Environmental Engineering

INTRODUCTION -- This is a summary of a 1996 college textbook (Sincero & Sincero, 1996), Environmental Engineering: A Design Approach, by Arcadio P. Sincero, Sr. and his wife, Gregoria A. Sincero. Since there is one bibliographic reference, because the authors' surnames are the same and are fairly long, and to save space in this precis of the text, the remaining citations will be formatted either as:(S&S, 1996) or (S&S, 1996, pp. 47-52).

1. Introduction -- The six-page opening defines environmental engineering as "the application of engineering principles, under constraint, to the protection and enhancement of the quality of the environment and to enhancement and protection of public health and welfare," as distinguished from older U. S. and British connotations of sanitary engineering and public health engineering (S&S, 1996, p. 2).

Next, in several sentences each, the 14 chapters of the book are summarized (S&S, 1996, pp. 2-4). At the end, four episodes are recounted of bacterial or chemical onslaught in urban areas of the world, which environmental engineers eventually controlled. These notorious "environmental tragedies" were two air pollution incidents, a hazardous waste fiasco, and a serious bacterial pollution of a drinking water well (S&S, 1996 pp. 4-6).

2. Environmental Chemistry and Biology -- The first technical chapter addresses basic facts, processes, and scientific tenets to descr

computer simulators, with equations of processes for each element of a water body, making repetitive calculations for all elements from field data and coefficients supplied by the user. Stream processes stressed are dispersion (S&S, 1996, pp. 171-80); "transformations," such as settling, microbial degradation, or volatilization (S&S, 1996, pp. 180-87); and dissolved oxygen modifications in a mildly polluted stream (S&S, 1996, pp. 187-98). The authors' stream model (S&S, 1996, p. 192)--on an attached CD-ROM disk--was not opened or tested here. Air and groundwater models (S&S, 1996, pp. 198-217) given tediously, include all x-, y-, and z-varying or invariant terms. 6. Conventional Water Treatment -- The longest and most appropriately directed chapter for the undergraduate describes treatment of public water supplies. Design criteria and computations are given for settling tanks (S&S, 1996, pp. 227-42) and granular-media filtration (S&S, 1996, pp. 242-60), and for the processes of coagulation (S&S, 1996, pp. 260-65), flocculation (S&S, 1996, pp. 265-73), softening (calcium/ magnesium removal, primarily) (S&S, 1996, pp. 273-86), and disinfection (S&S, 1996, pp. 286-91). 7.
