Tiered Approach to Corrective Action Objectives
Tiered Approach to Corrective Action Objectives (TACO) is the Illinois EPA's method for developing remediation objectives for contaminated soil and groundwater. These remediation objectives protect human health and take into account site conditions and land use. Remediation objectives generated by TACO are risk-based and site-specific.
