USEPA and Beazer Final Koppers Feasibility Study 5-11-2010



Human Health Risk Assessment (On-site only)

Superfund risk assessments determine how threatening a hazardous waste site is to human health and the environment. Risk Assessors seek to determine a safe level for each potentially dangerous contaminant present. For humans, this is a level at which ill health effects are unlikely and the probability of cancer is very small. This Web site contains information on the Superfund risk assessment process and links to various risk assessment guidance documents. (Note 1.)
