The International Association of Oil and Gas Producers (OGP) have published information relating to the chemicals used during the fracking process to liberate shale gas. Shale gas is seen by many as an important component of the energy mix in many Western countries, including the UK in the short to medium term, but environmentalists have voiced concerns over the chemicals used in the fracking process which could potentially find their way into public water supplies.
The information published by OGP currently relates to wells in Poland, where shale gas extraction has commenced, but gives a good indication of the types of chemicals which could be used in the UK. For example, the factsheet for the well at Strzeszewo lists the composition of the fracking liquid used in the process. Many of these are very common chemicals at very low concentrations and of limited harm, but they do present a potential challenge to analytical chemists to monitor for their presence in drinking water supplies which could potentially be affected by fracking in the vicinity of wells.
