Synagro's Bill Massa in the Grossest 'Undercover Boss' Yet [Video]

This week's episode has to be the oohiest, gooiest, grossest, most disgusting 'Undercover Boss' ever. But it's also the greenest, according to Bill Massa, president and CEO of Synagro, the nation's largest wastewater treatment corporation.

Although his company processes waste, he says the work is anything but. "Most people make widgets. We clean environments. We have a very important impact. In the old days, this would have been dumped in the ocean or gone into landfill. We're recycling and reusing. It's a dirty job, but we're a very green company," he told AOL Jobs.
