Microflora Impacts on Water Treatment Plants & Their Solutions

  • in-house algae and microflora identification
  • microflora clogging and water chemistry impacts on treatment plant efficiency
  • toxicity of cyanobacteria
  • taste and odor in drinking water

Reclamation of Mine Tailings Water Covers

  • modifying water chemistry to support primary production
  • introducing bacteria, algae, aquatic macrophytes and invertebrates to barren tailings ponds and sludge ponds
  • installing riparian shrub and emergent vegetation from stakes, plugs and seed
  • monitoring thermal behavior with data loggers
  • creation of sustainable fisheries and wetlands

Development of Pit Lakes as Bioreactors & Fishery Habitat

  • inducing algae blooms to transport aqueous metals via algal adsorption to non-mixing bottom water in deep pit lakes
  • identified role of B vitamins in pit algal production
  • use of enhancement techniques such as aeration, fertilization, plant invertebrate introduction, bio-reefs, bio-islands, sulphate reducing bacteria
  • development of trophy fishery habitat

Biologically Mediated Mine Water Treatment

  • reactor design based on bench studies
  • design and operation of sulphate reducing bacteria (SRB) reactors and wetlands
  • monitoring of water quality improvements made by SRB ponds, wetlands and reactors

Data Management & Analysis

  • experience handling large datasets
  • automated water quality guideline exceedance analysis
  • advanced statistical analyses
  • data visualization
  • digital mapping
  • web-based data application and tool development

Underwater Infrastructure Assessments

  • LAC operates an underwater remotely operated vehicle (ROV) with depth range up to 100m and HD video camera
  • detailed surveys of submerged infrastructure including intake and outfall pipes
  • cost is significantly less than divers
