👉 The worst fluid, in terms of general quality and impact, is often contaminated water. It can contain harmful bacteria, viruses, parasites, and various chemicals or pollutants that pose serious health risks. These contaminants can lead to waterborne diseases such as cholera, dysentery, and typhoid fever, making it extremely dangerous to consume. Unlike purified or treated water, unfiltered and untreated water lacks the necessary filtration and disinfection processes, rendering it unsuitable for drinking or even safe for cooking.
