  1. Pavillion Groundwater InvestigationPavillion Wyoming Phase I Sampling Results August 11, 2009

  2. Sampling Objectives • Determine if contamination is present in domestic wells • Determine contaminant characteristics • Determine potential impacts to public health and the environmennt

  3. CLP Lab Data SVOC + TICs VOCs + TICs Pesticides PCBs TAL Metals Process Data Validation Interpretation Relevance Select Wells and Sources for Further Investigation R8 Lab Data Low SVOC TICs Low VOC TICs TOF-MS PMBE Anions Water Chemistry Merge Data Sources Choose Tests/ Methods for Further Investigation Com Lab Data GRO DRO BAC-T Determine Relevant Data

  4. EPA R8 Lab: TICs

  5. VOC & SVOC TICs: Summary

  6. Methane Detections

  7. Summary and Interpretation of Results • Our results show most wells sampled have no apparent health concerns • 11 wells have insufficient data for us to assure well owners of no health concerns from drinking their well water (EPA is working with those well owners) • Potentially a connection between our results and oil and gas production activities. We cannot pinpoint any specific source at this time.

  8. Next Steps • Further Sampling for specific drinking water wells and potential sources • Meeting with stakeholders to determine the best way to approach the next sampling effort • Parallel issue: EPA will be talking with EnCana to evaluate and reduce any potential overall adverse impacts of oil and gas production.
