To address the impact of acid mine drainage (AMD) on groundwater quality in the Picentini Mountains, specifically within the Cilento and Vallo di Diano National Park, a comprehensive approach is necessary. Here's a structured plan based on the thought process:

1. Assessment and Monitoring

  • Data Collection: Gather existing data on groundwater quality from local authorities or conduct new sampling to test for pH, heavy metals, and sulfates.
  • Source Identification: Use GIS mapping and historical records to locate old mines and tailings. Prioritize sources based on contamination levels.

2. Monitoring Network

  • Setup: Install a network of monitoring points around mining areas, including upstream and downstream locations.
  • Automated Sensors: Deploy sensors for real-time data on pH, temperature, and conductivity to detect water quality changes.

3. Hydrological Modeling

  • Groundwater Flow Models: Utilize models like MODFLOW to predict contamination spread and assess risks to ecosystems and human health.

4. Mitigation Strategies

  • Passive Treatment: Consider wetlands or anoxic limestone drains, verifying effectiveness in local geology.
  • Active Treatment: Implement chemical neutralization with lime, acknowledging the need for ongoing maintenance.
  • In Situ Remediation: Explore injection of neutralizing agents, consulting experts on feasibility.
  • Mine Rehabilitation: Cover tailings and revegetate to reduce AMD generation, ensuring environmental preservation.

5. Community Engagement and Collaboration

  • Education and Involvement: Engage locals in monitoring and awareness programs, leveraging their insights.
  • Collaboration: Work with national park authorities, local government, and academic institutions for resources and expertise.
  • Funding: Seek grants from environmental programs to support initiatives.

6. Regulatory Compliance and Sustainability

  • Legal Framework: Ensure compliance with Italian environmental laws and integrate measures into park management plans.
  • Cost-Effective Solutions: Explore alternatives and combine approaches to manage costs and ensure long-term sustainability.

7. Adaptive Management

  • Regular Reporting: Maintain transparency through reports and adjust strategies based on new data and effectiveness.

By integrating these steps, the plan aims to effectively monitor and mitigate AMD impacts, ensuring sustainable protection of groundwater quality in the region.
