What can be a consequence of inadequate wastewater treatment?

Inadequate wastewater treatment often leads to the release of pollutants and pathogens into waterways, which directly contributes to water pollution. When wastewater is not treated properly, harmful substances such as bacteria, viruses, heavy metals, and nutrients (like nitrogen and phosphorus) can contaminate water bodies. This pollution can have serious health implications for humans and wildlife, increasing the risk of diseases and harming ecosystems.

For instance, human exposure to untreated or partially treated wastewater can result in gastrointestinal diseases, skin infections, and other health issues. In addition, water bodies receiving contaminated wastewater may suffer from eutrophication, a process where excess nutrients lead to excessive algae growth, depleting oxygen levels and harming aquatic life. This cycle highlights the critical importance of effective wastewater treatment methods to protect both public health and the environment.
