The health impact of living near a natural gas leak

The BBC spoke to UC College of Arts and Sciences Professor Amy Townsend-Small who has been studying the national problem of leaking and abandoned wells across the country.

"The highest concentrations of these non-methane hydrocarbons are in gas at wellheads, which also have the highest emission rates," Townsend-Small told the BBC.

Millions of Americans live within a mile of an orphaned oil or gas well or abandoned coal mine, according to the U.S. Department of the Interior. These sites are notorious for creating air and water pollution.

Congress set aside $4.7 billion in President Biden's Infrastructure Law to inventory and cap abandoned oil and gas wells. The initiative is expected to help address the escape of methane, a greenhouse gas that is a key driver of climate change.

In a study published last year in the journal PLOS Climate, Townsend-Small recommended a proposal to cap "marginal" or low-producing wells, many of which have also been found to be leaking.

She found that these marginal wells leak methane at a disproportionate rate compared to their meager production of oil or natural gas.
