Turbidity is a key measurement used in water quality management that indicates how clear or cloudy water is. Think of it like checking how clean swimming pool water looks - the clearer the better. Water resource professionals measure turbidity to ensure water is safe for drinking, swimming, or industrial use. It's similar to other water quality measurements like pH levels or chlorine content. When you see this term in resumes, it usually means the candidate has experience with water quality monitoring, testing, or treatment.
