What is one common consequence of not properly filtering wastewater?

Not properly filtering wastewater can lead to the release of pathogens into the environment. Wastewater can contain various harmful microorganisms, including bacteria, viruses, and parasites, which can pose serious health risks to humans, animals, and ecosystems. If the filtration process fails to remove these pathogens effectively, they can contaminate water bodies, soil, and even drinking water supplies, leading to outbreaks of diseases. Proper filtration is essential to ensure that the wastewater is treated adequately before it is discharged or reused, thereby protecting public health and the environment.
