Spill Description:
On 9/17/2025, the potential presence of impacted material(s) was identified via hydrocarbon odor and hydrocarbon staining during the decommissioning at the ADAMSON 5, wellhead, sample: WH01-W located at the wellhead. The volume of potentially impacted material(s) is not currently known. Out of an abundance of caution, the operator is submitting notification within 24 hours of the discovery of the potential presence of impacted material(s) soil. Initial soil sampling is underway to determine whether any constituents are present at levels in excess of Table 915-1 standards. Groundwater was not encountered during decommissioning activities.
