Highlands volunteer firefighters went to a Highlands-area flood canal around 10:15am Sunday after receiving calls about an oily residue in the water.
Firefighters then found a leak coming from the ZXP Technologies facility in the 400 block of East Wallisville.
According to officials, ZXP Technologies is a lubricant mixing and packaging facility.
The firefighters requested assistance from the Harris County Hazardous Material Response Team, Harris County Pollution Control and the Texas Commission on Environment Quality in order to contain the discharge, which was flowing toward the San Jacinto River.
"We are working to contain the spill but due to the high flow of water in the canal the spill is not completely contained at this time", Captain Richard Lawhorn with Harris County HazMat said in a release Sunday. "There is no threat to the public at this time and clean up will begin shortly to try and minimize the effects on the waterways."
ZXP Technologies is cooperating with the environmental agencies and taking the necessary measures to clean up the spilled materials.
A full investigation into the cause of the spill is underway.
