KITTERY — An employee at the Portsmouth Naval Shipyard received an electric shock while working in a pump well.

Deborah White, a spokeswoman for the shipyard, described the shock as minor. She said the employee was walking, but taken to a nearby medical facility as a precaution.

A pump well is where pumps used to dewater the dry dock are kept, said White.

She said there’s an ongoing investigation into the incident. White didn’t have more information about the employee.
