2016-01-21 Item 8C - Laurel Cove MND Appendix 9HILLMANN CONSULTING March 21, 2014 Mr. BJ Delzer Delcon, Inc. 8951 Research Drive, Suite 100 Irvine, CA 92618 Re: Supplemental Pesticide Sampling Report 720 San Andrade Drive Encinitas, California Dear Mr. BJ Delzer: { }j APR 2 5 2014 VIA EMAIL As requested, Hillmann Consulting, LLC ( Hillmann) conducted supplemental soil sampling for pesticides for Delcon, Inc. at the above referenced site. Hillmann previously performed a Phase I Environmental Site Assessment (ESA), dated March 12, 2013 for the site. The ESA indicated that from at least the 1990's until the present the property was utilized for agricultural purposes. Based on this finding it was considered likely that pesticides had been used at the site, posing a recognized environmental condition (REC) on the site. In August 2013, Hillmann conducted shallow soil sampling at the site, collecting samples from 0.5 feet below grade in six targeted locations (S- 01- S -06). Results indicated no detectable levels of organo- chlorine pesticides or arsenic, and only low, background levels of lead (maximum of 8.3 mg/Kg). These results were submitted to the City of Encinitas, who requested additional sampling to verify that the deeper soil was not impacted. This report presents the findings of the supplemental investigation. FIELD ACTIVITIES On March 13, 2014, Hillmann installed six soil borings in the same general locations as the previous borings installed on August 28, 2013 (designated S -01 through S -06). The borings were installed using a hand auger tool to 2.5 -3.5 feet below grade. The locations of the borings are shown on Figure 1, included in this report as Appendix A. During hand augering, saturated soil was encountered at 1.5 feet below grade in borings S -01 and S -02. Very moist soil was encountered in the other borings to the maximum depth drilled of 3.5 feet below grade. The soil encountered during hand augering consisted of mixed sediments Your Property.

The boring Iogs include descriptions of the sediments in each location and are included in Appendix C. The soil samples collected from the maximum depth in each location were preserved in laboratory glass jars, sealed with Teflon tape and plastic caps, and stored on ice in a cooler during transport to a Califomia certified laboratory under chain -of- custody- protocol. All soil samples were analyzed for organo - chlorine pesticides via EPA Method 8081 A, and for arsenic and lead by EPA Method 6010. In addition, a grab groundwater sample was collected from the open borehole of boring S -02, and was stored in a I -liter poly laboratory container. This sample (S -02- Water) was also analyzed for organo - chlorine pesticides, arsenic, and lead. RESULTS The laboratory results indicate none of the soil samples had detectable levels of organo - chlorine pesticides or arsenic. One sample had detectable levels of lead with 19 mg/Kg detected in sample SO4 -3. This concentration is well below the California Human Health Screening Levels (CHHSL) for lead in soil (80 mg/Kg in a residential setting and 320 mg/Kg in a commercial setting). The grab groundwater sample from boring S -02 did not have detectable levels of organo - chlorine pesticides, arsenic or lead. A summary table is included as Tubie 1. The full analytical data report is included as Appendix B. CONCLUSIONS AND RECOMANDATIONS Based on the data included in this report no additional soil sampling or remedial action is recommended.
