Chemical hazards in drinking-water - beryllium
Rolling revision of the WHO Guidelines for Drinking-water Quality
Beryllium is included in the plan of work of the rolling revision of the WHO Guidelines for Drinking-water Quality.
Background
WHO has received correspondence noting that although the Guidelines for Drinking-water Quality state that beryllium is unlikely to be present in drinking-water, over the past 5 years in Europe, geological studies show concentrations ranging from <0.005 to 2.7 µg/litre (median 0.01 µg/litre) across Europe.
Expected end-product(s)

Progress to date
The Guidelines for Drinking-water Quality Working Group meeting (Geneva, 2005) agreed on a plan of work.
