Gas testing

Every month we (usually Eleanor and Kristina) spend two days gas testing almost 35 boreholes. Gas testing involves going out on site and testing for e.g. methane, carbon dioxide and oxygen in boreholes on site and also just off site. The gas testing is carried out to monitor the gas levels to confirm that our work on site does not cause any significant changes in the gas levels. The results from the gas testing are then analysed. 
 
We also send off four samples to a laboratory every three months and together these tests give us a good understanding of the gas levels on site.
