UMaT’s Proven Technology to Revive Galamsey-Polluted Rivers in Ghana: Insights from Vice Chancellor Prof. Richard Amankwah

Galamsey, Ghana’s term for illegal small-scale gold mining, has devastated rivers nationwide with heavy metals, sediments, and chemicals. Discover how the University of Mines and Technology (UMaT) positions itself as the key to nationwide river restoration.

Introduction

In a landmark statement at UMaT’s 17th Congregation Ceremony in Tarkwa, Vice Chancellor Prof. Richard Kwasi Amankwah asserted that his institution possesses the commercial capacity, advanced technology, and expertise to restore all rivers polluted by galamsey across Ghana. This claim highlights UMaT’s role in combating illegal mining water pollution cleanup through innovative solutions from its Minerals Engineering Department and Geomatic Engineering experts.

What is Galamsey and Its Impact on Ghana’s Rivers?

Galamsey refers to unregulated artisanal gold mining operations that use mercury, cyanide, and excavators, leading to severe galamsey polluted rivers Ghana. Rivers like the Pra, Ankobra, and Tano suffer from turbidity, heavy metal contamination, and loss of aquatic life, threatening water supply for millions and agriculture.

Analysis

Prof. Amankwah’s remarks, delivered amid the graduation of 2,496 students across various programs, underscore UMaT’s readiness for large-scale UMaT river restoration. The university, a specialist in mining and technology education, has developed a comprehensive system for assessing and purifying contaminated water bodies.

UMaT’s Technological Framework

At the core is satellite imagery analysis led by Prof. Cynthia Boye and her team of Geomatic Engineers. This remote sensing technique captures real-time data on water quality parameters such as turbidity, chlorophyll levels, and sediment loads in rivers near small-scale mining sites. By integrating geographic information systems (GIS), UMaT maps pollution hotspots accurately and efficiently.

Minerals Engineering Contributions

The Minerals Income Investment Department complements this by collecting physical water samples from polluted rivers. Laboratory analysis determines specific purification needs, including pH adjustment, heavy metal removal via adsorption or precipitation, and sediment dredging. This end-to-end approach positions UMaT uniquely for river restoration projects Ghana.

Summary

UMaT Vice Chancellor Prof. Richard Amankwah declared during the university’s 17th Congregation on December 1, 2025, that UMaT holds the technology and know-how to clean every galamsey-polluted river in Ghana. Using satellite-based monitoring and engineering purification methods, the institution urges government collaboration for national deployment.

Key Points

Practical Advice

For stakeholders tackling galamsey polluted rivers Ghana, UMaT’s model offers actionable steps grounded in verifiable technology.

Step-by-Step Implementation Guide

1. Initial Assessment: Deploy satellite imagery to identify polluted rivers. Tools like Landsat or Sentinel satellites provide free, high-resolution data for turbidity mapping.
2. Site Sampling: Collect water, sediment, and biota samples from high-risk areas, analyzing for mercury (above 0.001 mg/L WHO limit), arsenic, and lead.
3. Purification Design: Use engineering solutions like constructed wetlands for natural filtration, coagulation-flocculation for sediments, and bioremediation for organics.
4. Monitoring and Maintenance: Establish GIS dashboards for ongoing satellite surveillance to track restoration progress.
5. Partnerships: Collaborate with institutions like UMaT for scalable deployment, involving local communities in monitoring.

This pedagogical approach educates on sustainable UMaT river restoration practices, ensuring long-term water security.

Points of Caution

While UMaT’s capabilities are promising, successful illegal mining pollution cleanup Ghana requires careful consideration:

• Scale Challenges: Nationwide restoration demands vast resources; pilot projects on rivers like the Pra demonstrate feasibility before full rollout.
• Ongoing Pollution: Galamsey activities must be curtailed concurrently, as restoration alone cannot counter continuous contamination.
• Cost Factors: Commercial viability hinges on funding; satellite tech is cost-effective, but dredging and treatment require investment.
• Environmental Variability: River dynamics like seasonal flows affect monitoring accuracy, necessitating ground-truthing with samples.

Comparison

UMaT’s integrated satellite and engineering approach stands out against other Ghanaian efforts.

Vs. Government Initiatives

The Inter-Ministerial Committee on Illegal Mining (IMC) focuses on enforcement and bans, with limited tech-driven restoration. UMaT adds scientific precision via satellite imagery water quality monitoring Ghana.

Vs. Other Institutions

Kwame Nkrumah University of Science and Technology (KNUST) researches bioremediation, but UMaT’s mining expertise and geomatics leadership provide a holistic edge. International comparisons, like Brazil’s Amazon mercury cleanup using drones, align with UMaT’s remote sensing but lack Ghana-specific adaptations.

Effectiveness Metrics

Legal Implications

Galamsey is illegal under Ghana’s Minerals and Mining Act (2006) and Environmental Protection Agency regulations, prohibiting operations without licenses and mandating environmental impact assessments. UMaT’s involvement could support enforcement by providing evidence from satellite data for prosecutions. Restoration efforts align with the National Water Policy (2007), which requires polluted water body rehabilitation. However, deployment needs government contracts to avoid liability issues in handling hazardous wastes like mercury-laden sediments.

Conclusion

Prof. Richard Amankwah’s proclamation positions UMaT as Ghana’s frontrunner in river restoration Ghana galamsey. By merging satellite imagery, precise sampling, and minerals engineering, UMaT offers a verifiable path to revive vital water resources. Policymakers must heed this call, fostering partnerships to transform polluted rivers into sustainable assets for future generations.
