Key terms
- potable water: In Waste water treatment, potable water means water that is safe to drink. This matters in Using the Earth's resources and obtaining potable water because it supports the learning objective to compare the relative ease of obtaining potable water from waste water, ground water and salt water. Use potable water only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
- waste water: Water that has been used and contains contaminants, requiring treatment before release into the environment.
Common trap
Confusing Water Sources: Do not treat this as a general statement about waste water. Instead, answer by clearly linking the correction to compare the relative ease of obtaining potable water from waste water, ground water and salt water in Waste water treatment. This keeps the response inside Using the Earth's resources and obtaining potable water and prevents a vague or off-topic GCSE answer. The mistake to avoid is: students often confuse the ease of obtaining potable water from waste water with that from ground water and salt water, thinking they are equally easy to treat.
