Methane in the Creek: How Streams Can Reveal Hidden Gas Leaks

A small creek can carry clues about big questions: energy, climate, drinking water, abandoned mines, old wells, and how communities notice changes in places they know well. In this episode, Waterlines follows researchers and volunteers across the northern Appalachian Basin as they use stream water to look for methane, a powerful greenhouse gas that can also change water chemistry underground. The surprise is not that every stream is full of methane. Most were not. The story is about the few places where groundwater seeps deliver methane into streams, and how those seeps can point to coal mines, old oil and gas wells, or newer gas development. We unpack the field methods, the limits of what stream sampling can prove, and why the authors propose a new term: gas leak discharge, or GLD, a cousin to the better-known abandoned mine drainage.
