Which of the following contaminants might be analyzed in a water sample?

The correct response highlights the significance of biological pollutants within the context of water quality analysis. Biological pollutants encompass a wide range of harmful organisms such as bacteria, viruses, parasites, and algae that can jeopardize human health and the environment. Analyzing for these contaminants is essential in ensuring safe drinking water and protecting aquatic ecosystems.

In the context of water sampling, it is vital to assess the presence of these biological contaminants because they can lead to waterborne diseases and other health issues if not adequately treated. Monitoring for biological pollutants is a standard practice in environmental testing and public health initiatives.

The other options do not appropriately represent the types of contaminants analyzed in water samples. Physical matter may refer to sediments or debris but neglects the critical aspect of biological and chemical pollutants. The notion of political pollutants is not a valid type of contaminant in water testing, as it mischaracterizes the nature of contaminants assessed in water quality. Ignoring all contaminants is contradictory to the goals of water quality monitoring, which aims to detect and manage various harmful substances. Thus, focusing on biological pollutants provides essential insights into the safety and quality of water samples.
