if work proceeding under an approved Form 27: | N/A | | | | Spill Description: | | During plugging and abandonment activities at the Strear Sidney GU 1 wellhead, five (5) shallow soil vapor points (SVPs) were installed in the vicinity of the wellhead. On March 14, 2025, methane was detected with field screening equipment at SVP-01 and SVP-05. Soil vapor samples were collected from 5 SVPs using IsoTubes™ and an IsoTube™ sampling manifold in conjunction with the pump on a GEM 5000. The samples were submitted to IsoTech for gas composition analysis. Results from the gas composition analysis indicated the presence of thermogenic gas. An investigation into the nature and source of the soil gas is on-going. Additional details will be provided in a supplemental Form 19 Spill/Release report (Remediation No. 34638; Form 27 Initial Document No. 403711424). A topographic Site Location Map showing the geographic setting of the release is provided as Figure 1. | | |
