  1. 37.Water Quality Testing • EQ: How can we determine the safety and drinkability of our water supplies? • LT: I can describe the indicators of water quality and what are acceptable levels . • POU: I will identify the indicators of water quality. I will determine whether or not a sample of water is in the normal range for a particular water quality indicator. I will compare samples of water in the water quality tests lab.

  2. Welcome! Warm Up 3/24/14 What are two factors that will increase the number of fish the ocean? • Upwelling zone and photosynthesis • Upwelling zone and chemosynthesis • Hydrothermal vent and photosynthesis • Hydrothermal vent and chemosynthesis • Enter your response at www.goo.gl/vta7d1

  4. Notes: Indicators of Water Quality • There are 6 indicators of water quality that we are going to study: • Turbidity • pH • Dissolved Oxygen • Temperature • Nitrates/Ammonia • Bio-Indicators

  5. Turbidity: measure of the degree to which water looses its transparency due to the presence of suspended particulates (“tiny particles”) Definition:

  6. pH: the acidity of the water (presence of hydrogen ion) 07 is acidic 7 is neutral 714 is basic Definition:

  7. Dissolved Oxygen: the oxygen dissolved in the water Definition:

  8. Temperature: measure of average kinetic energy Definition:

  9. Nitrates: compound that contains the nitrogen based polyatomic ion NO3 (Ex: Sodium Nitrate) Definition:

  10. Water Quality Tests LAB • Today you will have the opportunity to conduct water quality testing of three samples of water: • pond water • dirty soil water • Filtered water
