The drinking water community shares its water systems with a world of microscopic living creatures. These creatures may contribute to numerous operational challenges, from problems in source water through finished water, including encrustation or corrosion within the water system and water quality problems at the customer's tap. When water treatment problems arise due to these organisms, it is often difficult for an operator to locate help.
This manual provides information regarding nuisance organisms, the problems they cause, treatment options, and references to literature resources. It is intended to be a "first stop" toward finding answers. This third edition replaces AWWA Manual M7, Problem Organisms in Water: Identification and Treatment, 2nd edition. This complete revision of AWWA Manual M7 stems from the results of the 1989 AWWA Survey of Nuisance Organisms (appendix A) that demonstrated a need for information to help identify and control these organisms.
Note: Because it contains color graphics, the digital edition of M7 is a large file and may take several minutes to download.
