• One or more OCPs were detected in two (2) of the 15 samples. The detected compounds <br />included 4,4-DDE (maximum detection of 0.036 milligrams per kilogram (mg/kg)) and 4,4- <br />DDT (maximum detection of 0.0031 mg/kg). The residential human health risk based <br />screening levels for these compounds are 2.0 mg/kg (4,4-DDE) and 1.9 mg/kg (4,4-DDT). <br />OCPs were not found to be contaminants of concern. <br />• Total arsenic and lead were detected in each of the 15 samples at maximum concentrations of <br />5.9 mg/kg (arsenic) and 52 mg/kg (lead). The detected arsenic concentrations were below the <br />commonly applied ambient screening level of 12 mg/kg for this element (indicative of naturally <br />occurring concentrations in southern California soils) and the detected lead concentrations <br />were below the residential human health risk based screening level of 80 mg/kg. <br />• No additional assessment was recommended. <br />Phase I Environmental Site Assessment January 16, 2022 <br />Cabrillo Town Center, Santa Ana, CA <br />ouncil 18 —1116 10/3/2023 <br />
