Microorganisms have been detected in TRU wastes, Pu-contaminated soils, low-level radioactive wastes, backfill materials, natural analog sites, and waste-repository sites slated for high-level wastes. Seventy percent of the TRU waste consists of cellulose and other biodegradable organic compounds. Biodegradation of cellulose under the hypersaline conditions such as in the WIPP repository can produce CO2 and methane gas, as well as affect the solubility of actinides. Microbially produced gases could have significant ramifications for the long-term stability of the repository.

When you get off the train at Drigg you can’t miss the waste dump. The fence runs right along by the platform and then on for another 1.7 km alongside the railway line. At intervals there are signs on the fence that say it is a nuclear licenced facility. The fence is green as I remember and has that spiralling wire rolled along the top. There is another fence inside this fence and a roadway in between them that a patrolling vehicle drives around. There are some scrabbling holes where rabbits have tried to dig their way in but have not succeeded as the fence goes down into the ground. What we seem to have is a ‘Low Level Waste Repository’ which is very literally at a low level – barely above sea level. It is set in the shifting sands of heathland 300meters from current high tide mark. The dunes/heath are eroding. A watercourse from the site flows into the tidal river Irt just south of the site.
