Pollution transfer in soil and water environment 1300-OMZGW-GES
The lecture is concentrated on:
Basic processes conditioning the pollution transfer in groundwater:
• hydrogeological conditions of pollution transfer
• anthropogenic and geogenic contamination
• the scale problem in interpretation of the phenomena of mass transport in groundwater flow
• determination of migration time in unsaturated and saturated zone (advection, diffusion)
• tritium as a tracer of pollution transfer
• medium rock impact on migration of pollution in an aquifer (determination of the average effective velocity of water in an aquifer, the dispersion parameters, flow parameters, diffusion, sorption and decay parameters or biodegradation of migrant)
• flow scheme of the exchange processes between the aqueous solution and a rock
• retardation of substances transfer in groundwater flow (retardation coefficient)
• sorption processes - as a factor in delaying the migration of pollution in groundwater flow (isoelectric point, the ranks of ion exchange, sorption isotherms, evaluation of saturation of the sorption complex by pollutant)
• role of carbonates, organic matter and micro-porosity rock matrix in migration of pollutants in an aquifer
Examples of threats of groundwater - the method of prevention:
• propagation of petroleum pollution in soil and aquatic environment and a n overview of the methods of remediation of soil and groundwater from pollutants with oil substances
• pollution of groundwater by pesticides and the methods of their prevention
• factors determining of pesticide biodegradation
Cartography in the service of groundwater protection:
• degree of potential thread of an useful aquifer
• The Map of Vulnerability of Groundwater in 1 : 500 000
• The Hydrogeological Map of Poland in 1 : 500 000 – first aquifer, vulnerability of pollution and quality.
