Sample Information and Description

Sample ID Element Example Entry Description Site Description DCW DuPont Chambers Works

Year 23 2023 Waste Location AWTF Alternate Waste Transfer Facility Excavation Area AC4 Area of Concern 4 (AOC4) Sample Interval BRM South Berm Area (BRM)

Sample Interval Description CB4 Represents soil from Excavation Cell B4 (CB4) Sampling Area P1 Stockpile 1 of Cell B4 Sample Type CB4P1C/G C-RCRA Composite Sample; G or no Descripter-UHC Hot Spot Grab Sample

Sub-Stockpile Sample Number 001/002 Stockpile/Sub-stockpile number of the above cell and/or stockpile

Sampling Notes:

1. All waste is from the AOC4 SBA area (AC4) on the former DuPont Chambers Works (DCW) FUSRAP site

2. Each combined stockpile represents aproximately 400-600 CY (1/2); Each sub-stockpile (1/001, 2/002, etc.) represents approximately 150-300 CY of waste

3. Stockpiles/Substockpiles are distinct sampling units and maintained as such until shipped unless consolidated due to common RCRA/UHC constituents

4. Composite (C) samples are representative of the entire stockpile and used for RCRA determinations

5. Grab (G) samples are taken in hot spot areas and representative of worst case chemically impacted soils

6. Excavation areas are distinct remediation cells separated by sheeting or physically isolated from other remediation cells
