The Confederated Tribes of the Colville Reservation Environmental Trust mission is to achieve & maintain a healthy environment with functioning ecological systems including biodiversity, clean water, clean air and healthy soils required to support plants, animals, tribal values and subsistence uses.

Derelict Housing Structures

 The derelict (abandoned) structures include residential and commercial buildings on the Colville Indian Reservation.  Hazardous building material inspections were conducted as a pre-demolition requirement. These materials include the presence of asbestos, lead based paint, lighting, and electrical components.  Sampling components include wood, glass, concrete, metal, fiberglass insulation, flooring, roofing, piping, railings, plumbing, and ducting.  The inspections were designed to assist with special handling or waste characterization prior to disposal as a result of modernization and demolition activities.
