4. Wait for 3 minutes, and then compare the colour (look at the beaker from the top) with the CGLS (giving CGLS a rating of 10), estimate what the other beakers contain, the lighter the colour, the lower your rating. Write down the ratings that you got for each sample. Results: The Canadian Guideline Limit Sample for iron of 0.3 mg/L was rated 10; a lower rating (lighter colour) means that the water meets the guideline; a rating higher than 10 means that the water Does Not meet Canadian Drinking Water Guidelines.
