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, an observed release or observed contamination is established when contaminants that are significantly above background levels have migrated away from a site through environmental media. This fact sheet describes how to determine background levels for each migration pathway, and emphasizes the necessity of strategic, efficient sampling, which is particularly important in light of conducting integrated assessments under the Superfund Accelerated Cleanup Model (SACM).
Availability Notes Paper copy available on Standing Order, deposit account required ($100 U.S., Canada, and Mexico; all others $200). Single copies also available in paper copy or microfiche.
