PVC and PE pipes are not contaminating the drinking water, the Danish EPA states
The doubt about plastic pipes’ suitability for drinking water has now been disproved
01-12-2005
The Danish Environmental Protection Agency has just published the most comprehensive study until now on any possible risk caused by plastic pipes used in drinking water supply. The study clearly shows neither problem with PVC nor with PE pipes.
The Danish EPA has carried through this new study because an article from the Technical University of Denmark (DTU) of 2002 showed that there were given off substances from some of the PE pipes examined. The pipes that DTU analyzed at the time were new pipes, and not pipes having been lying in the soil. Since it is not always so that analyzes of new pipes are showing the same results as analyzes of pipes in use, the authorities decided to analyze the PVC and PE pipes that are in the existing water supply net.
In
As for PVC pipes the report concludes that “emission of the examined substances from PVC pipes are less than the emission from PE pipes. This study along with studies carried through more recently has shown that there is a low emission of substances from PVC pipes in general.”
See the Danish EPA press release in connection with the publication of the report and see the whole report in Danish here - including a short summery in English.
