Which of the following is an indicator of potential water contamination?

High turbidity levels serve as a key indicator of potential water contamination due to their relationship with suspended particles in the water. Turbidity measures the cloudiness or haziness of a water sample, often caused by the presence of microorganisms, sediments, or pollutants. Elevated turbidity can signal that harmful contaminants, such as bacteria, viruses, or chemical residues, may be present, as these particles can harbor pathogens that pose health risks when consumed or contacted. Monitoring turbidity is crucial in assessing water quality and ensuring that it meets safety standards for human consumption and ecological balance.

Low pH levels could indicate acidification but may not necessarily correlate to contamination. Increased water pressure typically relates to system performance rather than contamination. Stable temperature readings are important for understanding water system dynamics, but on their own, they do not indicate contamination risk. Thus, high turbidity levels are a clear warning signal that further investigation into water quality is needed.
