Selection of a Site for Restoration

In this book it is our aim to review a variety of practical methods and procedures aimed at restoring acid waters, and to assess the liming project at Loch Fleet in the light of other selected examples. Some of these examples have already been identified in Chapter 1 (Table 1.1) and other examples, where there is relevant information, will be used throughout this text to develop the principles and practice of restoration. In reality, most of the methods that have been adopted have been based on applications of “lime” (as calcium oxide, calcium hydroxide, or calcium carbonate), or sometimes other materials such as magnesian limestones or calcium silicate slag. Some mention will be made here of the more limited experience reported for other materials and methods.
