In which direction should the operation of a sanitary landfill be aligned?

The operation of a sanitary landfill should be aligned with the prevailing wind to minimize the potential for odors and airborne pollutants to affect surrounding areas. By positioning the landfill in alignment with the direction of the wind, any odor or airborne particulates generated during operation are less likely to be carried away from the landfill site, reducing the impact on nearby communities. This alignment also aids in controlling dust and other emissions, improving the overall environmental management of the site.

Properly managing wind direction in relation to landfill operation is critical for minimizing complaints and health risks associated with air quality. The other options suggest orientations that could allow for unpleasant odors and other emissions to drift into populated areas, potentially causing nuisance or health issues. Therefore, aligning operations with the prevailing wind is considered a best practice for environmental health and safety.
