To ask the Scottish Government what analysis it has conducted of any potential water pollution as a result of unconventional gas exploration and extraction and whether it is considering commissioning further research.
Following the investigation of two seismic tremors experienced near Preese Hall, Lancashire during fracking operations in 2011, the Royal Academy of Engineering and the Royal Society conducted a wide ranging and authoritative review of the scientific and technical evidence on the risks associated with hydraulic fracturing for shale gas, and published a report in June 2012. Their overall conclusion is that the risks can be managed effectively in the UK as long as operational best practices are implemented and enforced through current regulation, a position shared by The Scottish Environmental Protection Agency (SEPA).
Whilst we and SEPA believe that the current regulatory tools provide a high level of protection, it should be noted that shale gas activity, including hydraulic fracturing, is only exploratory and there is no experience of production operations in the UK as yet. Therefore we will monitor any future activity to ensure that the current tools are effective in protecting the water environment and if not will look at further measures at that point.
