1.0 Introduction

This report summarizes the results of a bulk paint chip sampling survey for lead in airfield striping on Travis AFB, Fairfield California.

The bulk sampling of airfield striping throughout was conducted during April 23 through May 3, 2018. The purpose of the survey was to determine the concentrations of lead throughout the before removal and repainting.

SCA representatives involved in the survey, and their technical certifications, include:

2.0 Methodology

2.1 Sampling & Analysis

The airfield was divided into 9 areas based on a phasing diagram provided by AECOM. SCA’s surveyors attended an airfield safety training session, along with obtaining decals for vehicles accessing the airfield. During sampling, SCA was always accompanied by an airfield escort, who was on radio communication with the air control tower, to ensure maximum health and safety for the survey team, and the flights using the airfield.

SCA collected a total of 450 chip samples from the airfield, averaging 50 per each of the 9 areas.

Each sample was collected using a chisel and hammer, with the sample container labeled as follows:

• Phase – sequential # - color coding.

• For example, sample ID: 210Y represents a sample collected in the Phase 2 area; it was the 10th sample and yellow in color.

The same sample ID was immediately recorded on the aerial photograph on an iPad tablet computer. A photograph of the sample location, marked with the sample ID on an erasable board, was also taken.

Samples were sent via overnight services at the end of the week accompanied by Chains-of- Custody (COC).

Paint samples were submitted to REI Environmental, Inc. laboratory for analysis of lead. Paint samples were analyzed in accordance with the EPA Method SW846 3050B / AA 7420.

5.0 Limitations and Exclusions

SCA warrants that this survey was performed using due care and state of the art techniques.

Beyond this, SCA does not warrant or guarantee the survey. Despite the care exercised, some materials may not have been identified, or may have been incompletely identified. This condition may occur due to renovations or original construction practices that concealed older materials, and/or visually similar materials with different compositions.
