Holtrachem Cleanup 

It’s all part of the effort to clean up the former Holtrachem plant in Orrington.

The question is whether to remove mercury downstream from the plant, or let the river flush the pollution away naturally.

Earlier this year, a judge agreed with a team of researchers who said the mercury pollution in the lower part of the river did in fact pose a threat to the health of humans and wildlife.

From the 1960’s until it closed in 2000, the plant used mercury to produce chemicals for the paper mills and other industries.

The study is being paid for by the corporation which used to own the plant.
