Spatial Bounds Clause Samples

Spatial Bounds. This study should seek to collect data on LA concentrations in duff and tree bark from locations within a two mile buffer just outside the NPL boundary. The study area should encompass the circumference of the entire NPL boundary, with the exception of the area east of Kootenai Falls. Sampling of this area will be completed as part of investigations specific to Operable Unit 7. Although it is not necessary that sampling locations for each medium (duff and tree bark) be co- located, to limit level of effort in the field, duff should be collected in close proximity to the trees that are selected to be sampled for tree bark.
