    Study Notes

    Contaminant Release from Hazardous Waste Sites

    • The three phases of contaminant release from hazardous waste sites are: • Source release: contaminants are released from the waste into the surrounding soil and groundwater • Transport: contaminants are transported through the environment via air, water, or soil • Fate: contaminants are transformed or degraded through chemical or biological reactions

    Air Emissions

    • The types of air emissions mentioned in the text are: • VOCs (Volatile Organic Compounds) • Particulates • Gases

    Contaminant Release Terminology

    • In the context of contaminant release, a 'puff' refers to a sudden release of contaminated air or gas

    Environmental Quality (Scheduled Waste) Regulations 2005

    • The focus of Environmental Quality (Scheduled Waste) Regulations 2005 is on the management of scheduled waste, particularly the reduction of environmental pollution from industrial activities

    Fate and Transport of Contaminants

    • The primary mechanism of fate and transport of contaminants in the environment is through advection, dispersion, and diffusion
