Additional Property Attributes

The Phase II ESA report identified the following: � Range 1 Soil: A total of five (5) RCRA metals were detected in Range 1 soil and all detected concentrations were below applicable SWSs. Additionally, arsenic was not detected however both the laboratory reporting limit and MDL are above the corresponding SWS but below the previous background standard. � Range 2 Soil: A total of sixteen (16) PAHs and five (5) RCRA metals were detected in Range 2 soil and all detected PAHs and three (3) RCRA metal concentrations were below applicable SWSs. Arsenic was detected above the SWS and below the previous background standard. Lead was detected at SB2 at a concentration above the SWS and below the non-residential standard (1,100 mg/kg) which is suitable for the planned commercial or industrial site use. � Groundwater: A total of two (2) RCRA metals and one (1) VOC were detected in groundwater and all detected concentrations were below applicable SWSs. Additionally, one (1) PAH and five (5) VOCs were not detected however both the laboratory reporting limits and MDLs are above the corresponding SWS. � Vapor Intrusion: Six (6) compounds detected in groundwater are sufficiently volatile and sufficiently toxic to present a vapor intrusion risk. 1,2-Dibromo-3-chloropropane is sufficiently volatile and toxic, but it is not included in the Johnson and Ettinger Vapor Model and as such it cannot be included in this calculation. Groundwater results for the remaining five (5) compounds were evaluated using the Johnson and Ettinger Vapor Intrusion Model for Forward Calculation of Indoor Air Concentration and the IDNR Cumulative Risk Calculator. The calculated results for this media indicate that vapor intrusion alone does not pose a risk on this site. Cumulative risk is discussed below. � Cumulative Risk Evaluation: Calculated cancer and non-cancer risks for accessible pathways for site residents, site workers, and construction workers. All cancer and non-cancer health risks for site receptors are acceptable based on the findings in this report. All cancer risks and the non-cancer health risks for site workers and construction workers are acceptable based on the findings in this report. The site resident non-cancer health risk is unacceptable and this is primarily associated with the observed lead and arsenic concentrations. The results of this study identified acceptable cancer and non-cancer risks for all non-residential site users and unacceptable non-cancer risk for a residential site user. The unacceptable non-cancer risk is primarily associated with the observed arsenic and lead concentrations. Based on the findings of the report, a non-residential site use is appropriate for the subject property as identified by the risk calculations and the observed lead in soil results reported at a concentration below the non-residential standard of 1,100 mg/kg. All detected groundwater concentrations were observed below applicable SWSs. The elevated groundwater risks identified in the report are associated with non-detect values and a conservative risk determination approach where the non-detect value was used to calculate risk for each compound with a MDL and laboratory reporting limit above the applicable SWS. Further, the Black Hawk County has an IDNR-approved ordinance (Health Dept. Regulation 1-99) that effectively prevents the installation of private wells, requiring that connections be made to public water supplies and if that is unavailable a permit would be required. Public water supply is available to the subject project. As such, the groundwater pathway is severed and does not appear to pose a risk to the subject property. HR Green recommended providing the report to IDNR for review and guidance due to the elevated concentrations observed in soil. IDNR issued a response letter on 03/23/20 that stated the contamination detected in soil and groundwater do not constitute a hazardous condition.
