This slide presentation outlines information on corrosion impacts in distribution systems served by multiple source waters. Topics covered include: corrosion control approaches; corrosion control monitoring; approach; water quality variations; system variables; water quality comparison; corrosion indices; buffer capacity; corrosion rate calculation; coupon testing; pipe loop analysis; variations in copper corrosion rates; comparison of copper and lead corrosion rates; variations in ductile corrosion rates; variations in steel corrosion rates; summary of metal corrosion rate testing; qualitative comparison of surface
characteristics of copper coupons; comparison of copper release
and coupon corrosion rate; comparison of copper release and Langelier Index; comparison of copper release and Larsen's ratio; pipe loop results - groundwater, no inhibitor; hydrogen sulfide impacts on chlorine demand; variations in Langelier Index from multiple well sources; distribution system variations in sulfate and chloride from multiple well sources; variations of Langelier Index in distribution system; increase in copper and iron due to residential plumbing (hot water); and, qualitative comparison of surface
characteristics - black water
particles.
