Objectives

This curricular unit presents fundamental and applied aspects on the characterization of effluents, contaminated soils, and solid wastes. Benefiting from knowledge and skills previously acquired, it also provides a comprehensive and coherent set of concepts, along with tools for the characterization and analysis of effluents, contaminated soils, and solid waste. The unit also promotes a critical understanding of the advantages and limitations of the different analytical methodologies, as well as their adaptation to different case studies.

Learning outcomes and competences

This curricular unit expects students to acquire:

-Knowledge of the legislation regarding water quality and waste, air quality and atmospheric emissions, waste characterization and classification, and wastewater discharge standards.

-Be acquainted with the methodologies for sampling water and groundwater, atmospheric pollutants and gaseous emissions, soil and waste, the main parameters of characterization and analytical methods.

-Team work training, in terms of development, and problem solving.

Program

1. Importance of the composition of wastewater, solid waste and sludge. Physical composition. Chemical composition. Most common parameters in the evaluation of the physical, chemical and microbiological composition. Importance of detection and characterization of contaminated sites.


2. Methodologies for the characterization of wastewater, soils and solid residues.


3. Sampling, characterization of waste and their evaluation for adequate management.


4. Leaching tests and admissibility criteria for landfill deposition according to the Portuguese regulation D.L nº 183/2009.


5. Water quality standards and industrial and urban wastewater discharge limits.


6. Sampling and assessment of the need for a corrective action plan for contaminated areas. APA reference guides, based on Dutch and Ontario legislation, for assessing contaminated soil.


7. Gaseous effluents: definition, main atmospheric pollutants pollutants, their characteristics, emission sources; sampling; legislation.

Eligibility for exams

According to General Evaluation Rules of FEUP.

Calculation formula of final grade

The final grade will be based on the average grade of all four modules: Water and Wastewater, Gaseous Effluents, Soils and Solid Waste:

FG = 0,35WWC + 0,30SWC + 0,20GC + 0,15SC

With WWC - grade for water and wastewater characterization; SWC - grade for solid waste characterization; GC - grade for gaseous effluents characterization; SC - grade for soils characterization.

The evaluation will be carried out in 2 written tests and 2 group projects, with the first written test (WT1) focusing on the Water and Wastewater (WW) and the Gaseous Effluents (G) modules, and the second written test (WT2) focusing on the Soils (S) and Solid Waste (SW) modules. The group projects will focus on the Water and Wastewater (GP1) and the Solid Waste (GP2) modules, respectively.

For the modules with a group project the grade weighting will be 60%/40% between the written test and the group project, respectively.

Therefore and taking into consideration the abovementioned grade weightings, the final grade of the 1st grading season will result from the application of the following detailed formula:

FG = 0,14 GP1 + 0,41 WT1 + 0,12 GP2 + 0,33 WT2

The average grade of the different evaluation components will only be calculated if the student has a minimum grade of 7 in each component. For approval, the final grade must be equal or above 10.

The students that do not reach approval in the 1st grading season will be evaluated in the 2nd exam season where the formula for the final grade will be given by: 

FG = 0,35WWC + 0,30SWC + 0,20GC + 0,15SC

Examinations or Special Assignments

In both modules students will have to carry out a group assignment, in order to apply their knowledge.

Special assessment (TE, DA, ...)

A final exam at the corresponding season.
