A methodology for space-time classification of groundwater quality

Area of Science:

• Hydrogeology
• Environmental Science
• Water Resource Management

Background:

• Groundwater contamination from human activities poses risks to drinking water supplies.
• Legislation emphasizes groundwater vulnerability and quality standards.
• Effective tools are needed for groundwater quality and quantity assessment in water resource management.

Purpose of the Study:

• To develop and apply an improved groundwater quality classification method.
• To incorporate temporal dynamics into static groundwater quality assessments.
• To assess the groundwater quality evolution in the Modena aquifer plain.

Main Methods:

• Utilized concentration values of hydro-chemical parameters to index natural and man-induced groundwater conditions.
• Developed a "stationary" classification method based on parameter concentrations.
• Enhanced the method by integrating three temporal behavior indexes from 1990-1996 monitoring data.

Main Results:

• The improved method was applied to the Modena aquifer plain.
• Results were presented as space-time classification tables and maps.
• The study provides a dynamic assessment of groundwater quality over time.

Conclusions:

• The enhanced classification method offers a more comprehensive understanding of groundwater quality by including temporal variations.
• This dynamic approach is valuable for territorial planning and effective water resource management.
• The findings highlight the importance of monitoring groundwater quality evolution to address contamination risks.
