What are potential environmental impacts of improperly managed wastewater?

The potential environmental impacts of improperly managed wastewater primarily include pollution of water bodies, harm to aquatic life, and public health risks. When wastewater is not treated adequately, it can release harmful substances, including pathogens, heavy metals, and nutrients, into nearby water systems. This pollution can lead to eutrophication, which disrupts aquatic ecosystems, leading to the death of fish and loss of biodiversity. Additionally, contaminated water can pose significant health risks to humans, particularly if they come into contact with or consume polluted water, leading to diseases and health issues. The correct answer emphasizes these serious and interconnected effects on both environmental and public health.
