De minimis <br />conditions are not considered RECs. <br />3.2 Findings and Opinions <br />Barr has identified the following findings and developed the following opinions regarding these findings, <br />as summarized in the following table. <br />Finding ID # Description of Finding Opinion with Respect to Finding (REC, CREC, HREC, de minimis) <br />Finding #1 Groundwater PFAS Impacts in the East Metro Area: Nearby Superfund sites have been identified by the state as contributing sources of widespread PFAS contamination in groundwater, including the Washington County Landfill, located approximately 3,000 feet northeast of the Property, and the Oakdale Dump site, located 3,600 feet west of the <br />Property. Both sites are estimated to be side-gradient of the <br />Property for shallow groundwater, and the Washington <br />County Landfill site may be upgradient of the Property for groundwater in bedrock. Drinking water advisories have been issued for private wells southeast of the Property. No wells are currently present on the Property. The Minnesota Department of Health has designated a Special Well Construction Area in this part of Lake Elmo that includes the <br />Property, which restricts well construction in some cases and <br />requires PFAS sampling of new wells in other cases in order <br />to prevent exposure to PFAS. City water is available near the Property. Additionally, the state is currently implementing area-wide investigations and remedial efforts to address PFAS in the East Metro Area. <br />The PFAS in groundwater is a regional concern and institutional controls are in place to address PFAS in Lake Elmo groundwater, therefore this finding is not considered a REC. <br />Finding #2 Miscellaneous Debris: Occasional areas of miscellaneous, inert debris were observed dispersed across the site. Observed materials included wood, metal fragments, plastic and glass shards, a small ash pile, and a stack of cinder blocks. <br />Based on the quantity and nature of the debris, this finding is considered a de minimis condition and is not a REC. <br />Finding #3 Past Agricultural Use: The Property has been used for agriculture since at least 1936 and there is potential for agricultural chemicals to have been used at the Property. <br />Because it is assumed that agricultural chemicals were applied using industry standard application <br />rates, and no evidence of inappropriate agricultural chemical applications was identified, this finding is not a REC. <br />Finding #4 Adjoining LUST Site: One closed LUST site was reported at an east-adjoining, down-gradient parcel. Soil and groundwater contamination was reported and delineated in the regulatory records. <br />Based on the downgradient location of the LUST site, this finding is not a REC.
