The paper manufacturing industry would most likely contribute the greatest volume of wastewater to a POTW or receiving stream.

Explanation:
The main idea is that wastewater volume to a POTW is driven by how much process water a plant uses. Paper manufacturing requires enormous amounts of water for pulping, washing, rinsing, cooling, and other steps, so the total flow of wastewater is very large. Even if other industries might have higher pollutant concentrations (like BOD or TSS) or more acidic water (low pH), those factors describe strength or chemistry, not the total volume. Therefore, the paper industry typically contributes the greatest volume of wastewater to a POTW or receiving stream.
