Potable Water - GCSE Chemistry Definition

Reviewed by: Richard Boole

Published

Potable water is water that is safe to drink or use in cooking. It contains low levels of dissolved salts and microbes, making it free from substances that could be harmful to human health.

To make water potable, it is treated using methods such as:

  • Filtration – to remove solid particles

  • Chlorination – to kill harmful bacteria

Potable water is not the same as pure water (which contains only H2O molecules), but it is clean and safe for everyday use. In GCSE Chemistry, potable water is studied as part of water treatment and resources.

Richard has taught Chemistry for over 15 years as well as working as a science tutor, examiner, content creator and author. He wasn’t the greatest at exams and only discovered how to revise in his final year at university. That knowledge made him want to help students learn how to revise, challenge them to think about what they actually know and hopefully succeed; so here he is, happily, at SME.
