Academic Year 2021/2022
Learning outcomes
At the end of the course the student is able to comprehend theory and application implications of: pollution of soil and groundwater by metals, metalloids (natural origin or man made) and organic contaminants (man made origin) like: hydrocarbons, chlorinated solvents, pesticides, emerging contaminants; transport processes of contaminants from a given source toward potential receptors via contamination exposure routes (in air and groundwater). Geologicl, hydrogeologico and geochemical characterization of a contaminated site; sampling and monitoring of contaminated media; remediation of contaminated sites.
Course contents
The course is divided in 2 Modules
Module I – Geochemistry of contaminated sites.
Sampling procedures on water, soil, sediment, air. Sampling strategy. Sample conditioning in relation to the sampled medium. Main instrumentations for geochemical characterization, with particular emphasis on inorganic components. Geochimical maps, threshold values and natural background levels. Migration and partition of inorganic contaminants in the hydrosphere: origin, toxicity and mobility.
Module II – Contaminant hydrogeology and risk assessment.
Physico-chemical properties and mobility of organic contaminants in air, soil and groundwater. Non Aqueous Phase Liquids. Transport of contaminants in the unsaturated zone and in groundwater (advection, diffusion, dispersion, retardation, degradation). Legislation on contaminated sites. Well-head and spring-head protection zones. Characterization, risk assessment and remediation of contaminated sites. Forensic hydrogeology and identification of the polluter.

Module 2 –Contaminant Hydrogeology and Risk Assessment
Lessons (slides) of the teacher uploaded on IOL the day before each lesson.
The teaching material provided by the teacher, along with the notes taken by the student, is to be considered adequate for the preparation of the exam
To integrate:
C.W.Fetter-T.Boving-D.Kreamer "Contaminant Hydrogeology" Waveland Press
Teaching methods
Oral presentations, generally organized as a general overview and case studies as examples. Field trips are planned at sites of interest to complement classroom teaching
For module 2 exercitations in classroom by PC will be performed for risk assessment through freeware codes. Activity on the field concerning hydrogeological monitoring and characterization in a contaminated site
Assessment methods
The exam is based upon a multiple-choice/open answer written test.
The student can refuse the votation only once
The votation is expressed in 30/30 quote.
Teaching tools
Videoprojector, PC, blackboard, demonstration of the use of instruments (in the lab and on the field). PC exercise to perform risk assessment
