COLUMBIA, Mo. -

Columbia's water supply could taste and smell different this week due to Columbia Water and Light's disinfecting process set to begin Tuesday.

CWL will change the process from using chloramines to free chlorine. The change is recommended by the Missouri Department of Natural Resources.

The water quality will be the same and will meet all EPA standards for the disinfection process.

Customers may notice a slight chlorine smell during the first few days of the switch. 

The Columbia Fire Department will begin testing fire hydrants on Friday for adequate water flow and pressure.

Customers might notice lower water pressure if they live near a fire hydrant. Sediment in pipes could be stirred up, causing water discoloration.

Water will run clear again after running for a few minutes and will be safe for consumption.
