The following treatments were evaluated in a pipe loop testing apparatus: adding orthophosphate using phosphoric acid; adding zinc orthophosphate; adjusting pH to 8.1 using sodium hydroxide; and adjusting pH to 8.7 using sodium hydroxide. The four corrosion control treatments tested in the pipe loops were evaluated based on the following criteria: performance for lead reduction; feasibility of implementation within regulatory and functional constraints; reliability in terms of operational consistency and continuous corrosion control protection; and cost.
