National Rivers Authority
The risk of river pollution from agriculture has increased over the last 50 years as farming practices have intensified. The storage and disposal of increasing amounts of both animal waste and silage liquors, and the use of pesticides and fertilisers, present significant risks to river water quality. For this report, the National Audit Office examined: the extent to which the National Rivers Authority has taken action against farm polluters and recovered the costs of cleaning up and restoring rivers in England; and the effectiveness of the efforts of the National Rivers Authority to reduce and prevent river pollution from farms in England.
Water Pollution Incidents in England and Wales, 1994
During 1994, over 35,000 pollution incidents were reported to the National Rivers Authority (NRA). More than 25,000 of these were later substantiated. These figures reflect a small increase in the number of incidents, while the most environmentally damaging Category 1 (Major) incidents fell from 331 to 229, a decrease of 31%. This report is the fifth annual analysis of pollution incident statistics for England and Wales issued by the National Rivers Authority. It details the substantiated incidents that occurred in the calendar year 1994, according to both source of pollution and type of pollutant. The construction industry, landfill and waste disposal operations were the greatest sources of industrial incidents, whilst dairy farming activities were the biggest source of agricultural pollution.
The Hydrology of the UK
The Hydrology of the UK assesses the changing hydrology of the UK, focusing on key issues that affect the fundamental hydrological processes and have important implications for water resource management, flood risk and environmental quality. The bookis divided into 3 sections: Section 1 examines the causes of change to the hydrology of the UK, including the impact of climate change, land use and geomorphological change, and dam construction. Section 2 assesses the effects of these pressures on UK rivers, goundwater, lakes, ponds, reservoirs and wetlands, looking at water quality, degradation, pollution and protection. Section 3 examines the responses of goverment organisations responsible for planning and management of water, including Environment Agencies, British Hydrological Society and the growing urgency for a World Hydrology Initiative. Change will continue to be a major feature of UK hydrology in the future. This book provides an understanding of the changing hydrology of the UK and the international scene today and looks to the needs for the future.
Abandoned Mines and the Water Environment
Pollution caused by abandoned mines is a rather specialized and local problem, but when and where it occurs its impact is enormous. South West England and Wales are especially affected by metal mines, such as Wheal Jane mine. British Coal's database lists some 10,000 abandoned mines around the country. This technical report discusses the environmental impact of minewaters, their chemistry and the deficiencies in current legislation. It identifies the way forward for the National Rivers Authority (NRA) in controlling such discharges.
The Changing Wildlife of Great Britain and Ireland
Periodic comprehensive overviews of the status of the diverse organisms that make up wildlife are essential to determining trends, threats and future prospects. Just over 25 years ago, leading authorities on different kinds of wildlife came together to prepare an assessment of their status of a wide range of organisms in Great Britain and Ireland in The Changing Flora and Fauna of Britain, also edited by Professor David L. Hawksworth CBE. Now, in The Changing Wildlife of Great Britain and Ireland, he has gathered together some of the original and also new contributors to review changes since that time and look to the future. Contributions range from viruses, diatoms, fungi, lichens, mites an...
