SummaryThe course focuses on geochemistry of natural waters as imprinted by its interaction with local geology, biology and during mixing with sea water. It takes an integrated view of the chemical environments of natural waters and the processes that govern them.

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.
Entry Requirements (not applicable to Visiting Students)
Pre-requisites It is RECOMMENDED that students have passed Earth Dynamics (EASC08001) AND Evolution of the Living Earth (EASC08023)
Co-requisites
Prohibited Combinations Other requirements Higher Chemistry
Additional Costs 44 for fieldtrip to the Lake District. Please note, the School subsidy of providing 50% of the cost applies to core courses only, students taking field courses as an elective pay the full cost.

Learning and Teaching activities (Further Info) Total Hours: 200 ( Lecture Hours 20, Supervised Practical/Workshop/Studio Hours 18, Fieldwork Hours 16, Feedback/Feedforward Hours 2, Formative Assessment Hours 2, Summative Assessment Hours 2, Programme Level Learning and Teaching Hours 4, Directed Learning and Independent Learning Hours 136 )
Assessment (Further Info) Written Exam 50 %, Coursework 50 %, Practical Exam 0 %
Additional Information (Assessment) Written Exam: 50%, Course Work: 50 % (35% for lab reports and 15% for fieldtrip report), Practical Exam: 0%.
There will be an exam in December consisting of a mixture of short answer questions and essay questions. The course work will be based on written reports on each of the practicals carried out during laboratory sessions, plus a 2500 word report synthesising and interpreting data collected during the Keswick weekend fieldtrip.

Assessment deadlines
Both Laboratory and Fieldwork reports should be submitted as a single document by Friday of week 9.

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.
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.
