Analysis of TrendsAnalysis of Trends

• Solidification and stabilization popular

• Treatment has not closed the cost gap

• Confined disposal greater acceptance

• Beneficial reuse coming of age

Analysis of Trends (continued)Analysis of Trends (continued)

• Well-Tested - CDF Technology

• Evolving - Suitability Evaluation

• Largest Hurdle - Siting and Permitting

• Silver Bullet - There is none
