Abstract: This paper examines the important, and oftentimes dominant, role of particles in lead and copper corrosion by-product release from stagnant pipes. For copper pipes, orthophosphate generally reduced soluble copper levels ...

Abstract: In order to understand the redox chemistry of chromium at low concentrations

Abstract: The new Enhanced Coagulation Rule requires that drinking water utilities improve the removal of natural organic matter from their water. One common method of doing so is to “enhance” the performance of existing coagulation ...

Abstract: Because utilities with hard waters tend to have higher concentrations of arsenic, removal of arsenic via precipitative softening processes was investigated in the context of the more stringent proposed arsenic regulation. ...

Abstract: This four-year study evaluated the effect of phosphate inhibitors on the corrosion of iron pipes under extended stagnant water conditions. Study parameters included pH and alkalinity, age of the pipe, water stagnation time, ...

Abstract: The recently lowered arsenic maximum contaminant level will require numerous U.S. water utilities and agencies to monitor and treat for arsenic. This paper describes a new method that measures arsenic in drinking water ...
