Final answer:
Option (A), Wastewater treatment focuses on removing solids and reducing microbial loads, not on detecting each pathogen.
Step-by-step explanation:
It's false that wastewater treatment facilities employ methods designed to detect each pathogenic organism that may be present in a given sample. Instead, the facilities focus on removing organic matter, nutrients, and reducing the overall microbial load.
After primary treatment, if you analyzed wastewater, you would notice that much of the dissolved solids have been removed. However, harmful bacteria and other biological agents might not have been completely killed or removed at this stage, and the water is certainly not potable.
