Environmental Engineering is a specialized branch of engineering that focuses on the application of scientific and engineering principles to address environmental challenges and protect the natural environment. It involves the design, development, implementation, and management of technologies and systems to safeguard human health, promote sustainability, and minimize the adverse impacts of human activities on the environment.

Key aspects:

• Water and Wastewater Management: Treatment and distribution of clean drinking water, as well as the collection and treatment of wastewater and stormwater. Also, to design and operate water and wastewater treatment plants to ensure safe disposal or recycling of these vital resources.
• Air Pollution Control: Studying, monitoring, and mitigating air pollution caused by industrial processes, transportation, and other sources. To develop and implement technologies to reduce emissions of harmful pollutants and improve air quality.
• Climate Change Mitigation and Adaptation: It plays a role in developing strategies to mitigate the effects of climate change, such as designing infrastructure that can withstand extreme weather events and implementing renewable energy projects to reduce greenhouse gas emissions.
• Environmental Policy and Regulation: Working with policymakers and regulatory agencies to develop and enforce environmental laws and regulations that protect the environment and promote sustainable practices.

Environmental engineering research aims to address environmental challenges such as air and water pollution, waste management, and remediation of contaminated sites. The major research areas on which the department works includes the following:

• Atmospheric aerosols, 
• Air quality,
• Climate forcing,
• Source apportionment, 
• Population exposure and health effects,
• Biogeochemical cycling of elements of human health concern and emerging contaminants in the environment,
• Applications of biogeochemical processes in advanced water-wastewater purification, desalination and sustainable water reuse,
• Investigating terrestrial planetary analog sites of astrobiological significance using principles of biogeochemistry.
