Frequent Questions

Is it necessary to complete an entire site investigation to show that human exposures are under control?

No, human exposures can be considered "under control" if adequately protective controls are in place to prevent unacceptable exposures (i.e., cut pathways between humans and contamination) for the reasonably-expected worst-case conditions (in the un-investigated areas).
