Bio-Indicator Trading Cards Look at each bio-indicator on the following slide and determine which ones you would want and which you wouldn’t in your water around your house. This will work like a draft, some may not be available once another group takes them! Prepare ahead of time before your turn! (Each bio-indicator has different abilities to survive (tolerance levels). Various water quality indicators show how tolerant each bio-indicator is, and these are provided in the following slides.)

Example of How to Determine Quality Draft Choices Trosclairian Good Choice Bad Choice Trosclairian Goodmanis pH Level: 6.0 - 8.0 Turbidity Tolerance: Low to None Thermal Pollution: Low to None Dissolved Oxygen: High pH Level: 3.5 - 10.5 Turbidity Tolerance: High Thermal Pollution: Medium Dissolved Oxygen: Low
