Regular site and lab monitoring of your copper and silver ion levels is essential to validate that your copper-silver system is functioning properly.  Monitoring also allows for more timely system adjustments and documentation for compliance.


Routine Monitoring

If levels of legionella colonization are controlled within acceptable ranges, or there are no known or suspected cases of Legionellosis, site analysis once per week and lab analysis once per month.

Reactive Monitoring

If levels of legionella colonization are undesirable, or there are suspected or known cases of Legionellosis, site analysis twice per week, and lab analysis weekly – preferably Monday.

Site Copper Testing

At least two samples need to be collected per system. More samples can be required depending upon the complexity of the plumbing system. One sample should be collected from the treated water supply, and the second should be from a location far away from the water supply (distal).

Lab Testing for Copper / Silver levels

Lab testing, which is the only way to accurately measure silver, reveals whether copper and silver levels are within optimal ranges and determines whether system adjustments are needed.
