Abstract
As natural gas has grown in importance as a global energy source, leakage of methane (CH4) fromwells has sometimes
been noted. Leakage of this greenhouse gas is important because it affects groundwater quality and, when
emitted to the atmosphere, climate. We hypothesized that streams might be most contaminated by CH4 in the
northern Appalachian Basin in regions with the longest history of hydrocarbon extraction activities. To test this,
we searched for CH4-contaminated streams in the basin. Methane concentrations ([CH4]) for 529 stream sites are
reported in New York, West Virginia and (mostly) Pennsylvania. Despite targeting contaminated areas, the median
[CH4], 1.1 μg/L, was lower than a recently identified threshold indicating potential contamination, 4.0 μg/L. [CH4]
values were higher in a few streams because they receive high-[CH4] groundwaters, often from upwelling seeps.
By analogy to the more commonly observed type of groundwater seep known as abandoned mine drainage
(AMD), we introduce the term, “gas leak discharge” (GLD) for these waters where they are not associated with
coal mines. GLD and AMD, observed in all parts of the study area, are both CH4-rich. Surprisingly, the region of oldest
and most productive oil/gas development did not show the highest median for stream [CH4]. Instead, the median
was statistically highest where dense coal mining was accompanied by conventional and unconventional oil and
gas development, emphasizing the importance of CH4 contamination from coal mines into streams.
