Another Derbyshire Tar Pit.

June 27th, 2020 in featured by Noreen Shears

A pressing issue for the Trust is this tar pit that is a threat to one of the tributaries of the River Derwent in Derbyshire.

This site is close to the trial we have been working on for two years and had originally been incorporated into the initial scheme but due to the draught of 2018 had to be abandoned for the main project.

As the photographs demonstrate the tars are more liquid than those on the other site which were soft, these emerge from the ground as a viscous liquid and are not so acidic (pH4.5 to 5.5). The bacteria tar mix which is the obvious in its staining is neutral with a pH 6.5 to 7.

The emulsions apparent on the surface are the bacteria breaking down the tars which are then available as an energy source for other bacterial actions. The bacteria are a natural occurrence that have developed on site over the time since the tar was deposited on site by the polluter in the 1970s.
