Copper-silver ionization

[1] Ionization can be an effective process to control Legionella in potable water distribution systems found in health facilities, hotels, nursing homes, and large buildings.

[4] Copper-silver ionization technology is recognized by the World Health Organization (WHO), the U.S. Environmental Protection Agency (EPA) to control Legionella within potable water distribution networks found in hospitals, hotels and other large type facilities.

[5] The British Health and Safety Commission regulates U.K. ionization, advising regular system monitoring to ensure ions reach all water circuits.

In response to this decision, five member states—Spain, the UK, Norway, Poland, and the Netherlands—have applied to the commission to allow for the continued use of copper as a biocide in their respective nations.

[9] Industry has responded by forming a Taskforce to ensure full and long term compliance with the regulatory issues facing copper in the EU.

[2] Over the long term, the presence of copper and silver ions destroy biofilms and slimes that can harbor Legionella, the bacteria responsible for Legionnaires' disease (legionellosis).

[2] It is possible to operate copper-silver ionization without exceeding the copper Action Level (AL) and silver secondary maximum contaminant levels (SMCLs) set by the U.S. Environmental Protection Agency in the Safe Water Drinking Act's Lead and Copper Rule (Title 40, Code of Federal Regulations, 40 CFR) in Part 141, Subpart I; and 40 CFR Part 143, respectively.
