BATON ROUGE (AP) — More than 100 abandoned oil wells, which can leak cancer-causing chemicals and threaten the environmental health of an area, in Louisiana have been plugged during the last two months, Gov. John Bel Edwards announced Thursday. There are more than 4,500 “orphaned wells” in Louisiana, a number accelerated by downturns in the prices of oil and gas in recent years that put financial strains on fossil fuel companies and their ability to maintain their sites or their businesses. Many times the owners of the sites can’t be found, have gone out of business or otherwise can’t be made to pay, according to the Louisiana Department of Natural Resources.
