MW-3 is located in an area of known contamination and shall be destroyed by removing all the contents of the well, as soil contamination was reported during installation of MW- 3 at 60 feet below grade surface (bgs) with TPHd at 69 mg/kg, and at 65 feet bgs with TPHg at 1.1 mg/kg; toluene at 0,018 mg/kg; ethylbenzene at 0.026 mg/kg; and xylenes at 0.058 mg/kg).
