EQGI: Environmental Quality Grade Index for Integrated Classification and Quantification

An Excel dataset containing the Environmental Quality Grade Index (EQGI), a tool developed to address the lack of a single indicator for water quality management. EQGI creates a linear mapping between quality classification numbers and standard limits, converting monitoring values into dimensionless decimals. The dataset, authored by Lianjie Zhang and last updated in May 2026, is 15.5 KB and available under a CC-BY-4.0 license.

Use Cases

• Classifying environmental quality based on the EQGI's decimal conversion method.
• Quantifying the gap between monitoring values and management goals using the dimensionless index.
• Analyzing water quality status, trends, and spatial distribution with a single integrated metric.
• Supporting public disclosure of environmental quality information using the EQGI's simplified output.

Strengths

• Dataset provides a specific methodological tool (EQGI) for integrated environmental assessment.
• File is small (15.5 KB) and in a widely accessible format (XLSX).
• License is open (CC-BY-4.0), permitting reuse and modification.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The description does not specify the geographic scope or source of the underlying monitoring data.
• The dataset's small size suggests it likely contains methodological calculations or examples rather than extensive monitoring records.
