risk-based site closure

Risk-Based Closure

What's the best path to closure for your site?

Risk-based closure evaluates site environmental conditions and area sensitive receptors to determine if an alternative to strict numerical regulatory closure standards would be appropriate. Considerations for risk-based closure include:

  • Future site use
  • Property use restrictions
  • Area property use (industrial, commercial, residential)
  • Soil, groundwater, surface water, and indoor air exposure pathways
  • Groundwater impact trends

Antea Group has decades of experience evaluating environmental risk, and our multi-disciplined teams have deep regulator and state-specific knowledge (including states with formal risk or tiered approaches, including Delaware, Maryland, Washington DC, Iowa, Alabama, and California.) When combined with our air, soil, and groundwater risk evaluation expertise and our data visualization capabilities, that's a combination you can't beat.

Risk-Based Closure Services

Utilizing a combination of state-specific alternative standards and national guidance documents (ASTM, ITRC), risk-based closure evaluates site environmental risk relative to area-wide receptor sensitivity. Typical risk pathways incorporate one or more of the following:

  • Plume stability evaluation
  • Absence of LNAPL demonstration
  • Property use restrictions
  • Area sensitive receptor evaluation
  • State-approved risk evaluation models
  • State alternative or tiered contaminant standards
