New Paper on Lead and Copper Corrosion in Water Distribution Systems

This study applied geographic information systems (GIS) and a hydraulic model of distribution systems to test the influences of pipe material, pipe age, water age, and other water quality parameters on lead/copper leaching.

(RALEIGH, NC – May 14, 2014) – Michael Wang and Weidong Zhang are co-authors of a new paper recently published in Journal of Environmental Engineering.

The paper, titled “Using a GIS and GIS-Assisted Water Quality Model to Analyze the Deterministic Factors for Lead and Copper Corrosion in Drinking Water Distribution Systems” provides utilities with an overview of using a spatial and temporal methodology to test the influences of hydraulic and water quality parameters on lead leaching in water distribution systems. With the methodology, utilities will be able to have a better understanding of the causative factors behind lead leaching in distribution systems and use their scarce resources to focus on high-probability areas for lead leaching.
