Our Role:

• Ran project from 1999 to 2004 as PRP's Project Manager

• 140-acre, former tin smelter
• Historically significant, only tin smelter in U.S. during WWII
• Contaminants all inorganic; in soils, sediments, sludges, groundwater and waste products (e.g., slag)

Project Metrics:

• Approximately:
  • 9,600 cu.yds of impacted ditch sediment
  • 52,000 cu.yds of acid pond sludges

Completed Goals:

• Treat in place
• Dispose onsite
• Strengthen to allow further site development

Lessons Learned:

• Volume estimates always incorrect; contract accordingly
• Adjustment of reagent mix can reduce costs
