Main Sources of Water Pollution
Spills to drains or ground, industrial drainage and effluent, agricultural runoff, process and cooling water, sewage, solids and natural contaminants.
How to prepare for EMC1 and EMC2
Learn the principle, find organisational evidence, trace aspect to impact, evaluate significance and controls, and recommend proportionate action.
Core concepts
Concept 1
Spills to drains or ground, industrial drainage and effluent, agricultural runoff, process and cooling water, sewage, solids and natural contaminants.
Exam cue: Identify the activity, environmental interaction, operating condition, pathway and receptor before selecting a control.
Concept 2
Trace the source through surface drainage, soil, groundwater, sewer or direct discharge to the receptor.
Exam cue: Prefer prevention and source reduction, then verify controls with suitable monitoring, records and review.
Concept 3
A release onto land may still reach controlled water through infiltration or runoff.
Risk pitfalls and guardrails
Giving a generic environmental measure without connecting it to the organisation, impact and applicable requirement.
Guardrail: Do not give a generic environmental measure without identifying the activity, pathway, receptor and method of verification.
Treating a policy, permit, contractor or item of equipment as proof that environmental performance is controlled.
Guardrail: Do not give a generic environmental measure without identifying the activity, pathway, receptor and method of verification.
