Fixing the water main break that caused a drinking water crisis earlier this month and searching for the broken coupling that caused the problem has cost $572,000 so far, the Massachusetts Water Resources Authority says.
The number was revealed at an MWRA board meeting this morning, said Ria Convery, an MWRA spokeswoman.
Convery said the authority has been keeping track of the cost of putting the pipe back together and hunting for the coupling, but has told the contractor that it will withhold payment until an investigation determines what happened and who is responsible.
Workers continue to search for the coupling, digging in hot spots identified by ground-penetrating radar, she said.
The board also appointed the chairman of a panel that will look into the incident, choosing Wentworth Institute President Zorica Pantic.
The steel coupling connecting two 10-foot-diameter water mains failed on May 1 in Weston, causing a break that dumped millions of gallons of water into the nearby Charles River.
The break in the key water main bringing water east from reservoirs in the central part of the state to the Boston area forced the authority to switch to backup water. Governor Deval Patrick issued a boil-water order -- ordering nearly 2 million people people in Boston and dozens of other communities to boil water used for drinking or cooking. The order was lifted 2 1/2 days later, after the pipes were fixed.
