  4. Lowest PH- 6.80- 4 locations
  5. Highest Acid- 8.00- Caribbean-Tap
  6. Lowest Acid- 0.00- 5 locations
  7. Highest Alkalinity- 51.00- Waterloo-Tap
  8. Lowest Alkalinity- 0.00- Oakville
  9. Highest Water Hardness- 110.00- Houston -Tap
  10. Lowest Water Hardness- 30.00 - Caribbean- Tap
My hypothesis was right. When we compared the Mississauga tap water to the other water sources it scored overall best in the different categories. Even though chlorine test was quite high we determined this was because it was tested right away. The other samples were from different locations and we didn’t test in a specific amount of time. This experiment taught me several things. Water is important because:
  1. 75 % of the earth is covered with water.
  2. It keeps you hydrated and healthy. Did you know that your muscles are 75% water; your brain is 76% water, blood 82% water and your lungs 90% water, bones consist of one-quarter water. Water controls the body’s temperature, provides essential nutrition by transporting nutritive elements from the food we eat to our cells, carries away waste products. All living things need water - humans, plants, and animals
  3. 97 % of earth’s water is in the oceans. Only 3 % of the earth’s water can be used as drinking water.
  4. Although a person can live without food for more than a month, a person can only live without water for approximately one week. Clean water is the single most important substance we consume, only oxygen is more essential for human life
  5. It is a very important resource - if we aren’t careful with it - we will lose it.

    Water quality is determined by:

    1. the presence and quantity of contiminants,
    2. by physical/ chemical factories

    Testing the water is done for several reasons.

    1. To maintain a high water quality standard for domestic and buissness use
    2. To ensure that our streams, river, and ponds are clean enough to support the great variety of life, which includes fish, insects, birds, mammls, plants, and even bacteria.
    3. An increasing amount of industrial toxic waste in being poured into our lakes and rivers. Chemicals, fertilizers, and toxic sprays used aon the land continue to pollute the waterways.
