Abstract

Dissolved-methane concentrations were measured in 87 drinking-water wells in the Appalachian Plateau Physiographic Province of Maryland between 2012 and 2014. The objectives of the study were to measure baseline dissolved-methane concentrations in well water in the region where natural gas from the Marcellus may eventually be produced, and (to the extent possible) evaluate factors associated with the occurrence and distribution of dissolved methane. Wells were sampled for dissolved methane, ethane, propane, and ethene; most samples were also tested for n-butane and isobutane. Field-measured parameters included pH, specific conductance, dissolved oxygen, alkalinity, chloride, and total hardness. The key results of this investigation are:
