What kind of public health risk is linked with improperly treated water?

Improperly treated water is directly linked to waterborne diseases, which are caused by pathogens that are transmitted through contaminated water sources. This can include bacteria, viruses, and parasites that thrive in unsanitary conditions. When water is not treated correctly, these harmful microorganisms can lead to infections and illnesses such as cholera, giardiasis, and hepatitis A among others.

Maintaining proper water treatment practices is essential for safeguarding public health and preventing outbreaks of diseases that can spread rapidly within communities. While dehydration can be a consequence of these diseases, it is not the primary health risk associated with improperly treated water itself. Other options, such as soil contamination and increased food spoilage, do not directly stem from the condition of water being treated or not treated properly. Thus, the specific connection between improperly treated water and the onset of waterborne diseases makes this the most accurate choice.
