The Calgary Fire Department’s Hazardous Materials Response Team was called out on Wednesday morning after paint was discovered in the sewer system.

Crews were called to the 3000 block of Bowwood Dr. N.W. at about 9:00 a.m. and found about five gallons of paint spilled into the sewer.

There is some concern as the sewer is close to the Bow River.

Firefighters were able to contain the spill and prevent three gallons of the paint from entering the river.

Alberta Environment officials are monitoring the situation.
