if work proceeding under an approved Form 27: | 24708 | | | | Spill Description: | | During plugging and abandonment activities at the Thompson 25-6 wellhead, five (5) shallow soil vapor points (SVPs) were installed in the vicinity of the wellhead. On September 22, 2022, methane was detected with field screening equipment at SVP01 and SVP02. Soil vapor samples were collected from 3 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 a trace concentration of thermogenic gas. The results are attached to this report. An investigation into the nature and
source of the soil gas in on-going. The assessment details will be summarized in a supplemental Form 27 report (Remediation No. 24708; Form 27 Initial Document No. 403115154). A topographic Site Location Map showing the geographic setting of the release is provided as Figure 1. | | |
