Celilo Village Environmental Baseline Study

Celilo Village Environmental Baseline Study

As part of a major redevelopment of historic Celilo Indian Village, a multi-disciplined team of engineers and planners prepared a comprehensive environmental baseline study for the 120-acre property located adjacent to the site of the inundated Celilo Falls on the Columbia River.

The site included two solid waste disposal areas, an existing and abandoned sewage sludge lagoon, underground storage tanks, lead based paint and asbestos issues.  We prepared and implemented a sludge sampling plan to evaluate land application or off-site disposal alternatives; conducted lead-based paint and asbestos surveys for over 20 buildings; and prepared construction specifications and permit applications for abandoning the old sewage sludge lagoon and construction of a new system.
