Wastewater analyses play a critical role in the protection of water resources and the sustainability of environmental health. These analyses are conducted to identify pollutants and chemical constituents within wastewater, determine the level of water pollution, and ensure compliance with environmental standards. Additionally, environmental protection laws and regulations establish the criteria by which these analyses are performed, encompassing the necessary conditions for water recycling and treatment.

The process of obtaining water samples is crucial for accurate results. Key factors to consider during sampling include the method of collection, cleanliness, storage conditions, and timing. Therefore, water samples must be collected by trained and authorized personnel.

Wastewater analyses are widely used in treatment plants, industrial facilities, municipal wastewater management, and environmental research. These analyses help evaluate the environmental impacts of water and guide necessary improvement measures. As a result, they contribute positively to both human health and the ecosystem.
