BROKEN ARROW, Oklahoma -- Water sample tests performed this week show there is no problem with the City of Broken Arrow's water supply, according to city spokesperson Stephanie Higgins.

On Monday, new tests were done at the area where there were E. coli-positive samples last week. They showed no contamination.

"The City is waiting to see if the Oklahoma Department of Environmental Quality will provide any additional requirements for this incident," Higgins said.

"If the City receives a requirement from ODEQ for additional actions, the City will take the required action and notify residents."

Earlier this week the City reported that the technician who processed the water samples that tested positive for E. coli may have contaminated the water before going home sick. Follow-up samples have all come up clear.
