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

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
