Assessing Non-Carcinogenic and Carcinogenic Health Risk for Chlorinated Solvent Contaminated Groundwater Using MUSt Software Palckage: Case Study

Chlorinated solvents can degrade to generate transformation products sequentially. The presence of such transformation products must be considered for the health risk assessment. Recently, we have developed a software package MUSt (MUltiSpecies transport Analytical Models) in which FORTRAN executable files based on our newly developed multispecies transport analytical solutions are equipped with an interactive graphical user interface (GUI). The multispecies transport analytical solutions embedded in MUSt have been further combined with health risk module for more reasonable health risk assessment. This study assesses the health risk for chlorinated solvent contaminated groundwater in northern Taiwan. The geographical distribution of non-carcinogenic and carcinogenic health risk is depicted for appropriate action for reducing groundwater concentration level of chlorinated solvent contaminants and protecting human health.
