S/S Milestone!

Friday, June 24, 2011 marks another milestone for the Sydney Tar Ponds and Coke Oven Cleanup Project -The Solidification and Stabilization process (TP6B) is at the official half-way mark according to schedule. With 10-15 cells being completed a day and 1543 cells completed to date, the project is right on schedule.

The S/S process includes using an excavator to mix cement powder into the contaminated sediment, similar to the way a baker mixes ingredients when making a cake. The contract requires that each completed cell meets established criteria for permeability, leachability, and strength.
