BOCA RATON, Fla. (AP) - An environmental advocacy group is raising a stink, accusing the Boca Raton wastewater management system of improperly disposing its wastewater.

Public Employees for Environmental Responsibility, which filed a complaint with the Environmental Protection Agency on Thursday, claims the city spilled 25 million gallons of treated wastewater into a canal in 2006.

The group is asking the EPA to investigate that incident and a dozen other alleged infractions.

Boca Raton Assistant City Manager Mike Woika said the significance of some violations had been inflated.
