Description
The objective of this study was to use a spatial and temporal methodology to test the possible correlationsbetween lead leaching in water distribution systems (WDS) and other hydraulic and water qualityparameters. The water quality parameters and lead sample data were evaluated by integrating spatial dataanalysis and geostatistics with geographic information systems (GIS) and simulation results from GIS-assistedwater quality models. The lead sampling data were processed using geocode tools, and thecorresponding map was spatially joined with water quality model output, e.g., water ages, and otherspatially and temporally distributed parameters, such as nitrate (NO<sub>3</sub><sup>-</sup>) and heterotrophic plate counts(HPC). Using spatial analysis and geostatistics, these data were used to test for the hypothesis on leadleaching and water ages, and the influence of other water quality parameters. This paper is a summary ofthe study that will provide utilities with an overview of using spatial and temporal methodology to test theinfluences of hydraulic parameters and other water quality parameters on lead leaching in WDS. Includes 35 references, tables, figures.
