Several environmental monitoring events occurred over the past six months. Groundwater sampling occurred during the 3rd and 4th Quarters (August and October) of 2023. A revised air monitoring work plan was submitted on October 16, 2023. Passive indoor air monitoring was conducted during late November. In addition, sub-slab samples were at 13 locations. The results indicated consistent results. Finally, a sub-slab depressurization pilot test was conducted in early December 2023. Information collected from this test will be used to inform the design of the sub-slab depressurization system.
