37.Water Quality TestingEQ: 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.
Welcome! Warm Up 3/24/14

B. Upwelling zone and chemosynthesis
C. Hydrothermal vent and photosynthesis
D.Hydrothermal vent and chemosynthesis

Notes: Indicators of Water QualityThere are 6 indicators of water quality that we
are going to study:TurbiditypHDissolved OxygenTemperatureNitrates/AmmoniaBio-Indicators
Defi
nit
ion
:Turbidity: measure of the degree to which water looses its transparency due to the presence of suspended particulates (“tiny particles”)
Defi
nit
ion
:pH: the acidity of the water (presence of hydrogen ion)
07 is acidic
7 is neutral
714 is basic
Defi
nit
ion
:Dissolved Oxygen: the oxygen dissolved in the water
Defi
nit
ion
:Temperature:
measure of average kinetic energy
Defi
nit
ion
:Nitrates: compound that contains the nitrogen based polyatomic ion NO3
(Ex: Sodium Nitrate)
Water Quality Tests LABToday you will have the opportunity to
conduct water quality testing of three samples of water:
1. pond water
2. dirty soil water
3. Filtered water
