Think of small pits as one or more areas of a larger pit and sample accordingly. Large facility impoundments, typically, receive the full spectrum of E&P wastes, which can be broadly classified into three major groups:
1. Weathered drilling fluids and drill cuttings from past operations
2. Recent spent drilling wastes reflecting newer formulations and∕or
3. Tank bottoms, and other produced liquids and sludges
Impoundments source variability, for example, size, and natural segregation of materials with depth and distance from the point of discharge, presents a challenge for obtaining representative samples. Representative samples are fundamental for characterization of pit content...
