The wives of four of the plaintiffs are seeking an additional $200,000 apiece in the civil suit filed Tuesday in the Oneida County Clerk's office.
The lawsuit names Holly Jones, 46, of Sherrill, and Robinson Aviation, Inc., of Oklahoma City, as defendants. The company formerly contracted with the county to provide air control and other services.
According to the lawsuit, which accuses Robinson of assault, several plaintiffs consumed the mixture of water, coffee and urine and became "physically ill."
The suit claims Robinson Aviation was negligent because it failed to fully screen employees and conduct routine performance examinations.
The spouses seek damages because they say their husbands "would not freely mingle in society with others because of the derision and jokes" made in public.
Two years ago, Jones was sentenced to 30 days in county jail. She pleaded guilty to a misdemeanor count of creating a criminal nuisance.
State police said Jones urinated on several occasions into a glass coffee pot used by other airport personnel and pilots. She was reportedly mad about being passed over for a promotion, officials said.
State police became involved after the tower manager reported a strong odor emanating from the coffee machine. The odor warned employees of a problem before any tainted coffee was used, police said. No sicknesses were reported.
Employees cleaned the coffee machine several times, but the odor never went away. Officials said a sample of a yellowish liquid was taken from the machine and sent to a lab for testing. The results revealed that the substance was urine.
State police then set up video surveillance above the coffee machine and caught Jones urinating into the pot, then pouring the urine into the coffee machine.
