Biotic Zone definition

Biotic Zone means the interval in soil/sediment that corresponds to the highest level of biological activity. In terrestrial soil, biological activity is typically associated with soil invertebrates, plant/root production, and microorganisms; while in sediment the activity is associated with the macroinvertebrate community. This zone is generally related to the 0- 6” interval for sediments and generally 0-12” for soils, however, it may extend to deeper intervals in certain habitat settings or when burrowing receptors are present. While the NJDEP acknowledges that the depth of the biotic zone may vary, in accordance with Section 3.3 of the Technical Guidance for Site Investigation of Soil, Remedial Investigation of Soil, and Remedial Action Verification Sampling for Soil, samples should be collected from discrete 6-inch intervals.
