1. 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.)
