Volume I. The author appears to be a biologist with a flare for mathematical models which is reflected in his approach to water pollution problems. If one of the purposes of the book is to consider waste water reuse a more scientific review of the water quality “criteria” should have been given for various uses in addition to public water supply such as recreation, shellfishing, agricultural and industrial. Table 8 on page 20 obviously is not criteria (limit for designated use) but rather “optimum goals.” Some of the water quality items are strange, for example, coliform MPN for drinking water on page 3 and temperature, page 71, since many natural waters above 80 F are optimum for swimming. Units, abbreviation and terminology in Chapter 3 should have been in the appendix and some of the definitions of terms such as “pollution,” “fecal coliforms,” coliform bacteria, and “BOD” could be tighter.
