ABSTRACT
The computer programs included with this book are meant to be an integral part of the book and not an afterthought. Several programs, such as MFLASH and OFLASH, are flashcard systems written to ease the pain of remembering some of the basics necessary to understand the topics. Others, such as WATEVAL and ECOPLUS, may be used to evaluate the inorganic and organic constituents of waters, respectively. The calculations used in these programs, with the exception of the groundwater routine in ECOPLUS, are simple and easily done by hand. The computer version is, however, much more rapid and less subject to errors. An additional program, WATEQ4F (Ball et al., 1987), a water equilibrium program, is included for use in conjunction with the chapter on thermodynamics. The thermodynamics chapter is written primarily to aid in the use and understanding of the output from WATEQ4F.
