Description / Abstract:

Introduction

In 1989 the Organisms in Water Committee of the American Water Works Association (AWWA) conducted a survey to determine problems that water utilities encounter due to organisms in water. Of the 80 systems surveyed, only 7 indicated that they experienced no problems due to organisms in water. The other 73 systems had their hands full. These problems went beyond finding low levels of coliform bacteria in routine monitoring samples. The difficulties were related to "nuisance organisms," microorganisms that cause problems with plant operations or with customers because of undesirable tastes, odors, color, or their mere presence in what is supposedly a clean glass of water.
