Abstract
EPA uses the Hazard Ranking System (HRS) (40 CFR Part 300, App. A) to evaluate Superfund sites to be proposed on the National Priorities List (NPL). Based on the HRS criteria, an observed release is established when contaminants have migrated away from a site through environmental media. This fact sheet describes an observed release, the data required, and the process used to document it. Efficient sampling also is emphasized to optimize the use of limited resources, which is especially important in light of conducting integrated assessments under the Superfund Accelerated Cleanup Model (SACM).
