Abstract
The adverse effects of natural organic matter on copper corrosion by-produc t release to drinking water result from soluble complex formation, colloid mobilization/dispersion, and interference with aging processes that tend to decrease scale solubility. Organic matter can also reverse copper corrosio n by-product release to drinking water by (1) fueling microbial removal of oxygen, causing re-deposition of Cu(I) to the pipe wall, and (2) sorption o f soluble organic matter onto pipe surfaces during stagnation, which decrea ses the solution's complexation capacity for copper.
