Proposed Work
Done
Phase 1Characterization of canal waters before remediation
IS DONE
Phase 2Monitoring water quality changes after remediation.
TO BE DONE
Strategies
‐ Monitoring will begin in remediated canals six month after remediation and will be performed quarterly.
‐ Non remediated canals will be monitored at least once per year
