Water and Wastewater Examination Manual

V.Dean Adams

This new manual is an indispensable working lab guide and reference for water/wastewater quality analysis. Based on procedures from "Standard Methods" and "Methods for Chemical Analysis of Water and Waste (EPA)," and other pertinent references the Water and Wastewater Examination Manual is an excellent complement to these references-that you will want to keep at your fingertips. Written especially for use by water quality laboratory technicians and water/wastewater operators, managers and supervisors-who will use this practical manual every day. Procedures are included for parameters frequently used in water quality analysis.
