Restoring Land and Safeguarding Water

Introduction

Spain’s landscape is as varied as its culture fertile farmlands in Andalusia, industrial corridors in Catalonia and the Basque Country, and rapidly growing urban hubs like Madrid and Barcelona. Yet, alongside this growth, decades of intensive agriculture, mining, and industrial activity have left behind a less visible legacy: contaminated soils and groundwater. Pesticide residues in agricultural regions, petroleum leaks near refineries, and heavy metals from mining districts such as Asturias and Andalusia continue to put pressure on ecosystems and local communities.

As demand for clean water increases and European Union environmental directives grow stricter, soil remediation in Spain has become a priority for both public and private sectors.

At The Ground Water Company, we help industries, municipalities, and landowners across Spain restore polluted land, protect aquifers, and create pathways for sustainable development.

What Is Soil Remediation?

Soil remediation is the process of cleaning up and restoring contaminated soil to make it safe for people, plants, and animals. It’s commonly used at sites where industrial activities, chemical spills, or improper waste disposal have polluted the ground.

• Agriculture – Overuse of fertilizers and pesticides, particularly in Andalusia, Murcia, and Castilla-La Mancha.
• Industry & Transport – Hydrocarbon spills and chemical residues around ports, refineries, and industrial hubs.
• Mining – Heavy metal contamination from historic and ongoing operations in Asturias, León, and Andalusia.
• Urbanization – Construction debris and waste disposal associated with rapidly growing metropolitan regions.

Key Soil Challenges in Spain

Spain’s environmental pressures make soil and groundwater management a complex challenge:

• Agricultural Intensity – Irrigation and fertilizer use contribute to nitrate and pesticide build-up.
• Mining Legacy – Old mining districts continue to release metals into surrounding soils and rivers.
• Industrial Footprint – Petroleum and chemical residues impact coastal and inland water resources.
• Water Scarcity – With many regions relying heavily on aquifers, contamination directly affects drinking water and agriculture.
