Petrolia residents remain under a boil order after a water pipe broke there yesterday.
Officials say the main water pipe burst near the city lake.
Petrolia Mayor Bill Holmberg says the boil order will be in effect until tests are done on the city's water, to make sure it's safe to drink without having to boil it.
He says he hopes to get those tests done tomorrow.
They began fixing that pipe late yesterday afternoon and their work was completed just before 6 p.m. Saturday.
City officials say they did not see any dirt go into the pipe, but just to be safe, they've put the city under a boil order until further notice.
