Big Dig whack-a-mole: plug-a-leak

This headline in the Boston Globe is belied in the first paragraph: "Study sees progress in filling Big Dig leaks"

Construction crews have plugged hundreds of Big Dig leaks, but the tunnel system is still on pace to collect and pump out the same amount of water this year as it did in 2006, according to a study presented to the Massachusetts Turnpike Authority board yesterday.

So fewer "leaks" but just as much water. This is "progress?"
