That data is still from 2009 though, but sadly there doesn't seem to be a newer statistic. Since that time many changes were made to push for the removal of old lead piping in the EU.

Anyway the threshold for lead in drinking water in the EU is 10ug/L since 2013.
Since 2020 a regulation has been in effect with the goal to have less than 5 ug/L drinking water at the consumer until 2036 everywhere in the EU.

The US has a threshold of 15 ug/L.
