WESTLAKE, LA (KPLC) - Routine testing in a drainage system in Westlake has caused concern, but is not posing a danger to the public, according to officials.
The green tint to the water in the marsh area near the Calcasieu River is just underneath the I-10 bridge.
Westlake Police and OEP officials said that crews with Phillips 66 had permission to use the green dye to test the drainage in the area.
However, the public was not notified, causing some concern when people spotted the green water.
Officials said it is a non-hazardous, biodegradable dye.
The Hazmat report from the Louisiana State Police shows that Phillips 66 did alert state officials as early as Tuesday that the tests would be conducted.
The report says that the dye should dissipate in about six days.
