Introduction to Environmental Engineering
Environmental engineering applies science and engineering principles to protect human health and the natural environment.
Core Areas
Water & Wastewater Treatment
- Removal of contaminants from drinking water and sewage
- Processes: coagulation, sedimentation, filtration, disinfection
Air Quality
- Control of particulate matter, NOₓ, SOₓ, VOCs
- Monitoring and modeling air pollution
Solid & Hazardous Waste
- Landfill design, remediation, recycling systems
Environmental Impact Assessment (EIA)
- Evaluating project effects before construction
Key Parameters in Water Quality
| Parameter | Significance | |-----------|-------------| | BOD (Biochemical Oxygen Demand) | Organic pollution indicator | | DO (Dissolved Oxygen) | Aquatic life survival | | pH | Acidity/alkalinity | | Turbidity | Suspended solids | | Coliform Bacteria | Fecal contamination |
The Water Cycle in Engineering Context
- Precipitation → runoff and infiltration
- Collection → reservoirs and groundwater wells
- Treatment → water treatment plants
- Distribution → pipes to homes/industry
- Collection → sewers and wastewater plants
- Discharge → treated effluent to waterways
Relevant Regulations (US)
- Safe Drinking Water Act (SDWA)
- Clean Water Act (CWA)
- Clean Air Act (CAA)
- RCRA (solid/hazardous waste)
- CERCLA / Superfund
Summary
Environmental engineering bridges public health, ecology, and infrastructure. It is increasingly critical as population growth and climate change put pressure on natural resources.
