	abstract = {The large quantities of sludge and extraction tailings water contained in pondsat the closure of oil sands leases have been identified as significantenvironmental concerns,

Tests have been conducted to assess changes in tailings pond water quality overtime. Biological, toxicological, chemical, and physical parameters have beenconsidered. Results indicate that the quality of top water in an abandoned pondmay be anticipated to Improve with time to an environmentally acceptablecondition. The rate of improvement can be manipulated utilizing known watertreatment technologies.

The lake concept is an application of the information available on addressingthe sludge handling concerns in which the sludge is disposed of under a layerof reclaimed top water.

A scheme for using the lake concept has been Incorporated Into a leaseabandonment plan for the Suncor oil sands project. The plan, which incorporatesexisting knowledge on sludge properties and dynamics, demonstrates a practical,environmentally sound approach for a facility which is in currentoperation.},
