Abstract

Human health risk assessment at hazardous waste sites with population heterogeneity Jagath J. Kaluarachchi & Qian Zhao Utah Water Research Laboratory, Utah State University, Logan, UT, USA Abstract For the past few decades, analysis relevant to remediation of groundwater contamination at hazardous waste sites has been conducted using the applicable maximum contaminant levels. However, recent research has shown that a more efficient and economical approach is to use the risk-based corrective action. Although risk assessment is now routinely conducted at many major sites, the methodology has many limitations, especially related to incorporation of population heterogeneity. The research described in this paper demonstrates the importance of considering population heterogeneity related to age and gender in the analysis. 1 Introduction In the past few decades, the maximum contaminant level (MCL) criterion was used as the cleanup goal when developing management strat
