Soil health index in remediation of contaminated sites. Approach and application.

The soil health index is an approach for assessing the ecological potential of a soil. The index is based on a physical, chemical, and biological characterization and rating of soil conditions. The approach is flexible, permits comparisons amongst soils with widely different properties and contaminant levels, and it can be adapted to site specific conditions. The rationale and development of the index are documented in this report along with sample handling, assessment methods, and quality assurance practices. Standardized reporting formats have also been developed for compiling and presenting the findings. An interpretive guide is included for the reporting formats and how to apply the results to site specific conditions.
