      2.2.2 Gas Chromatography Detection and quantitation of methane was carried out on a Hewlett­ Packard 5710A gas chromatograph equipped with dual flame ionization detectors (FID). The column packing used was activated alumina, 60-80 mesh (1.8 m x 0.48 cm o.d.). The column temperature was held at 100°C.

      Methane dissolved in groundwater is not uncommon in many areas of Pa. It should not be evaluated the same as methane gas in or around a building. ~ 26 ----32 mg/l at atmospheric pressure, however, solubility in 15 water is proportional to pressure. Every foot of water exerts .43 psi or 2.31 feet of water is under 1 psi.
