The head of an Ithaca-based environmental database firm says he believes remaining pollution from the old IBM-Endicott manufacturing complex remains a threat to public health.
Toxics Targeting president Walter Hang is expressing concern that people exposed to TCE - trichlorethylene - used by the company over the years are at increased risk of contracting Parkinson's disease.

Speaking on WNBF Radio on Monday, Hang said TCE is "one of the main contaminants at IBM-Endicott."
Hang said although the contamination at the manufacturing site was discovered 45 years ago "it's still not cleaned up."
Hang said TCE from the facility has affected 250 acres near where IBM had operated. He said the TCE "can come up inside buildings just like radon."

Toxics Targeting is launching what's billed as a "Parkinson's Prevention Campaign" to provide information to people who believe they may have been exposed to the chemical.

Hang said he's calling on New York Governor Kathy Hochul to take action to ensure that remediation action is taken at known TCE dump sites.
Hang called the governor's regulatory enforcement failure at the former IBM-Endicott site "shocking, irresponsible and unacceptable." He contends the extensive contamination that remains in the area threatens hundreds of homes with soil vapor intrusion.
