AWWA WQTC71528

While the approach is not new, the application of the analysis and interpretation of leadprofile data contribute much needed information on the occurrence and potential control oflead in well-buffered groundwaters, a water quality type for which limited but somewhatunexpected results have been observed in other studies. For a system in which 20 to 40% ofthe residential and non-residential premise plumbing samples exceeded the lead action level,this study was critical for documenting the extent and magnitude of lead occurrence, and assessing the feasibility of eliminating lead from the system to control lead measured at thetap. Water from a groundwater system serving the city of Guelph, located in southwest Ontario, Canada, is the focus of this study. Alternatives to chemical treatment to control lead at the tap are being considered by the City,including lead service line (LSL) replacement. To assess the feasibility of LSL replacement for corrosioncontrol, the city initiated a Lead Profiling Study that examined the impacts of partial and fullLSL replacement on reducing lead. Results from this effort are presented in this paper. Includes 3 references, tables, figures.
