Which of the following strategies is effective in preventing water contamination?

Proper waste disposal is a fundamental strategy for preventing water contamination. When waste materials are disposed of correctly, it minimizes the risk of harmful pollutants entering water sources. This includes practices such as recycling, reducing overall waste generation, and using designated landfills that are designed to contain pollutants. Proper waste management practices ensure that contaminants do not leach into groundwater or runoff into surface water bodies, thus protecting the quality of water available for drinking, recreation, and ecosystem health.

In contrast, increased water extraction can lead to depletion of water sources and may concentrate contaminants, while industrial waste dumping directly introduces harmful substances into the environment. Ignoring pollution control measures can exacerbate contamination issues, leading to long-term damage to water systems and public health hazards. Therefore, effective waste disposal plays a critical role in safeguarding water quality and ensuring a sustainable water supply.
