This, in turn, may push asystem out of compliance with USEPA's 1991 Lead and CopperRule for system corrosion.If corrosion does increase, pH adjustment or the addition oforthophosphate as a corrosion inhibitor, can help control theproblem. No matter the situation, the authors stress the need forroutine monitoring of the system so that chemical levels can beadjusted appropriately in the event of corrosion.
