5. Pollutant Removal How should these pollutants be removed? – ___________________

6. All pollutants together Initial observations3 min. observations5 min. observations Describe what you see at the following times: Final TDS= ______________Final pH= ______________

7. Removal of pollutants How would you remove the pollutants now? – Should it be filtered? – Should it have bleach added to it? – Should it have other chemicals added to it? – If you did this – would the resulting water be safe to drink? – If the Assiniboine River looked like this… what could we do to it?
