Decades old water piping made from asbestos cement is starting to degrade – but what does it mean for human health?

Hundreds of thousands of miles of pipes made from asbestos cement deliver drinking water to people around the world, but are reaching the end of their lifespan and starting to degrade. Scientists are now debating whether this could pose a risk to human health.

“The water pipe burst on the top of the hill and flooded into the gas network,” remembers Alan Walker, owner of the Village Stores in Stannington, a suburb of Sheffield on the edge of the Peak District in England. “By the morning, people were turning on their gas hobs and water was coming out. It was one of the worst winters we had. We were one of the last houses to be reconnected, 13 days later.”

He is recalling an incident from December 2022. The burst water main affected more than 3,000 homes, and around 10,000 people in Stannington. More than a year on, it should be just a bad memory of a cold and unpleasant winter. But the water burst highlighted another nagging concern.

      To be more specific:

      Asbestos is a known carcinogen to humans, meaning it is capable of causing cancer. When asbestos fibres become airborne and are inhaled, they are known to lodge in the lungs and other parts of the airways, where they can cause scarring, inflammation, asbestosis – an inflammatory condition leading to permanent lung damage – and cell damage that lead to cancers, including mesothelioma, an incurable cancer of the lining that covers organs such as the lungs. For decades, however, the risk from swallowing asbestos has been thought of as small as most fibres were assumed to pass through the gut and be expelled in faeces.
