Which of the following describes domestic wastewater as it leaves a home?

Domestic wastewater as it leaves a home is typically characterized by being fresh, light in color, and containing dissolved oxygen. The water is often relatively clean and may still retain some of the qualities of the fresh water it originated from, particularly in terms of its lighter color. The presence of dissolved oxygen indicates that there are still some viable microorganisms and that the water has not become overly contaminated yet.

The characteristics of domestic wastewater at this stage suggest that it has not been subjected to significant decomposition processes, which would be expected if it were further along in the wastewater treatment cycle or had been mixed with other contaminants. This aligns well with the selection, as it accurately captures the more pristine condition of wastewater at the source, prior to treatment or significant degradation.

The other options involve descriptions of wastewater that are typically found downstream, after it has undergone various changes and degradation processes. These processes result in characteristics such as darker colors, thicker consistency, strong odors, or high turbidity, which occur as organic matter decomposes and pollutants accumulate.
