What would be a likely characteristic of wastewater with a high level of solids?

Wastewater with a high level of solids is likely to have a strong disagreeable odor. This increased concentration of solids can originate from various sources, including organic materials, food waste, or sewage. Such materials can decompose and produce odors due to anaerobic breakdown processes, especially when the wastewater is stagnant or improperly treated. The presence of these solids contributes to the overall smell, often making it offensive and unpleasing.

In contrast, characteristics like being clear and odorless are more commonly associated with high-quality or treated effluents, where solids have been removed effectively. A pleasant smell would typically not be found in wastewater with a high concentration of solids, as organic matter often gives off foul odors during decomposition. Bright color is also not indicative of the solids themselves, as wastewater can be dark or murky due to high solid contents, rather than vibrant. Thus, the strong disagreeable odor is a direct consequence of the breakdown of organic solids present in high concentrations.
