Receipt
The samples were received on 4/ 16/2020 2:38 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 2. 70 C.

GC Semi VOA
Method 8081A: The RPD of the laboratory control sample( LCS) and laboratory control sample duplicate( LCSD) for preparation batch 570- 63501 and analytical batch 570- 63508 recovered outside control limits for the following analytes: alpha- BHC, Aldrin, beta- BHC, Dieldrin, Endosulfan I, Endosulfan ll, Endosulfan sulfate, Endrin aldehyde, Endrin ketone, gamma- BHC, Heptachlor and Heptachlor epoxide. The associated MS/ MSD precision was within acceptance limits. therefore data has been reported and qualified.

Method 8081A: Due to the additional level of 4,4'- DDE and 4,4'- DDT present in the spiked samples, the concentration of 4,4'- DDE and 4, 4'- DDT in the MS/ MSD was above the instrument calibration range. The data have been reported and qualified.

Method 8081A: The continuing calibration verification ( CCV) associated with batch 570- 63736 recovered above the upper control limit for Hexachlorobenzene>. The samples associated with this CCV were non- detects for the affected analytes; therefore, the data have been reported.

Method 8081A: The continuing calibration verification( CCV) associated with < Analytical Batch> recovered high and outside the control limits for< Endosulfan sulfate> on one column. Results are confirmed on both columns and reported from the passing column.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/ Glossary page.

Hi Steve,
We would like to perform the following additional analysis on samples that you have from job number J25057- 1 and 125647- 1:
64- 0. 5, 134-3. 0, 136-0. 5, 86- 3. 0, 67- 0. 5, 67- 3. 0, 68- 0. 5, 68- 3. 0, 139-0. 5, 139-3. 0, B10- 0. 5, and B10- 3. 0 for Title 22 Metals EPA 601013/ 7471A and Hex Chrome EPA 3060A/ 7199.

Please let me know if you have any questions.

Subject: RE: Huntington Beach 17631 Cameron Lane analysis questions Laura-

1. Would it be possible to have all 50 samples re- run for herbicides and Title 22 Metals? EPA8151 for herbicides and EPA601013/7471A for Title 22 metals- yes. Holding time for EPA8151 is 14 days. Sample collected prior to or on 04/ 08/ 20 are already past holding time.

2. Would it be possible to re- run some of the samples for hex chrome? Yes— EPA 3060A/ 7196A or EPA 3060A/ 7199?

3. What would be the cost for these analyses on a 5-day TAT and a 48- hour TAT? EPA 8151 -$ 200 on 10 day TAT.

EPA 601013/ 7471A for Title 22 metals-$ 80
EPA 3060A/ 7196A- $ 60
EPA 3060A/ 7199 -$ 80
We can't rush any of this at this time- these methods (8151 and Hex Cr) take additional time in preparation. Quickest TAT is 10 working days.

Site Assessment Report June 25, 2020

1. 0 INTRODUCTION
On behalf of the City of Huntington Beach, EECEnvironmental ( EEC) has prepared this Site Assessment Report for the property located at 17642 Beach Boulevard, Huntington Beach, California ( subject property; Figure 1, Site Location Map). The purpose of the site assessment was to address findings of EEC's Phase I Environmental Site Assessment ( ESA) dated March 18, 2020. The Phase I ESA identified the following environmental concerns: potential use of pesticides/ herbicides and lead- based paint in connection with former agricultural and residential use of the subject property, and the lack of specific information related to the former use of the east half of the subject property as a storage lot in the 1960s. The Phase I ESA recommended soil sampling and a geophysical survey. The Phase I ESA and the site assessment were completed in connection with a proposed real estate transaction.

This report documents the methods, procedures, and results of the site assessment activities at the subject property. All work was completed in general accordance with EEC's April 2, 2020 proposal to the City of Huntington Beach ( EEC, 2020) and subsequent correspondence between the City of Huntington Beach and EEC. All work was performed under the supervision of a California licensed Professional Geologist( PG).

1. 1 Scope of Work
The completed site assessment activities included the following tasks:

Preparing a site- specific health and safety plan ( HASP) appropriate for the scope of work.

Contacting Underground Service Alert ( USA) a minimum of 72 hours prior to initiation of fieldwork.

Conducting a geophysical survey.

Advancing 9 soil borings to total depths ranging between 3 feet and 8 feet below ground surface bgs) and collecting soil samples.

Analyzing soil samples.

2. 0 BACKGROUND

2. 1 Site Description
The approximately 0.79-acre subject property consists of an undeveloped lot identified as Assessor Parcel Number ( APN) 167- 042- 09, located at 17642 Beach Boulevard in Huntington Beach, Orange County, California. A PhaseI ESAwas completed for the subject property on March 18, 2020 (EEC, 2020).

The Phase I ESA indicated that based on a review of historical aerial photographs, the subject property appeared to be used for agricultural purposes (row crops) from the 1930s to the 1950s and given this usage, it is possiblethat pesticidesand/or herbicideswere once usedonsite. Additionally, due to the date of construction of the former onsite residences ( 1930s), lead-based paint may have been used onsite. Further, during the 1960s, the east half of the subject property appeared to be used as a storage lot, but information was not obtained related to the specific use. During site reconnaissance for the Phase I ESA, uneven topography was observed on this portion of the subject property.

Based on this information, the Phase I ESA recommended soil sampling to assess for potential residual pesticidesandherbicidesfrom former agriculturaluse;to assessfor potential leadin the locationsof the S3506. 02T, Huntington Beach, CA 1 1V2k§
