sentinel well means a monitoring point established at a location between the leading edge of the solute plume and possible receptors (e.g., drinking water well, surface water body, sediment, public and private potable wells, well head protection areas, well fields and ground water discharge areas, surface water body, structures, and utility trenches that may be adversely affected by the release) to ensure that there will be time for other remedial actions to be taken if the plume migrates beyond predicted boundaries. Preferably a sentinel well needs to be a clean well.
