A significant amount of an unknown chemical made it into an area sewer system, but Ithaca city officials say how it got there remains a mystery.
City officials confirmed Sunday that the chemical was either dumped through a building drain or manhole cover, and they say it happened either in the city or town of Ithaca, or in the town of Dryden.
It happened on November 23 or 24, according to city officials.
That chemical was toxic in the treatment process at the Ithaca Area Wastewater Treatment Facility, but no warnings were ever issued regarding water service or potential risks from the chemical dump.
City officials say the amount dumped was much more than what would’ve typically been found at a house.
