The keywords that describe this course are: “Water properties. Equilibrium in aquatic systems. Air-water and soil-water interactions. Criteria and regulations. Contamination of natural waters. Quality indexes. Analytical techniques for characterization”.
Considering these keywords and the organization of the course, comprising theoretical and laboratory sessions, the syllabus will be divided into two blocks:
- One block consisting of theoretical units in which general concepts are explained to define the chemical behavior of natural aquatic systems and water quality along with the required methodology to determine it.
- One block focused in practical learning where the above explained methodology will be applied to the study of the water quality of a real system.
The course will be basically practical with special attention to the typical problems that the Chemical Engineer will face in the future regarding the quality of surface aquatic systems. The laboratory practicals will be useful to complete the knowledge acquired in the theoretical classes.
During the course the student will acquire and practice a series of general and specific competences which are desirable in any University degree and particularly for environmental professionals.
The students should become aware of the problems that pollution can cause in the environment and be able to design a protocol to determine water quality and assess a whole set of physical, chemical and biological parameters that help us to establish the different quality indexes and water quality indexes.
The contents of the course will be basically those mentioned in the keywords.
The different units of the course will comprise a theoretical and a practical part.

Basic and general
CB6 – To possess and understand the knowledge that provides a basis and opportunity to be original in the development and/or application of ideas, often in a research context.
CB7 - Students should be able to apply their knowledge and their ability to solve problems in new or unfamiliar environments within broader (or multidisciplinary) contexts related to their field of study.
CB8 - Students should be able to integrate knowledge and handle complexity to formulate judgments based on information that was incomplete or limited, and that include a thought on social and ethical responsibilities linked to the application of their knowledge and judgments.
CB9 - Students should be able to communicate their conclusions, the knowledge and rationale underpinning these to specialist and non-specialist audiences clearly and unambiguously.
CB10 - Students must possess the learning skills that enable them to continue studying in a way that will be largely self-directed or autonomous.
G01 - Identify and articulate environmental problems
Specific
E11 - To have a comprehensive understanding of environmental problems .
E13 - To know the scientific bases that are applied by the environmental engineering.
E16 - Meeting environmental legislation at local, regional and global levels.
E21 - Identify and formulate environmental problems.
E31 - Conduct literature review and synthesize results.
E34 - Write reports on impacts and environmental issues .
E42 - Commitment to environmental protection and sustainable development.
Empleo del Campus Virtual. A través de la plataforma Moodle se empleará el Aula Virtual de la USC. En ella se subirán, además de toda la información referente al curso (profesorado, horarios y programación), diversos materiales de apoyo al estudio y al trabajo personal, tales como artículos científicos, legislación en temas de calidad de aguas, presentaciones PowerPoint de las clases, videotutoriales sobre manejo de programas de especiación, vídeos de interés para la materia, documentos de consulta, actividades para el trabajo personal, etc.
Habrá clases expositivas en las que se sientan las bases para desarrollar el concepto de calidad del agua y se definirán distintos índices e indicadores de calidad. En las clases interactivas se aplicarán los conceptos y competencias adquiridas a la resolución de ejercicios mediante software específico para cálculos de especiación en medios naturales.
La materia incluye también la realización de muestreos y medidas in situ durante una salida de campo al río Sar (en las proximidades de Santiago de Compostela) y una jornada de visita a la Estación de Hidrobiología Encoro do Con. Los desplazamientos para la realización de ambas actividades serán en autobús en los días marcados en el calendario.
Las clases prácticas de laboratorio se desarrollarán en los laboratorios de la ETSE y los alumnos estarán divididos en dos grupos de aproximadamente 12 personas.
La admisión y permanencia del alumnado matriculado en el laboratorio de prácticas requiere que conozcan la información y cumplan las normas incluidas en el Protocolo de formación básica en materia de seguridad para espacios experimentales de la Escuela Técnica Superior de Ingeniería, disponible en el apartado de Seguridad de su web.
Para os casos de realización fraudulenta de exercicios ou probas será de aplicación o recolleito na Normativa de avaliación do rendemento académico dos estudantes e de revisión de calcificacións.
A asistencia ás clases de Laboratorio é obrigatoria, sen esa asistencia o alumno non pode ser avaliado en ningunha convocatoria.
Ao longo do curso realizaranse diferentes actividades. Algunhas serán entregadas aos profesores e outras serán presentadas na aula para ser defendidas e discutidas co resto dos compañeiros e o profesorado. Non haberá un exame final típico. Con todo, na data programada para tal fin, todos os alumnos deberán presentar un informe final da materia que previamente entregarán a través do Campus Virtual. O devandito informe debe incluír unha visión integradora dos contidos traballados na materia, enfocando todos eses contidos cara a avaliación da calidade da auga do río/ríos cos que se traballou nas prácticas de laboratorio. Debe incluír, por tanto, desde o deseño da mostraxe, pasando polas técnicas analíticas empregadas para a determinación da calidade da auga no laboratorio, ata a elaboración dos índices de calidade correspondentes e a súa análise desde o punto de vista da normativa vixente.
A avaliación farase en base ás competencias adquiridas, de forma que estas serán avaliadas nas diferentes actividades realizadas ao longo do curso.
Actividades:
1. Deseño dun plan de mostraxe
2. Saída ao campo para a toma de mostras de auga (ríos Sar e Sarela)
3. Prácticas de Laboratorio
4. Casos prácticos
5. Informe final

• Presentación oral (baseada na actividade 5)
70% Avaliación continua
• Actividade 1: 15%
• Actividade 3: 20%
• Actividade 4: 35%
En caso de ter que presentarse á segunda oportunidade de exame, gardaranse as calcificacións de aquelas actividades que estean aprobadas (nota por encima de 5). Só se entregará de novo a parte que non fose superada na primeira oportunidade de exame (nota inferior a 5).
Os estudantes repetidores terán que volver realizar todas as actividades xa que estas adoitan cambiar dun ano para outro. Realizaranse de novo as prácticas de laboratorio xa que toda a materia (actividades, traballos e exame) céntranse nelas.
