This paper reports the results of a corrosion inhibitor screening evaluationconducted to assess alternative inhibitor formulations performed as part of Pinellas CountyUtility's (PCU's) Water Blending Facility (WBF) Project. The investigation evaluated severaldifferent inhibitors for metal release control in the Pinellas County Water System (PCWS) underreal-time variable water supply conditions. Field-testing was performed using electrochemicalnoise (EN) equipment at the S.K. Keller Connector in northeastern Pinellas County fromSeptember 8, 2002 to February 3, 2003 and from November 21, 2003 to February 25, 2004 usingwater supplied at the PCU's point of connection with the regional supplier, Tampa Bay Water(TBW). Differences in corrosion protection was noted among the inhibitors. Inhibitor reversionrates occurred in neat solution and generally increased with increased temperature. Thisdocument presents an overview of a study investigating inhibitor treatment of a variable blend ofchloraminated ground, surface, and desalinated water. Includes 12 references, tables, figures.
