Abstract:
The National Rivers Authority is a public body, charged with the duty of improving the Water
Environment. Anglian is one of eight Regions. This report gives trends over the past 10 years in the chemical quality of rivers. We demonstrate that water quality has improved since last year and by 34 per cent since 1990. This is matched by an improvement in the biology. The biological quality is easily the best we have recorded and showed a net improvement since last year and a net improvement of 26 per cent since 1990. The causes of the improvements in river quality are better effluent quality, and river flows that were higher than those from 1990 to 1992. The number of reported Pollution Incidents increased by 5 per cent from 1993 to 1994 though again there were fewer of the more serious incidents. The increase from 1992 to 1993 was 4 per cent. A few sites failed criteria for the Dangerous Substances Directive. We report on progress. We produced maps of 145 Protection Zones for the Groundwater Protection Policy. We advised the Government on the boundaries of Nitrate Sensitive Areas and Nitrate Vulnerable Zones. We outline the conclusions of the report by the National Audit Office on farm pollution. We report on our programme of 1500 Formal Visits for Pollution Prevention. We report trends for Bathing Waters since 1987. In 1994, six Waters foiled This is one more than 1993 and another setback since 1992. However the average levels of pollution have continued to improve steadily. We give trends for the performance of discharges since 1982. 97.8 per cent of the sewage treatment works operated by Anglian Water complied with their Consents, a little better than last year. We show how Consents have tightened since 1990. The number of enquiries of the Water Resources Act Register has increased steadily since it opened in 1985. There were 1282 in 1994, an increase of almost 40 per cent since 1993. We used River Quality Indices and the Laboratory Information Management System to ensure efficient use of our monitoring resources. We set up the NRA's National Centre on Toxic and Persistent Substances.
