Water Quality Monitoring

At the sample sites…
Temperature, pH, dissolved oxygen
Estimates of creek depth, width flow
In the lab…
Nitrate, phosphate, chloride
Organic matter (biological oxygen demand)
Bacteria (E. coli and total coliform)

Conclusions

The Chedoke watershed adds N and P to Cootes

Paradise

Mountview and Cliffview are most contaminated
Chedoke (due to its higher flow rate) is the largest

source

Reducing the amounts of N and P added to this

watershed would help improve water quality of Cootes Paradise and Hamilton Harbour

Future monitoring is planned to track

improvements
