Monitoring points consist of a variety of sites throughout the UK at which environmental data are gathered by the Authority. The types of data collected include water level, mine gas concentration, flow rate, chemistry and pumping data. Within the last thirty years or so as coal production in the UK has reduced so have the underground pumping arrangements. This cessation has allowed underground water levels to rise and outbreaks to occur at the surface. The Authority currently operates a number of mine water treatment schemes in order to remediate existing discharges and prevent new discharges from coal mine workings.
