Additional Property Attributes

The findings and conclusions of this Phase II ESA are summarized as follows: � Range 1 Soil: No PAHs were detected in Range 1 soil. � Range 2 Soil: A total of ten (10) PAHs and six (6) RCRA metals were detected in Range 2 soil; five detected RCRA metal concentrations and all detected PAHs concentrations were below applicable SWSs. Arsenic was reported at a concentration at SB3 above the SWS. � Groundwater: A total of two (2) RCRA metals were detected in groundwater; however detected concentrations were below applicable SWSs. Additionally, two (2) PAHs, five (5) VOCs, and eight (8) herbicides were not detected however both the laboratory reporting limit and MDL are above the corresponding SWS. � Vapor Intrusion: Three (3) compounds detected in groundwater are sufficiently volatile and toxic to present a vapor intrusion risk. Groundwater results for two (2) of these compounds were evaluated using the Johnson and Ettinger Vapor Intrusion Model for Forward Calculation of Indoor Air Concentration and the IDNR Cumulative Risk Calculator. One (1) compound is not available in the Johnson & Ettinger Vapor Model and as such it was not included in this calculation. 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: The investigation identified unacceptable cancer and non-cancer risk for a site resident driven in large part by the arsenic concentration observed in at-depth soils. This arsenic concentration also heavily influenced the unacceptable site worker and construction worker non-cancer risk. The City of Oskaloosa has an IDNR-approved ordinance (Ordinance No. 13.04.420) that effectively prevents the installation of private wells, preventing new well installations on properties located within 200 feet of the municipal water system or in any contaminated area. HR Green recommends that these findings be provided to the City�s Water Department for their records. HR Green recommends notifying the County�s Environmental Services Department of the groundwater results contained in this Phase II ESA, to prevent the installation of new wells on the subject property or on adjacent properties. This action will sever the groundwater ingestion pathway for the subject property. The results of this study identify an acceptable cancer risk for site workers and construction workers, an unacceptable cancer and non-cancer risk for site residents, and an unacceptable non-cancer risk for site workers and construction workers on the subject property. Currently the subject property contains a large paved parking lot and office and commercial structure. The observed concentrations that contributed to the calculated unacceptable risks are from soil collected at a depth of six feet bgs up to a total depth of ten feet bgs and are located under a paved area, with the exception of SB2 which contributed minimally to the calculated risks (<0.01 ppm). As such, the paved parking lot appears to be serving as an effective cap for much of the subject property, effectively severing exposure to the impacted material. However, if any future development or construction on the subject property is to be completed, additional assessment may be warranted to determine the spatial extent of the impacted media and to provide safe handling and guidance for any individuals encountering this material. An additional option at this point would include the filing of an environmental covenant with the subject property identifying the impact observed and limiting excavation and concrete removal activities. Based on the findings of this report, it was provided to IDNR for review and guidance in determining next steps.

Former Use: Aerial photographs appear to depict mining operations on the subject property, which include an access road from the adjoining brick factory and excavation pits, in 1938, 1951, 1956, and 1963. Aerial photographs depict a surfa
