Spill Description:
On 8/28/2025, Bernhardt 21-1 wellhead decommissioning activities were completed. During the completion of the activities, no potential presence of impacted material(s) was observed/smelled. Consistent with Rule 912, samples were collected and analyzed to determine whether any constituents are present at levels in excess of Table 915-1 standards. Final laboratory analytical results received on 9/24/2025 indicate that soil samples, WH01@5’ and WH01-E@4’ discovered at the wellhead excavation area, exceeded ECMC Table 915 standards for 1-Methylnaphthalene at 0.0137 mg/kg and 0.0119 mg/kg, respectively. Groundwater was not encountered during decommissioning activities.
