Officials test Traverse Bay for cyanide

Officials in Traverse City are trying to determine whether cyanide is seeping into Grand Traverse Bay from the construction site of an upscale hotel.

High levels of cyanide in groundwater have been detected. Jean Derenzy, a Grand Traverse County planning official, says the state is spending more than $600,000 to treat the groundwater before it's sent to a treatment facility.

The newspaper says that's on top of $1 million from the federal government for other cleanup activities.

Derenzy says the source of the cyanide is unknown, although there was heavy industry along Grand Traverse Bay decades ago. Environmental consultant Chris Grobbel says the aquifer containing the tainted water leads to the bay.

Hotel Indigo likely won't open by next spring.
