The boil advisory for Columbia’s Thornbrook and Steeplechase subdivisions has been extended indefinitely.

On June 20th, the water pressure in those subdivisions again dropped below 20 pounds per square inch.

The drop happened again around four in the morning.

Columbia Water and Light is asking residents in the Thornbrook, Steeplechase, Creek’s Edge and Wyndham Ridge subdivisions to use the voluntary schedule they issued last week.
