Abstract

Assesses the prevalence of regulated naturally occurring inorganic compounds that are believed to accumulate in distribution system pipeline scales and sediments and residential/institutional plumbing systems. Investigates the mode of occurrence and possible correlation of inorganic compounds accumulation with water qualities, pipe materials, and water sources, etc. Also develops a conceptual model that could predict those distribution systems particularly at risk from this type of contamination problem, and indicates regulatory and human exposure consequences.
