A few Twitter users posted photos showing the electric green water.

DC Fire and EMS responded to Broad Branch on Sunday morning because of calls from concerned citizens.
The green tint was the result of a dye test that water officials conducted Saturday along nearby Military Road NW as part of a project in Chevy Chase, DC Water spokesman John Lisle told News4.

The dye is harmless, a representative for the utility said.
