Product Description:

Identifies the best technologies or other means that are generally available, taking costs into consideration, for inactivating or removing microbial contaminants from surface water and groundwater supplies of drinking water. More specifically, it discusses water treatment technologies to be used by community and non-community water systems in removing turbidity, Giardia, viruses, and bacteria.
Foreword
This book identifies the best technologies or other means that are generally
available, taking costs into consideration, for inactivating or removing microbial contaminants from surface water and groundwater supplies of drinking water.
For municipal officials, engineers, and others, the book provides a review of alternative technologies and their relative efficiency and cost. More specifically, it discusses water treatment technologies which may be used by community and noncommunity water systems in removing turbidity, Giardia, viruses, and bacteria from water supplies. While most of the book covers surface water supplies, a brief discussion of disinfection technologies and costs for groundwater supplies is also provided, since disinfection is the best available technology for groundwater systems to comply with coliform regulations.
The technologies and actions available to a community searching for the most economical and effective means to comply with microbiological regulations
include modification of eXisting treatment systems; installation of new treatment systems; selection of alternate raw water sources; regionalization; and documenting the existence of a high quality source water while implementing an effective and reliable disinfection system, combined with a thorough monitoring program, and maintaining a continuing compliance with all drinking water regulations.
It is not the intent of the USEPA to require any system to use a particular
technology to achieve compliance with proposed treatment regulations. Instead, the responsibility is retained by the individual water systems to select one or more procedures that are optimal for their particular water supply situation. Whatever technology is ultimately selected by a water supplier to achieve compliance with the requirements must be based upon a case-by-case technical evaluation of the system's entire treatment process, and an assess ment of the economics involved. However, the major factors that must be
considered include:
• Quality and type of raw source water
• Raw water turbidity
• Type and degree of microbial contamination
• Economies of scale and the potential economic impact on the community being served
• Treatment and waste disposal requirements
Some methods are more complex or more expensive than others. Selection of a technology by a community may require engineering studies and/or pilotplant operations to determine the level of removal a method wiII provide for that system.
Alternative technologies for the removal of microbial contaminants and turbidity are identified because of their adaptability to treatment of drinking water supplies. It is expected that after development and pilot-scale testing, these methods may be technically and economically feasible for specific situations.
The information in the book is from Technologies and Costs for the Treatment
of Microbial Contaminants in Potable Water Supplies, by Jerrold J. Troyan
and Sigurd P. Hansen of CWC·HDR, Inc. for the U.S. Environmental Protection
Agency, October 1988.
The table of contents is organized in such a way as to serve as a subject index and provides easy access to the information contained in the book.
Advanced composition and production methods developed by Noyes Data Corporation are employed to bring this durably bound book to you in a minimum of time. Special techniques are used to close the gap between "manuscript" and "completed book." In order to keep the price of the book to a reasonable level, it has been partially reproduced by photo-offset directly
from the original report and the cost saving passed on to the reader. Due to this method of publishing, certain portions of the book may be less legible than desired.
