Machine Learning for Sustainable Groundwater Management Under Fluoride Contamination in Balochistan
Fluoride contamination poses significant health risks and challenges sustainable drinking water supply, especially in arid regions like Balochistan. This study introduces an AI-driven spatial modeling framework, using a Support Vector Classifier (SVC), to accurately predict and map fluoride contamination hotspots in groundwater. By integrating hydrogeochemical analysis with machine learning, it offers a robust tool for identifying high-risk areas, ensuring evidence-based intervention strategies, and promoting the Sustainable Development Goal of Clean Water and Sanitation (SDG#6).

ML-Based Spatial Risk Mapping: Precision in Prediction
This study pioneers a machine learning-driven spatial modeling framework to classify groundwater fluoride contamination. It leverages physicochemical parameters and an integrated feature importance framework (hydrogeochemical analysis, spatial distribution, and SHAP) to develop high-resolution susceptibility maps, outperforming traditional geostatistical methods in capturing nonlinear relationships.
Enterprise Application:
For water utility companies and environmental agencies, this translates into a powerful predictive tool. It enables precise identification of high-risk contamination zones, optimizing resource allocation for monitoring, treatment, and intervention. The integration of SHAP provides explainability, crucial for regulatory compliance and stakeholder trust.
Hydrogeochemical Controls: Understanding the Source
The analysis confirms that rock-water interactions, particularly fluorite dissolution and carbonate weathering, are the primary drivers of fluoride enrichment. Parameters like turbidity, SO₄²⁻, pH, HCO₃⁻, Na⁺, Ca²⁺, EC, TDS, and Cl⁻ were identified as key predictors, consistently showing importance in SHAP analysis and physical relevance to fluoride mobilization.
Enterprise Application:
This deep understanding of geochemical controls empowers water resource managers to design targeted mitigation strategies. For instance, knowing that alkaline conditions favor fluoride mobilization can inform decisions on aquifer recharge management or the selection of treatment technologies. This reduces costly trial-and-error approaches and enhances operational efficiency.
Human Health Impact: Prioritizing Vulnerable Populations
A comprehensive human health risk assessment was conducted using Chronic Daily Intake (CDI) and Hazard Quotient (HQ) indices. Findings indicate children are significantly more vulnerable (51.1% of samples had HQ child > 1) than adults (5.68% had HQ adult > 1). Five specific water supply schemes serving 9,700 people were identified as high-priority for intervention, with both child and adult HQ exceeding 1.
Enterprise Application:
For public health organizations and municipal water authorities, this provides actionable intelligence to prioritize interventions. By pinpointing specific high-risk communities and understanding differential vulnerability (children vs. adults), resources can be allocated effectively for health campaigns, alternative water provisions, or targeted treatment plant installations, leading to improved public health outcomes and reduced long-term healthcare costs.

SHAP Analysis: Influential Hydrogeochemical Parameters
The SHAP summary plot (Figure 12) revealed that Turbidity and SO₄²⁻ were the most significant features contributing to high fluoride concentrations, followed by pH and HCO₃⁻. Elevated values of these parameters predominantly drove positive SHAP values, aligning with the understanding that alkaline conditions promote fluoride mobilization. Conversely, Ca²⁺ exhibited mixed contributions, often associated with reduced fluoride probability, potentially reflecting fluorite precipitation effects. This detailed insight into feature importance allows the SVC model to capture the complex rock-water interactions that control fluoride distribution effectively.
