The primary objective of environmental remediation is to reduce potential exposures to hazardous substances to acceptably safe levels. The determination of cleanup objectives frequently involves the adoption of existing standards, such as federal drinking water standards, even when such standards are more restrictive than warranted by the potential exposures associated with identified future use scenarios.
When remediation to the adopted standards is technically infeasible, economically prohibitive, and/or only achievable over long timeframes, it may be appropriate to establish risk-based cleanup standards. This approach is suitable for evaluating the adoption of appropriate or relevant and applicable requirements (ARARs), and for establishing cleanup objectives for sites where regulatory requirements are not well defined, such as sites with elevated levels of naturally occurring radioactive materials.
Involving stakeholders in the risk-based decision-making process will ensure that societal needs and constraints are addressed, along with the technical and economic constraints, to establish sustainable and equitable remediation.
Join our panel of speakers in examining opportunities and constraints related to identifying appropriate dose- and risk-based remediation objectives from both the site owner/operator and regulator perspectives.
"Using Risk Assessment to Guide Environmental Remediation Decisions" is from 11:30 a.m. to 1 p.m. PDT, Tuesday, July 26. Registration is free, click on ZoomGov to sign up in advance or join the event. The session is free and open to the public as part of the Center for the Remediation of Complex Sites (RemPlex) seminar series.
