Document Type: Proceeding Paper

Part of: Environmental Engineering


A study has been conducted to determine the level of corrosion activity occuring on the U.S. Navy's potable waterlines on Guam. The study evaluated soil parameters including drainage, permeability, pH and resistivity and potential stray-current sources and their impact on corrosion activity. An empirical formula for predicting corrosion activity based on these parameters was developed. Also included are recommendations to other water system utilities who might be contemplating a system wide corrosion evaluation study.
