State one measure to control this pollution.
Topic: Control of water pollution
Answer
Industrial effluents and sewage should be TREATED in proper treatment plants before being discharged into any water body. (Also acceptable: strict enforcement of anti-pollution laws; reducing the use of chemical fertilisers and pesticides; public awareness campaigns.)
One measure, stated concretely. Vague good intentions ("we should not pollute water") earn nothing.
TREATMENT BEFORE DISCHARGE is the strongest single answer, because it addresses the cause shown in the picture rather than the symptom.
Measures fall into three kinds, and naming which you are giving shows understanding: TECHNICAL (treatment plants), LEGAL (laws and penalties) and SOCIAL (awareness and public pressure).
