The course focusses on geochemistry of natural water as imprinted by its interaction with local geology.  It takes an integrated view of natural and biological (anthropogenic) interactions that shape the earth¿s surface.Significantly, the approach is based on integrating theoretical geochemistry with practical skills such as (i) data processing and statistical analysis, (ii) geochemical modelling, (iii) environmental remediation.

| Feedback | 
The course includes laboratory practical sessions for which you will submit written reports. The first of these will be used for formative feedback to allow you to improve on subsequent reports. You will also get on-going feedback from demonstrators during and after practical sessions.  
As this is a new course, we plan to hold 1-2 tutorials during exam revision session. During these sessions, we will review the type of questions likely to come up in the exam and discuss how best to tackle them. 
In semester 2, the course team will be available to discuss examination scripts.
