For greater recreational potential of stripmine lakes, certain fundamental limnological information and the unique water chemistry resulting from leaching of substances contained in the cast overburden of the lakes were investigated. Increasing levels of dissolved oxygen and decreasing concentrations of dissolved substances showed environmental trends in surface waters. These tendencies were somewhat obscured by differences in the annual cycles of stratification, four of the lakes proving to be unexpectedly meromictic. Biological changes associated with increasing pH included increasing diversity and increasing homeostasis. Both pH and circulation patterns (meromixis vs. holomixis) influenced biomass, and bottom fauna was further limited by the steep-sided basin form. All stripmine lakes had much higher solute concentrations and lower biological diversity than a small local non-stripmine reservoir studied as control. Sport fishing in stripmine lakes could be improved by management techniques.

Acidification is a universal problem at all mining sites in which oxygenated water comes in contact with sulfide minerals or other reduced sulfur compounds. An International Workshop was held in September 1995 at the Department for Inland Water Research of the UFZ-Centre for Environmental Research in Magdeburg on the limnology of lakes created by open-cast lignite mining, emphasizing the often observed geogenic acidification after oxidation of pyrite. The volume has 25 chapters including a chapter with results of group discussions about the topics mentioned above and further problems that were identified during the meeting. The monograph gives a baseline of the state of science on the worldwide problem of geogenic acidification of lakes following human mining activities.

Over the last century the discharge of crude or partially treated sewage has probably been the most widespread, most documented and certainly the best understood form of pollution entering the aquatic environment. In the past two decades, however, there has been an increasing public aware ness of the potential hazards that exist from the contamination of the freshwater environment by toxic substances associated with the mining industry. World demand for minerals has intensified the exploitation of natural resources. In most western and newly developed countries significant mining proposals are now strenuously regulated to protect the environ ment. These involve economic and legislative measures and the use of appropriate control technologies. This concern will undoubtedly continue to spread worldwide requiring a programme of enlightened environmental protection management policies and practices for the future. This book has been prepared as a synthesis of our current understand ing of the effects of various heavy metals and acidic discharges likely to contaminate the freshwater environment as a direct result of mining activities. The review is based upon the dissertations of former BP spon sored students who were engaged to provide a better scientific understand ing of the causes of environmental problems associated with this industry. It gives us great pleasure to publish this information for use and appli cation by a wider audience as part of the contribution of The British Petroleum Company p.1.c. to European Year of the Environment.
