Foreword
If you work at a drinking water utility, this book is written for you. It is a practical
step-by-step approach to the complex topic of drinking water quality.
It will show you how to be proactive on water quality issues through routine
monitoring of the distribution system and will help you prevent the devastating and
costly effects of:
• Falling out of compliance with the Lead and Copper Rule
• Developing pinhole leaks in water service lines and private plumbing
• Leaving the water distribution system vulnerable to microorganisms
• Experiencing unwanted side effects from treatment chemicals
• Adding the wrong water treatment chemical or using the wrong dosage
This book will put you on a path to well-defined and measurable control of water
quality.
Although proactive monitoring costs money, having water quality problems is
even more costly! This book describes how proactive monitoring is both beneficial
and economical.

Preface
Monitoring the water quality in a distribution system is a daunting task. A typical
water distribution system is chaotic and complex, with greatly varying piping con-
figurations, water flows, chemical reactions, and microbiological activity. This book
simplifies the monitoring task. It describes a method to routinely monitor the water
distribution system in a controlled, standardized, and accurate manner.
The monitoring approach pays off. It is, most likely, more cost effective to proac-
tively track and respond to water quality parameter values rather than retroactively
remedy water quality problems. This will be shown in Chapter 5 in an economic
analysis after:
• Introducing you to some basic water chemistry concepts (Chapter 1)
• Describing the steps to routine monitoring (Chapter 2, Chapter 3, Appendix
A, Appendix B)
• Laying out the details of a standardized monitoring station (Appendix D)
• Explaining a straightforward graphical approach to data analysis and water
quality control (Appendix E)
• Demonstrating successful use of the monitoring technique (Chapter 4)
The profound understanding of water quality that results from using this method
will help all water utilities—large and small—to comply with changing drinking
water regulations and to deliver safe and economical drinking water to consumers.
