Abstract: A soil sample containment device is provided which allows soil samples to be contained within individual sections of a soil sampler liner. The device includes first and second end caps for covering and sealing the respective ends of the soil sampler liner section. Each end cap has a structure for coupling with the opposite end cap for securing the end caps together. The coupling structure for each end cap includes a hook arm and an eye arm. The hook arm of the first end cap can be coupled with the eye arm of the second end cap to secure the end caps together over the ends of the liner section. A flexible sealing material is provided within each end cap for providing a compression seal between the end caps and the liner section. The liner sections can be formed of different lengths and different materials to accommodate different soil tests.
