Officials: South Philly rowhome explosion caused by cracked gas main

PHILADELPHIA (KYW Newsradio) — Philadelphia city officials confirmed Thursday that the cause of the December explosion and fire at Eighth and Reed streets, which killed two people, was a leak from a cracked gas main under the street. Officials said they're not sure what caused the break, or if it's related to a series of water main breaks that have plagued the block since the incident — but neighbors confronted officials at the news conference and demanded answers.

Domenica Federico expressed the frustration of many residents on South Eighth Street, who say they are afraid to be in their own houses and worry that a recurring series of water main breaks in the street means some instability that could lead to another disaster.

"I pay taxes here. I'm a homeowner. Something is going on there," Frederico said. 

Harold Krakow lives one door away from one of the three houses that were destroyed in the explosion — but he hasn't been back since it happened.

"Next to us, we just heard that house might be compromised, so we could be the last house standing and we're not feeling confident at all about moving back. That's really the issue," he said. 

He and other neighbors came to City Hall for an update on the explosion and were not at all satisfied by the announcement that the gas leak was the proximate cause, and the root cause remains unknown.

They also said the city has been too slow to identify the cause of an unusual number of water main leaks since the explosion and whether they're related. Fire Commissioner Adam Thiel tried to reassure them.

"It is going to take time and I think all of the questions you are rightfully asking are going to be part of the investigation that is being performed by the Pennsylvania Public Utility Commission," Thiel said. 

He said hundreds of thousands of gallons of water were used to fight the blaze, and the street's structural integrity was compromised. 

.@ThielAdam: This is still a very active and dynamic scene. First priority is to go in and search for people. @MyPGW is working to shut off gas to the area. Fire has involved 3 or 4 buildings at this point; at least one has fully collapsed. pic.twitter.com/gpcpVz2Yc4

PGW Executive Vice President and acting COO Doug Moser said about 6,000 miles of the company's gas mains date back to 1900. It has a replacement program that recently replaced 35 miles of mains at a cost of $85 million.

That brought little comfort to neighbors, but city officials apologized and promised to be more responsive.
