INSTRUCTIONS Answer the following question. Word Limit: 2000 words excluding tables and diagrams Scenario Among hydrocarbon pollutants, diesel oil is a complex mixture of alkanes and aromatic compounds that frequently are reported as soil contaminants leaking from storage tanks and pipelines. One of the best approaches to restoring contaminated soil is to make use of micro organisms able to degrade those toxic compounds in a bioremediation process. An old disused airfield (approx 15000 m2) has been identified as having hydrocarbon contamination; however the extent of the contamination has not yet been confirmed. The hotspot has been identified as a circular area of approx. 50m2. (Assumption is that the contamination is limited to soil only). It has been suggested that the site may be used for the development of residential properties. Task 1 Suggest a suitable sampling regime for this area. Your regime should identify No of sampling points Sampling depth Sampling pattern. (30%) Task 2 Having undertaken initial trials using in situ biostimulation and bioaugmentation you have obtained the results as observed in Table 1. Produce a report presenting these results to the developer explaining (graphically and statistically) which method worked best. (30%) Task 3 In addition to reporting the results you have also been asked to produce a scientific review of both techniques outlining previous research (both field and lab based), highlights and limitations. (40%) Table 1: Results for laboratory trials.
