Water Bureau Investigates Water Quality in Southwest Portland

Water continues to be safe to drink.The Portland Water Bureau continues to investigate the cause of total coliform bacteria in the drinking water system in Southwest Portland. 

Finding total coliforms in our water at this time of year is not unusual following warm summer temperatures and decreasing water demands. Total coliforms occur naturally in our environment. When they show up in our water, they are a good indicator to check our system for possible contamination or operational issues. 

What’s important to know is that the water continues to be safe to drink.  

The Portland Water Bureau has extensively sampled this area to test for E coli, a sign of fecal contamination. All of these samples have been negative for E coli. The Water Bureau also collects more than 240 routine water quality samples a month around the city to test for total coliforms and E.coli. To date, there have been no indications of fecal contamination in the water system. 

We will continue to implement operational actions to get this older water out of the system. The bureau will also continue to consult with State and local health officials. 

The Portland Water Bureau appreciates the patience of Southwest Portland customers while we ensure they continue to receive safe drinking water.
