Lead Reduction Test Results
NMCL (the Berkey manufacturer) has released the latest round of test results for the removal of lead from drinking water. The Black Berkey water filters were found to remove lead to a level of more than 99%.
Lead is an insidious contaminant as it can be neither tasted, smelt or seen. Fortunately the incidence of lead poisoning has declined in the UK as it is illegal to use lead solder or pipes in systems used for drinking water. However in older buildings (pre 1970) lead piping and solder can still be present. The water flowing through these systems can pick up lead particles which are then ingested.
