rivers and rain. It is also the basis of the fluids of living organisms.
