The EPA's Maximum Contaminant Level for cadmium is 0.005 mg/L, with a Maximum Contaminant Level Goal of the same value. The EPA's own published health effects data cites kidney damage as the concern from long-term exposure above this level.
Cadmium typically enters water from corroding galvanized plumbing, industrial or metal-processing discharge, or runoff from some fertilizers used in agricultural areas.
Illustrative water-testing concept.
Watch For This
Signs to Look For
Older galvanized plumbing, which can corrode and release cadmium over time
A property near industrial, metal-processing, or agricultural fertilizer activity
No reliable taste, smell or color indicator at regulated levels
No recent comprehensive heavy-metals water test
How We Fix It
Reverse Osmosis System
Reverse Osmosis System
Reverse osmosis filtration reduces cadmium as part of the broader range of dissolved metals its membrane is built to address.
Note: this is addressed by our reverse osmosis drinking-water system specifically — our whole-house filtration systems are not designed or certified to remove it.
