Solution
After decades of study, the federal and Nova Scotia governments concluded that the best way to deal with the Sydney Tar Ponds is to stabilize, solidify, and contain the contaminated material. In January 2007, officials from Ottawa and the province announced a $400-million plan to solidify the toxic sludge using the Solidification / Stabilization (S/S) with Cement method. This technology was preferred over a controversial proposal to incinerate some of the 700,000 tonnes of sludge. Nordlys Environmental LP and ECC were awarded a $52-million contract in October 2009 to begin S/S operations.
Environmentalists and local residents continued to worry officials would incinerate some of the material, though Federal and provincial officials claimed the S/S method they had chosen would stabilize the 100-hectare site without producing any adverse health or environmental effects.
The first phase of the project was completed in mid-December 2009 and work will continue with Phase 2 in the spring of 2010. Eventually the area will be covered with an impermeable barrier, soil, and finally grass. Parts of the restored site may eventually be used for recreational purposes.

“All the followers of science are fully persuaded that the processes of investigation, if only pushed far enough, will give one certain solution to each question to which they can be applied.... This great law is embodied in the conception of truth and reality. The opinion which is fated to be ultimately agreed to by all who investigate is what we mean by the truth, and the object represented in this opinion is the real.”
—Charles Sanders Peirce (1839–1914)
“The Settlement ... is an experimental effort to aid in the solution of the social and industrial problems which are engendered by the modern conditions of life in a great city. It insists that these problems are not confined to any one portion of the city. It is an attempt to relieve, at the same time, the overaccumulation at one end of society and the destitution at the other ...”
