Mapping CVM/VCM pollution risks across Europe
A collaborative platform to document and track vinyl chloride monomer (VCM) in European drinking water networks.
VIEW THE MAPWhat is VCM?
The issue
Classified as a definite human carcinogen (Group 1) by the IARC, it is linked to risks of hepatic angiosarcoma and hepatocellular carcinoma. Vinyl chloride monomer (VCM) is a highly carcinogenic compound that can contaminate drinking water through aging PVC pipes.
Why it matters
Millions of kilometers of PVC piping are installed across Europe, and a significant share is nearing end of life. Data transparency varies widely between countries, making it hard to assess population-level risk with precision.
