What Does ZID Stand For?

ZID stands for Zone Of Initial Dilution

ZID, or Zone Of Initial Dilution, refers to the area surrounding a discharge point in an aquatic environment where pollutants are initially mixed and diluted with the receiving water body. This zone is critical for assessing the environmental impact of effluent discharges, as it helps determine the dispersion patterns and concentration levels of contaminants before they spread further into the surrounding ecosystem. Understanding the ZID is essential for effective water quality management and regulatory compliance.
