This public health risk assessment evaluates the risks associate with the on-site incineration of basin F liquid at RMA. The populations evaluated include 1 on-site workers, 2 Irondale as a population center, 3 fencelike at the point of highest exposure, and 4 residences and school that had the highest modeled exposures. The range of carcinogenic risks for the populations evaluated is 3.26E-09 to 4.55E-07. These risks are less than the range accepted by the EPA at remediated superfund sites. The hazard index noncarcinogenic toxic effects values range from 2.47E-06 to 3.69E-03 and are not a cause for concern. The following steps in public health risk assessments are discussed 1 Selection of indicator chemicals, 2 Selection of potentially exposed populations, 3 Identification of potential exposure pathways, and 4 Estimation of exposure concentrations.
