Soil contamination occurs when the excessive accumulation of substances reaches levels that negatively affect the survival and development of living beings.

Pollutants are first absorbed by vegetation and then are consumed by animals or humans in what is called the food chain. These polluting substances can also pass into groundwater and therefore also be consumed by humans and / or animals.

The main soil pollutants include:
Metales pesados, microorganismos patógenos, hidrocarburos, plaguicidas, basura, ácidos y aguas de relave, entre otros. Cuando un terreno ya está afectado, la solución es la remediación de suelos contaminados, que parte con un análisis de residuos para identificar qué contaminantes están presentes.
