How do we handle the contaminants??--Environmental Statement

Environmental Statement
By Rob MacLeod and Larry Bean

The Livery building can be used in a manner that is protective of human health and the environment. The Livery Building is completely reusable once the inner surface is sealed. The last occupant of the Livery Building was Longworth Plating. They were a small plating operation that hand dipped parts (trophies, machine parts) to add a metal coating to them. As is typical with all plating operations, some of the solutions ended up on the floors and in the ground below the building. The solutions had heavy metals in them that have the potential to be a health risk. Typically heavy metals don’t move in the environment without some carrier like acid or other liquid to mobilize them. The heavy metal contamination on the floor and below the building can be sealed in place by resurfacing the floor. The metals contamination in the soil and groundwater below the building will not affect the use of the building. An epoxy floor and paint on the walls will create an exposure barrier that will protect any users of the building from any residual contamination on the floor or walls. The tanks in the back have been cleaned and can be closed out by filling them and covering them with concrete.
