Slide 20: Gas Fingerprinting
Gas Fingerprinting 22 groundwater samples from 21 wells and 3 gas samples from the Harman well were collected: • samples submitted to IsoTech for compositional and isotopic analysis • gas concentrations varied in samples • 8 groundwater samples from 7 wells contained sufficient methane for stable is

Slide 23: Methane Isotope Composition
Methane Isotope Composition • Overlying strata are gas-bearing and this methane can be distinguished from Marcellus shale gas (Bradford & Susquehanna Co.). • Lycoming Co. also commercially produces gas from Upper Devonian (Shrewsbury Gas Field <10 mi. NW of Harman well). Fig. 6 from Molofsky et al.

Slide 25: Conclusions
Conclusions • Studied gases from Harman, Lewis 1H well are distinguishable isotopically and compositionally compared to gases from the area’s groundwater wells. • Range’s Harman, Lewis Unit 1H gas production well is not the source of methane gas in any of the 21 residential water wells studied.
Slide 26: Summary
Summary Multiple lines of evidence demonstrate Harman, Lewis 1H well gas is not the source of gas in area groundwater: - Integrity of the Harman, Lewis 1H well is confirmed - Methane existed in the area’s groundwater prior to drilling the Harman, Lewis 1H well – Overlying strata contain native gas,
