  • Concentration of uranium, a radioactive substance, up to 60 micrograms per litre (millionth of a gram per litre or µg/l) in drinking water was entirely safe.
  • In 2021, the Bureau of Indian Standards (BIS) announced a new limit of 30 µg/l, in line with recommendations of the WHO.
  • Finland and Slovakia — two nations with considerable amounts of uranium consumption — have prescribed safety limits of 100 and 350 µg/l respectively.
  • Another uranium-rich country, South Africa, has a limit of 70 µg/l.
  • The limits in countries like Canada and Australia that have the largest deposits of uranium among others are 20 and 15 µg/l, respectively.
  • Germany, which does not have uranium, has even lower limits.
