Environmental Management and Pollution Control
What to understand
Know the main environmental receptors - air, water, land, biodiversity, people - and the pollution pathways that link a source to a receptor. Understand the source–pathway–receptor model as a tool for both assessment and control. Learn the principles of environmental management: prevention, minimisation, reuse, recycling, recovery, disposal (waste hierarchy), and the polluter pays and precautionary principles. Know the main categories of pollution (air emissions, effluent, noise, waste, spills) and controls such as bunding, containment, treatment, monitoring and permits. Understand environmental impact assessment and the role of regulatory permits and reporting.
Traps
- Treating dilution as a control; it only shifts the problem.
- Forgetting that spills can reach water via drains; know where drains lead.
- Confusing waste disposal with waste minimisation.
- Overlooking noise and light as pollution.
- Ignoring legal reporting duties for environmental incidents.
Worked example / rule of thumb
A drum of oil leaks on site. Source: drum. Pathway: surface, drains, soil. Receptor: watercourse, groundwater. Control: bund the drum, seal drains, absorb and contain the spill, dispose of waste correctly, notify as required. Rule of thumb: break the pathway - contain, intercept, or remove the receptor - and always know where your drains go.
Practical skills
Apply the waste hierarchy, describe bunding and secondary containment, and explain monitoring and reporting obligations.
