According to new data, the construction industry accounts for 37% of the world’s total carbon emissions.
However, carbon emissions don’t just cease once the equipment is turned off. Between powering these buildings and their impact on local environments, the environmental damage from one project can extend long into the future.
That’s where the environmental engineer’s role comes in: bridging the gap between human development and the sustainable use of natural resources.
These professionals tackle some of the most pressing challenges of our time, ensuring that our planet remains habitable and thriving for future generations. Their work is also important in complying with proper regulations and fostering public trust for projects.
Below, we explore three key areas that environmental engineers significantly impact: water management, sanitation, and air pollution control.
What Is an Environmental Engineer?
An environmental engineer is tasked with solving environmental challenges in construction, urban planning, agriculture, and all layers of human activity.
Their primary focus is to design and implement solutions that protect the environment while promoting human health and well-being.
Environmental engineers work on a wide range of projects, including:
- Designing water and wastewater treatment facilities.
- Developing systems to reduce air and soil pollution.
- Managing hazardous waste and promoting sustainable waste disposal.
- Implementing renewable energy technologies.
- Addressing the impacts of climate change through mitigation and adaptation strategies.
These engineers often collaborate with government agencies, businesses, and community stakeholders to ensure compliance with environmental regulations and to develop innovative, sustainable practices.
To learn more about environmental engineering, let’s look at the three main disciplines of the role.
Protecting Water Quality
Water is the foundation of life on Earth. It is indispensable for drinking, agriculture, industry, and sustaining ecosystems. Environmental engineers are crucial in addressing these challenges through innovative solutions and technologies.
1. Ensuring Clean Drinking Water
One discipline of environmental engineers is designing and managing water treatment systems that remove harmful contaminants such as bacteria, heavy metals, and chemicals.
These tasks require advanced filtration and disinfection methods to make water safe for consumption and protect communities from waterborne diseases like cholera and dysentery.
2. Protecting Natural Water Sources
Pollution from industrial waste, agricultural runoff, and urbanization can be extremely hazardous to nearby rivers, lakes, and groundwater ecosystems.
Environmental engineers work to prevent these pollutants from entering water systems by designing containment strategies, monitoring water quality, and implementing regulations to mitigate contamination.
3. Supporting Agriculture and Ecosystems
Water scarcity can have devastating effects on agriculture and ecosystems. Environmental engineers address these concerns via irrigation systems, rainwater harvesting techniques, and watershed management plans that ensure water resources are utilized sustainably.
Managing Sanitation
Waste must be managed effectively to help prevent disease. Environmental engineers must determine how to reduce waste, properly handle waste at treatment and gray water processing facilities, and keep waste away from clean water sources.
1. Waste Reduction and Recycling
Environmental engineers develop strategies to minimize waste and promote recycling. On worksites, they are often tasked with creating waste management strategies that help prevent worksite hazards, ensure regulatory compliance, and protect stormwater runoff from exposure.
2. Wastewater Treatment
Properly treating wastewater is essential to prevent contamination of clean water sources. Environmental engineers design and operate wastewater treatment facilities that remove pollutants, enabling the safe reuse of water for agriculture, industrial processes, or even potable use.
Reducing Air Pollution
Environmental engineers play a key role in managing pollution and reducing the dangerous chemicals and gases produced by industrialization and manufacturing. They also focus on limiting greenhouse gases and reducing further damage from climate change.
1. Monitoring and Regulating Emissions
Environmental engineers design systems to measure and control factory, vehicle, and power plant emissions. They work with regulatory agencies to establish and enforce air quality standards, ensuring compliance and reducing harmful pollutants like sulfur dioxide, nitrogen oxides, and particulate matter.
2. Limiting Greenhouse Gases
Greenhouse gases, such as carbon dioxide and methane, contribute to global warming. Environmental engineers develop strategies to reduce these emissions, including carbon capture technologies, renewable energy systems, and energy-efficient designs for buildings and transportation.
3. Innovating Clean Technologies
Environmental engineers are often at the forefront of the clean energy movements, helping to incorporate solar and wind technology into net-zero and energy-efficient homes.
Beyond the Basics: Broader Contributions of Environmental Engineering
While water, sanitation, and air quality are fundamental areas of focus, environmental engineers contribute to many other critical issues of human activity, including:
1. Soil Remediation
Soil erosion is a common byproduct of construction-related and agricultural activity that can damage local ecosystems and expose the underlying sediment to stormwater runoff.
Worse yet, contaminated soil from chemicals, such as fertilizers and building equipment, can pose severe risks to agriculture, human health, and ecosystems.
Environmental engineers are often tasked with developing methods to remove or neutralize pollutants in the soil, prevent erosion, restore soil health, and promote usability.
2. Renewable Energy Development
As previously mentioned, environmental engineers are key players in the transition to renewable energy, especially in urban planning and construction.
Environmental engineers can help ensure that buildings are as efficient as possible and use an appropriate amount of renewable energy to achieve net-zero emissions.
3. Urban Planning and Green Infrastructure
Finally, environmental engineers often collaborate with urban planners to design sustainable cities via green spaces, stormwater management, and energy-efficiency technology.
