Preliminary Findings • Methane occurs naturally and highly variable: ‣ Spatially and temporally ‣ Weather ‣ Man‐induced changes (water well pumping) • Single pre‐drill baseline methane sample may not represent the full range of natural variability • Natural methane levels (headspace and dissolved) may be influenced by pumping or water level fluctuations • Water level declines (pumping or natural) may increase natural methane headspace concentrations • Natural methane concentrations may vary seasonally
