This monograph provides an international perspective on pit lakes
in post-mining landscapes, including the problem of geogenic
acidification. Much has been learned during the last decade through
research and practical experience on how to mitigate or remediate
the environmental problems of acidic pit lakes. In the first part
of the book, general scientific issues are presented in 21
contributions from the fields of geo-environmental science, water
chemistry, lake physics, lake modeling, and on the peculiar
biological features that occur in the extreme habitats of acidic
pit lakes. Another chapter provides an overview of methods
currently used to remediate acidic pit lakes and treat outflowing
acidic water. The second part of the book is a collection of
regional surveys of pit lake problems from three European countries
and Australia, and case studies of various individual
representative lakes. A final case study provides an innovative
approach to assessing the economic value of new pit lakes and
balancing the costs and benefits, a valuable tool for decision
makers.

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.
