Which practice could lead to contamination of land and water by human waste?

• A. Rapid construction of latrines
• B. Delayed latrine construction
• C. Composting toilets
• D. Improved sewage treatment

Answer: (A)

The main point is that sanitation facilities must be planned, properly sited, and well built to contain human waste. When latrines are constructed rapidly without careful design and assessment, important safeguards can be skipped. You might end up with pits that aren’t lined or sealed, walls or slabs that leak, and waste that isn’t safely contained. If pits are placed too close to water sources, flood-prone areas, or surface water, fecal material can infiltrate groundwater or run off into rivers and streams. In short, haste undermines containment and maintenance, creating pathways for human waste to contaminate land and water. Composting toilets and improved sewage treatment, by contrast, are designed with containment and treatment in mind, reducing the chance of contamination. Delaying latrine construction can also pose risks through open defecation, but the specific contamination risk highlighted here comes from failing to properly design and site latrines due to rapid, unplanned construction.
