Contaminant Plume related to Site Condition & Contaminant Source

SCOPE of Environmental Geotechnics

Protection of ground water aquifers from contamination (Containment) Assessment of pollutants being discharged on/in the soil deposits (Disposal/Handling/storage) Process by which the pollutants travel in geo-environment (Contaminant Transport) Methods of cleaning the contaminated sites (Remediation)

Precipitation Landfill Stationary W.T. Contaminant plume Leachate Hard rock (Impervious,Aquitard) Soil G.L.

Spread of Contaminant(s)

Containment /Barrier (Sheet pile/grout)

(Waste-Environment Interaction)

Precipitation Landfill Moving W.T. plume Hard rock (Impervious,Aquitard) Monitoring Extent (time & space) Intensity Concentration G.L.

Spread of Contaminant (another scenario)

Soil Calls for: Modeling (to predict transport & fate of contaminants in geoenvironment) Validation
