[问答题]Research published in May 1998 by the Department of the Environment, Transport and the Regions (DETR) showed that reducing coastal and river pollution and ensuring a reliable water supply were among the top environmental priorities for the public.　　All discharges to water in the UK require the consent of the appropriate regulatory authority. In England and Wales the Environment Agency’s principal method of controlling water pollution is through the regulation of all effluent discharges, including sewage, into groundwater, and inland and coastal waters. The Agency maintains public registers containing information about water quality, discharge consents, authorizations and monitoring. Applicants for consents to discharge have the right of appeal if they are dissatisfied with the Agency’s decision; most of these appeals are dealt with by the Planning Inspectorate, an executive agency of the DETR. In Scotland control is the responsibility of the Scottish Environment Protection Agency (SEPA), and most appeals are dealt with by the Scottish Office. In Northern Ireland the Environment and Heritage Service is responsible for controlling water pollution.　　In 1997, there were 4,717 cases in England and Wales of discharges exceeding their consented limits, including a number of offences by water companies discharging insufficiently treated sewage. The majority of these breaches did not cause any significant environmental damage. However, the Environment Agency did bring 65 cases to court, of which 61 were successful, resulting in fines ranging from ￡ 440 to ￡ 12,000 and one prison sentence of two months. In Scotland, there were 2,734 pollution incidents in 1997; SEPA seeks prosecution in all significant cases.　　In 1997 and 1998, the Government introduced statutory Environmental Quality Standards (EQSs) for 33 substances in water. The new regulations give legal force for the first time to standards for some of the most dangerous pollutants found in the aquatic environment.　　In the UK, 96 percent of the population live in properties connected to a sewer, and sewage treatment works serve over 80 percent of the population. In England and Wales, the water industry is committed to an investment programme of some ￡ 11,000 million over ten years for improvements to water quality. Progressively higher treatment standards for industrial waste effluents and new measures to combat pollution from agriculture are expected to bring further improvements in water quality. In Scotland, responsibility for the provision of all water and sewerage services lies with three Water and Sewerage Authorities, covering the north, east and west of the country.
