Which of the following strategies can help prevent water contamination?

Promoting community sanitation is an effective strategy for preventing water contamination because it helps maintain a clean environment, reducing the likelihood of pollutants entering water sources. Community sanitation initiatives may include proper waste management, sanitation facilities maintenance, and public education on hygiene practices. By ensuring that waste is disposed of correctly and preventing littering, communities can minimize the risk of harmful substances leaching into groundwater or flowing into rivers and lakes.

Healthy sanitation practices not only enhance the quality of local water supplies but also protect public health by reducing the spread of waterborne diseases. Community involvement in sanitation efforts can foster a sense of responsibility and encourage collective action towards maintaining clean water sources. This strategy stands in stark contrast to the other options, which could contribute to environmental degradation and water contamination.
