Suggest various ways by which water pollution can be controlled.
• Domestic wastewater should be treated properly, and all harmful substances should be removed from it, so it can be reused for flushing toilets and gardening.
• Use bio-pesticides (natural pest control) instead of chemical pest control.
• Use compost made from cow dung, garden waste and kitchen waste as a fertiliser.
• Water released from industries should be treated before being discharged or recycled for industrial purposes.
• Use detergents that are biodegradable and avoid those that contain toxic chemicals.
• Wear clothing that is made from natural fibres such as cotton and avoid wearing synthetic fibres such as nylon, polyester etc.
• Do not throw waste such as plastics into water bodies. Always separate your waste into recyclable, non-recyclable and biodegradable so that it does not cause pollution.
