Chalmers Knitting Mills was a historic factory building located at Amsterdam, Montgomery County, New York.

The addition was set at a near-right angle to the original section, giving the building an L-shaped footprint.

The mill produced undergarments and remained in operation under the Chalmers name until the founders' death in 1959.

The state Department of Environmental Conservation provided $1.9 million to clean up the contamination.
