Heavy metals, organic pollutants, and hazardous substances are accumulating in soil due to human activities in industry, agriculture, and urbanization. As economies grow, strategies are needed to reduce chemical inputs, remediate contaminated lands, and raise awareness about responsible land management practices. Bioremediation, which employs microorganisms to degrade soil contaminants, shows promise as a remediation approach. These microbes can break down complex organic pollutants and transform metal contaminants. Bioremediation can be performed in situ or ex situ depending on site constraints and contaminant characteristics. Challenges include slow progress under ambient conditions and the need for nutrients, water, and oxygen input. In addition, constant monitoring is crucial for efficacy and safety. Whereas, bioremediation offers a sustainable and energy-efficient alternative when combined with physical and chemical methods. Cutting-edge microbiology technologies emphasize efficiency through tailored microbes and optimized biostimulation strategies. This chapter addresses soil contamination and the environmental advantages of microbial remediation.
