INTRODUCTION

Reliable laboratory quality testing forms the basis for water quality control. Laboratory test results make it possible for operators to evaluate and optimize plant performance in the following ways:

• Results from water testing help the operator to know and to document water quality conditions throughout the plant.

• Laboratory analyses form a basis for selecting operational procedures and chemical treatment and then for evaluating the effectiveness of changes to the system.

• Logging data and reviewing trends provide the opportunity to identify potential problems before they affect water quality.

• Reliable water quality testing forms the basis for regulatory compliance and ensures the best possible quality drinking water for the community.
