]In the early 20th century, there were new roads, rails, and an underground system delivered gas to buildings around New York.
More than 100 years later the landscape has drastically changed — but some of those exact same mains are still delivering our gas today.
“That infrastructure is way past its service life, which is dangerous,†natural gas expert Mark McDonald said.
McDonald, who investigates gas explosions, said aging mains like the ones we have in the northeast are at greater risk for cracks and ultimately leaks.
He pointed to a string of accidents across the country, the largest of which happened in Northern California in 2010, it killed nine people and destroyed property.
“Her house was at the epicenter where the gas line exploded,†Kimberly Archie said.[/quote]
