Water Quality & Distribution

LESSON MATERIALSmove

Fun Facts

  • If water contains too many pollutants, plants and animals will not survive.
  • Humans pouring chemicals into water can negatively affect water quality.
  • Scientists look for sensitive organisms in bodies of water to indicate the water quality.

Why Do We Need To Know About Water Quality

Learning about water quality helps us know why it’s so important for plants, animals, and people to have clean water. Dirty water can harm all living things, showing why we need to keep our water clean for our health and the environment. This involves making sure our water is safe for drinking, growing food, and keeping nature healthy.

Studying water quality can lead to jobs in environmental science, engineering, and biology. Efforts like ‘Heal the Bay’ and cleaning wastewater help keep our water safe for swimming, help fish and other water creatures live, and make sure our water is clean for farming and fun activities. This shows how taking care of our water is good for our health and the environment.

Frequently Asked Questions

Why did Dr. Jeff mention the presence of dead zones when talking about water quality?
Dead zones are areas where algae blooms grow. These blooms grow because polluted runoff reaches the ocean. Poor water quality can cause these blooms to form.
How did the team describe the three stages of a water filter?
The first stage separates out large particles from getting into water. The second stage has fine pieces of carbon. This helps absorb impurities in the water. The last stage consists of a fine mesh that takes out extremely small particles from the water.
How is water distributed on earth in terms of freshwater and saltwater?
97% of all the water on Earth is saltwater while only 3% is freshwater. This means bodies of water like rivers and lakes are part of the 3% while oceans make up the 97%.
