Brownfield Remediation Process, in general...
1. Determine the scope of the contamination and form an action plan through a conceptual site model. Test water and soil to identify contaminants. Assess the impact on surrounding land, water resources and watersheds that may be contaminated.
2. Review the feasibility of project to determine budget, time frame and the necessary stakeholder input.
3. Use dynamic work strategies to start cleanup projects quickly without pre-project analysis. By building flexibility into the management plan, project managers can allow for different courses of action should they be necessary. The project can then evolve with the cleanup efforts
4. Assess data with real-time measurement technologies. Continued testing and analysis helps assess the progress of the project and its impact on the surrounding environment. These assessments can then drive the dynamic work strategies discussed above.
5. Plan redevelopment of reclaimed lands by assessing the outcome of cleanup efforts.
