Spectra Energy says third-party soil and water tests have turned up no contamination from a massive natural gas pipeline explosion in western Pennsylvania last month.
The Pittsburgh Tribune-Review reports that the company earlier said that tests ruled out contamination to soil and surface water from the April 29 blast in Salem Township, 30 miles east of Pittsburgh.
The latest test results included samples from two water wells in the largely rural area. Spectra spokesman Creighton Welch did not identify the company that did the tests.
The explosion scorched 40 acres, seriously burning a man whose home was destroyed.
The federal Pipeline and Hazardous Materials Safety Administration has reported finding corrosion indicating a “possible flaw” In materials used to coat welded joints of the 30-inch pipeline installed in 1981.
