The 2008 National Classification System for Contaminated Sites (NCSCS) is used by federal departments and agencies to prioritize contaminated site management funding. In this paper, site scores calculated using the 2008 NCSCS are compared to hazard quotients calculated using a preliminary quantitative risk assessment (PQRA) protocol to assess whether acceptable correlations exist. The authors conclude that NCSCS site scores are positively correlated with PQRA hazard quotients, but the data scatter precludes developing defensible mathematical relationships.
