PREFACE, 2ND EDITION

Hailed on first publication as a straightforward, practical, and tothe-point account of wastewater principles, practices, and operations for general readers, students, and wastewater operators in training and for all levels of operators at any level of licensure, the second edition of Spellman’s Standard Handbook for Wastewater Operators, Volumes I, II, and III, continues to deal with the important aspects of wastewater operations and operator preparation for licensure examinations. In addition, based on constructive and helpful criticism of the original series, each volume has been upgraded, updated, and expanded to include additional pertinent information to help the user attain success by better preparing each qualified user for professional licensure.
