When sewage is not treated properly, it can contaminate water supplies and soil.<\/p>\n Fresh sewage is typically clear and has a slight odor. However, it can quickly become stale if it is not treated or disposed of properly. This is because the bacteria and viruses in sewage start to multiply and produce gases that give off a foul odor.<\/p>\n The time it takes for fresh sewage to become stale depends on a number of factors, including the temperature, the amount of sunlight, and the presence of oxygen. In general, sewage will become stale within two to three hours if it is not treated or disposed of properly.<\/p>\n Option A: One hour.

This is too long of a time for fresh sewage to become stale.<\/p>\n Option D: Six hours.
