Urban Tree Deaths Are Linked to Leaks from Gas Pipes Below Streets

"A new study finds dying trees are 30 times more likely to have been exposed to methane-contaminated soil, confirming long-held suspicions that gas leaks kill plants."

"Natural gas leaks from underground pipelines are killing trees in densely populated urban environments, a new study suggests, adding to concerns over such leaks fueling climate change and explosion hazards.

The study, which took place in Chelsea, Massachusetts, a low-income immigrant community near Boston, also highlights the many interrelated environmental challenges in a city that faces high levels of air pollution, soaring summer temperatures and is now beset by one of the highest coronavirus infection rates in the nation.   

Dead or dying trees were 30 times more likely to have been exposed to methane in the soil surrounding their roots than healthy trees, according to the study published last month in the journal Environmental Pollution."
