| Summary: | Copper corrosion in water distribution systems has been critically assessed over the
past decades, mainly as a result of stricter regulatory standards for potable water and wastewater such as United States Environmental Protection Agency (USEPA) Lead and Copper Rule and wastewater regulations as well as rising consumer expectations. Recently, copper corrosion has evoked public concerns due to occurrences of Blue Water (blue, green or blue-green in color) by copper plumbing in water supply. Blue water or copper corrosion by-product release is always related to the release of high concentrations of copper precipitates under conditions expected to induce passivity and adherent corrosion products on the copper surface. Thus far, the cause of copper corrosion is still not completely understood as its occurrence is irregular. |
