Organic substances:
Sewage contains various organic substances such as human waste, food scraps, oils, and other biodegradable materials. These organic compounds can contribute to water pollution and can be harmful to aquatic life if not properly treated.

Inorganic substances:
Inorganic substances like heavy metals, chemicals, and other non-biodegradable materials may also be present in sewage. These substances can have toxic effects on the environment and can pose risks to human health if they enter water sources.

Nutrients:
Sewage often contains nutrients such as nitrogen and phosphorus, which can promote the growth of algae and other aquatic plants. This can lead to eutrophication, a process where excessive nutrient levels cause harmful algal blooms and deplete oxygen levels in the water, harming aquatic ecosystems.

All of the above:
The impurities present in sewage can consist of a combination of organic substances, inorganic substances, and nutrients. Therefore, the correct answer to the question is 'All of the above'. Proper treatment of sewage is essential to remove these impurities and protect the environment and public health.
