Is your tap water safe? Mostly. The sewage is another story

How a story is made

Our standards · Corrections

  1. Every figure names its sourceOfficial figures come from Gazettes, regulators’ decisions and department reports, each checked against the page it is printed on. Figures measured from space or worked out by a weather model say so.
  2. Code does the sumsEvery number in a story is worked out from the data. None is typed in.
  3. A person approves itAI helps draft the words and voices the films. A person reads and checks every story first.
  4. Kept as publishedA story keeps the data it was written from. A fix is a dated correction at the top.
