Question
Why is it important to treat industrial waste water before it is released into the environment?
Answer
It is important to treat industrial waste water to remove harmful substances that can pollute water bodies, harm aquatic life, and pose risks to human health and the environment.
Explanation
A strong answer should directly address the approved learning objective to explain that industrial waste water may contain organic matter and harmful chemicals. This question belongs to Waste water treatment within Using the Earth's resources and obtaining potable water, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to waste water, and keeps the wording specific to AQA GCSE revision.
Common mistake
Confusing Organic Matter with Harmful Chemicals
Students often think that all organic matter in industrial waste water is harmful, overlooking that some organic matter can be benign or even beneficial.
Clarify that while industrial waste water may contain harmful chemicals, not all organic matter is harmful; some can be naturally occurring and non-toxic.
