New test results show E. coli levels in the creek at Broken Arrow's Sieling Park have dropped significantly, so the city says it has reopened the park.
Earlier this week, the city said a subcontractor working north of the park caused a sewer leak that contaminated the creek.
The park is located in the 500 block of West Iola.
City crews cleaned up sewage that had pooled in the creek. They also added fresh water to help had pooled dilute the contamination.
Broken Arrow says the contractor has agreed to pay for repairs to the damaged sewer line.
