Leachate from landfills containing hazardous substances (code 19 07 02*) forms when rainwater filters through layers of waste, collecting a mix of contaminants. These include heavy metals, toxic compounds, and microbial threats.
Hazardous waste management of landfill leachate requires constant monitoring, safe collection, and secure transport to avoid environmental damage.
Leachate typically contains:
- ammonium, nitrates, phosphates
- heavy metals like lead, mercury, cadmium
- organic pollutants such as phenols, oil derivatives
- bacteria and pathogens
Hazardous waste handling involves sealed drainage systems and lined collection basins.
Hazardous waste storage requires periodic pumping, leak prevention, and maintenance of containment units.
Hazardous waste transportation of leachate uses tankers with sealed systems and full documentation.
Hazardous waste recycling includes physical, chemical, biological, and membrane filtration methods.
Environmental servicing for landfills must include automated monitoring systems, infiltration barriers, and ecological inspections.
Risks of poor leachate handling include:
- toxic seepage into groundwater
- mass die-offs of local wildlife and plants
- health threats to nearby populations
- secondary contamination during transport
Proper treatment and monitoring of leachate are vital for long-term environmental safety.
