👉 Bad fluid refers to water or other liquids that are contaminated, polluted, or otherwise of poor quality. This can include substances like chemicals, heavy metals, bacteria, viruses, or other harmful contaminants that render the water unsafe for consumption, use in agriculture, or environmental purposes. It can arise from various sources, such as industrial waste, agricultural runoff, sewage leaks, or natural occurrences like algal blooms. The presence of bad fluid poses significant health risks to humans and animals, damages ecosystems, and can lead to economic losses due to water treatment costs and reduced water availability.
