Assessment of Inorganics Accumulation in Scales and Sediments

WaterRF #3118.

The purpose of this project was to investigate the accumulation of regulated inorganic contaminants and naturally occurring radionuclides in distribution system pipeline scales and sediments. The project investigated the mode of occurrence and possible correlation of inorganics/radionuclides accumulation with water qualities, pipe materials, and water sources, etc. Field studies were conducted to extract sediment and piping materials for detailed analyses using standard and novel analytical techniques. The project will help utilities predict those distribution systems particularly at risk from this type of contamination problem, identify management strategies, and determine potential public health implications and regulatory consequences.
