2012 marks the bicentennial of the opening of the Fairmount Water Works, Philadelphia's claim to fame as the first large American city to provide safe water to its residents. Join us at the Fairmount Water Works Interpretive Center on Thursday, January 19 from 5:30 to 7:30 p.m. for a presentation on the history of water filtration in Philadelphia. PWD's Adam Levine and C. Drew Brown will use historical imagery to detail how filtration made the polluted waters of 18th-century Philadelphia safe to drink.
