For the past 17 years Mr. Spengler has been remediating contaminated soils either immediately before or during grading operations. He has had the opportunity to implement several different approaches and has the experience to know when a specific approach will work best. There are numerous factors that should be considered when selecting a remediation approach such as:

• Cost
• Schedule
• Value (effectiveness of the assessment)
• Feasibility
• Coordination with other activities and needs
