FINAL ASSESSMENT REPORT
EXECUTIVE SUMMARY
PRESS RELEASE
In the Stage 1 report, that outlined the environmental problems facing the Bay of Quinte, this BUI was indentified as impaired due to excess algae. The criteria established for this BUI was related to reducing excess algae, which would improve water clarity.
However, it was noted that the Bay of Quinte RAP restoration
target and measure did not align with the IJC’s original intent for the
Aesthetics BUI which was to identify the following impacts that adversely
affect the “aesthetics” as a beneficial use in the AOC:
- Unnatural/man-made impacts;
and
- Near-shore impacts
In 2018, the BUI criteria was revised to address the original
intent of the BUI.
New Target:
Nearshore
surface waters of the Bay of Quinte are free of any substance due to human
activity that produces a persistent objectionable deposit, unnatural colour or
turbidity or unnatural odour (for instance, oil slick or surface scum).
Monitoring staff have collected data for man-made issues related to: water colour, clarity, odour and debris.
In 2018, the Bay scored at 9.5 or Excellent. In 2019, the Bay scored at 9.8 or Excellent.
