Additional Groundwater Investigation for 1,4-dioxane Commences

USEPA (EPA) approved the Groundwater Investigation Work Plan on 27AUG15 for further delineation of the contaminant 1,4-dioxane. The investigation will include installation of additional monitoring wells, comprehensive groundwater quality monitoring to define the extent of the 1,4-dioxane plume and water level monitoring. EPA is considering accelerating this portion of the proposed remedy and performing it as a Non-Time-Critical Removal Action (NTCRA) rather than as part of the overall remedy. Crews mobilized to the site and began well installation today, 1SEP15.
