Air Groundwater Soil Chemical Max, ug/m3 Max, ug/L Max, mg/kg Benzene 3.6 20 .5 TCE 1.2 10 .36 Arsenic 6.5e-2 10 8.8e-1 1. For each compound, determine if the maximum concentration is above USEPA RBC screening values. 2. Determine the Risk/HI as appropriate for all compounds listed in Table 1 from dermal contact of soils by residents. Note that some chemicals may require evaluation as both carcinogens and non-carcinogens. 3. Determine the Risk/HI as appropriate for all compounds listed in Table 1 from ingestion of water by on-site residents. 4. Determine the Risk/HI as appropriate for all compounds listed in Table 1 from inhalation of contaminants by on-site resident. 5. Determine Total Risk/HQ for this resident from these 3 pathways. answer for this question
