The field teams will also be responsible for packaging the soil sample jars for transfer to Baltelle Columbus Laboratory in Ohio. 5.2 The field teams will be responsible for generating the Chain-of-Custody form for each sample, and for shipping these with the samples to Battelle Columbus Laboratory. 6.0 Apparat us and M aterials 6.1 Materials 6.1.1 Glass sample j ar 6.1.2 Scrape (putty) knife 6.1.3 House/Building Characteristics Observation Survey (Form #2 or #3) 6.1.4 Large (15" x 15") lint-free laboratory tissue (example: Kimwipes, available from Kimberly-Clarke Corp., Roswell, GA 30076) D:\prjheds\ctepp\docssop220wpd April 11, 2000 ------- CTEPP 2.20 Version#: 1 Date: October 5, 1999 Page 4 of 5 6.1.5 Disposal latex gloves 6.1.6 Blue ice 7.0 Procedures 7.1 Confirm with the parent or day care center teacher about the child's outdoor play area. 7.2 Scrape up the top 0.5 cm of soil in an 0.095 m2 (1 ft2) area in the middle of the child's play area. 7.3 Use the scraping (putty) knife to pick up the soil sample and put it in the glass jar. 7.4 Store the glass jar in a cooler with blue ice until it is returned to the laboratory. At the laboratory, store the jar in a freezer at<-10°C. 7.5 Ship the jar by cooler with dry ice to Battelle Columbus Laboratory by FedEx. 7.6 In the event that there is no bare dirt or soil in the child's play area (e.g., only grass), collect the sample from the area around the house (e.g., sidewalk, driveway, garden). [Note: Also make notes about no bare dirt or soil was in the child's play area.] 8.0 Records 8.1 The sampling location will be recorded in the Field Notebook. 8.2 A Chain-of-Custody record will be used to document the sample collection and shipping. 9.0 Quality Control and Quality Assurance 9.1 The Field Notebooks will be reviewed and verified by the Field QA Officer, the Field Team Leader, and the Task Order Leader through internal field audits and quality control audits.
