Army installations must comply with the increasingly stringent drinking water quality standards enacted at the Federal level and enforced by state regulations. Much attention has focused on the costly remediations required when the allowable level of lead in drinking water is exceeded. This issue plays a significant role in the search for cost-effective ways to ensure that drinking water at Army installations meets all standards for quality and compliance with applicable laws. This study evaluated the effectiveness of three chemical treatments versus a control for inhibiting lead corrosion under a variety of water quality parameters in both the laboratory and field. This study also tested whether a coating or lining could be applied, in-situ, to existing small diameter pipes or tubes to mitigate corrosion and plumbosolvency and eliminate the need for chemical treatment. Recommendations were made to incorporate the results of the chemical treatment study into existing Army guidance documents, and also to further study application of in-situ coatings.
