Spill Description:
On 10/14/2025, BLEHM 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 were present at levels in excess of Table 915-1 standards. Final laboratory analytical results received on 11/24/2025 indicate that soil sample WH01, discovered at the wellhead exceeded ECMC Table 915 standards for 1-methyl-naphthalene at 0.0075 mg/kg. Groundwater was not encountered during wellhead decommissioning activities. This location is within 300 feet of waters of the state.
