Description

The purpose of this module is to 1. appreciate the importance and challenges of water analysis. 2. appreciate the weaknesses in analytical approaches 3. To learn the analytical approaches used to study of water. 4. To apply theoretical knowledge in a field setting. 5. To develop record keeping and report writing skills. 6. To develop inter-personal and communication skills.

Learning Outcomes

1. Understand water quality challenges and the analytical tools that are commonly used to monitor the health status of water.
2. Gain an appreciate of the limits of these techniques and the wider sampling and analytical approach sometimes required.
3. Use modern techniques for the assessment of water quality.
4. To experience the demands of working in groups.
5. To be competent in report writing and presentation/interpretation of scientific data.

Reassessment Requirement Type
Resit arrangements are explained by the following categories: Resit category 1: A resit is available for both* components of the module. Resit category 2: No resit is available for a 100% continuous assessment module. Resit category 3: No resit is available for the continuous assessment component where there is a continuous assessment and examination element.
* ‘Both’ is used in the context of the module having a Continuous Assessment/Examination split; where the module is 100% continuous assessment, there will also be a resit of the assessment
This module is category 2
