ABSTRACT
We are not accountants or economists, but we are business people as well as ground-water professionals. This also is not a treatise on ground-water economics. For more on that, we refer you to the emerging body of work on that subject. Entire shelves of books have been written on this subject. A good place to start is some of the discussion in the much-anticipated International Manual of Well Hydraulics, to be published by ASCE (www.asce.org). However, we refer you to several recommended sources in the following sections (cited in our recommended reading list). We are presenting enough material here to support a discussion of the economic value of a sustainable management (maintenance and rehabilitation) of well systems (Figure 3.1).
