Water Testing
- Test for turbidity (clearness)
- Canadian guideline requires a turbidity of less than 5.0, but the turbidity range in Eagle lake water plant is within 0.1 to 0.3 NTU
- Color, residue, and temperature tests done
Learning outcomes

Challenges
Maintenance of Treatment Plant
Consequences of Improperly Filtered Water
- Filtration of the water again to remove chemicals added in previously.
- A module in the block chamber has 40 cassettes and each modules costs $2000.
- Filtration occurs through red blocks and then the filtered water goes downstairs through a pipeline.
- Filtering water quickly in an emergency situation
- Complications of using chlorine alone to treat the water
- Unfiltered water can cause illness such as diarrhea due to the presence of cryptogardia, ecoli, carcinogenic products
- weather dependent
- vulnerability to contamination
- Physical environmental disturbances
- Cost
Challenges
Health Promotion
- Difficulty reaching out to residence
- language barriers
- sense of entitlement
