C rews are still trying to determine the source of petroleum leaking into the canal.
Officials had expected to make some headway earlier this week, but heavy rainfall over the weekend and on Monday and Tuesday made locating the leak more difficult.
National Vacuum Emergency Response Spill Control was expected to resume its search yesterday.
The leak was first reported around 8 a.m. on Monday, April 16, in an area near the public boat launch on Skenesborough Drive, just south of the Canal Corp. Visitor’s Center.
After finding the leak, officials contacted the state Department of Environmental Conservation.
They found the substance was coming from a storm drain about 30 feet north of the boat launch It’s believed the substance was fuel oil because it had a pink hue, but officials haven’t verified that.
Containment booms were set up around the drain and just north of lock 12. Officials said they believe the booms were effective in preventing the fuel from entering Lake Champlain.
The size of the leak is unknown although officials have described it as more of a “nuisance” than a major spill.
Crews were able to narrow the search area to Broadway but have yet to pinpoint the precise origin.
Officials have said the leak has not entered the waste water treatment facility or municipal drinking water.
The public boat launch on Skenesborough Drive remained closed as of Tuesday.
