1. John Mather, chief geochemist at the British Geological Survey, warns that a third of our tapwater could exceed nitrate levels within a few decades.
2. In October 1989, after four years of dispute, the European Commission finally began its legal attack on the UK for allowing excess nitrate in the water supply of Norwich and Redbridge, and for illegal levels of bacteria and aluminium elsewhere.
3. Suffice it to say that ammonium nitrate-fuel oil is now the standard explosive for blasting and quarrying; the nitro-organics industry has shrunk and readjusted to a restricted role as a supplier of initiators and specialist explosives; and ammonium nitrate is now available in a kaolin-free "explosives grade".
4. Changes in nitrification caused by ammonium and nitrate deposition are blamed, and heathland soils have become richer in nitrogen and more acid.
5. At high deposition, nitrate is found leaching away because the soil processes and capacity of plants to take up nitrogen are exceeded.
6. On 20 July, the generally anti-government Guardian reported that "scientists at water authorities have been threatened with criminal proceedings if they talk about the costs of dealing with nitrate pollution."
7. Ammonium nitrate has three memorable properties.
8. The Draft Directive has adopted the same 50 mg/litre nitrate standard as the Drinking Water Directive and proposes the designation of "zones" that are "vulnerable" to being polluted with nitrate up to 50 mg/litre, either directly or indirectly.
9. The Nature Conservancy Council has officially advised the DoE that nitrate levels in rivers "of special interest" for conservation should not exceed 15 mg/litre and in lakes should not exceed 7.5 mg/litre.
10. The Commission noted that another letter from the UK dated 5 January 1989 had tried to make the case that "all supplies which presently exceed the nitrate admissible concentration will be brought into progressive compliance between now and 1995, all but two supplies complying by 1993".
11. The Department of the Environment (DoE) had foreseen difficulties with the Directive, and now asked the Department of Health for advice on nitrate levels, most probably so that the UK could argue for laxer standards.
12. The nitrate problem has taught us that to protect our drinking water, we must monitor the unsaturated zone.
13. Over 99 per cent of the population is connected to the public water supply receiving water with less than 50 mg/litre nitrate.
