Caution: Since Russell Lake is a shallow lake, the standard limnetic (i.e., open-water) trophic parameters may not represent the true trophic status of the lake.

Chemical vs Biological monitoring

  • Deep station total phosphorus (TP)- comparison with our hindcast models; October 18, 2013
  • Phosphorus:- Details on LCC (Lake Carrying Capacity)/Threshold values of lakes, and comparison with artificially high values chosen by the HRM; March 14, 2014

  • Total stormwater treatment recommended:

    Total stormwater treatment should also include removal of other urban pollutants as well, not just phosphorus! The CDS technology, the Stormceptor, and the Vortechnics are superb devices for pre-treatment, but they have to be followed by sophisticated polishing systems, for example a scientifically designed wetland with the attendant maintenance in perpetuity. This combination may or may not work (see the note of caution).

    A note of caution: There have been conflicting results in the long term removal of typical stressors in storm drainage using constructed (or engineered) wetlands. Further, such wetlands have not had a successful history in the amelioration of acid drainage in HRM. Hence, the only sustainable methodology would be treatment of urban and suburban stormwater by traditional wastewater treatment plants (WWTP) based on the tertiary removal process in the case of stressed lakes. This implies considerable capital costs and operation & maintenance.
