    Abstract

    The U.S. Army Construction Engineering Research Laboratory (USA-CERL)has employed an apparatus known as the Pipe Loop System (CERL-PLS) to evaluate corrosion and corrosion control programs in distribution water systems The apparatus uses multiple corrosion specimens of distribution system materials in direct contact with water under conditions simulating typical operation At two U S Army water treatment plants, the CERL-PLS was used to monitor corrosion of mild steel and galvanized steel piping materials in the distribution system and determine the effect of a corrosion inhibitor on the long-term corrosion rates At another Army installation, the effects of various water treatment options were studied for reducing lead dissolution from plumbing system materials The data presented demonstrate the successful application of a pipe loop system for optimization of water treatment for corrosion control and hence to meet drinking water quality standards.
