Site Characterization Work Plan for the Gnome-Coach Site, New Mexico. Nevada Environmental Restoration Project

摘要

The purpose of this environmental investigation of the Gnome-Coach Site is to collect data of sufficient quantity and quality to establish current site conditions and to use the data to identify and evaluate if further action is required to protect human health and the environment and achieve permanent closure of the site. This investigation utilized available data and documented historical knowledge to the extent possible. Existing subsurface site information will be evaluated and migration of contaminants from the test cavity and tracer test area will be modeled to establish contaminant fate and transport. The subsurface modeling and risk evaluation will result in the potential refinement of the existing compliance boundary that defines the area where subsurface intrusion restrictions are applied.
