Nickel
Often associated with taps, fittings and plated surfaces.
What is Nickel?
Nickel is a metal used widely in alloys, plating and stainless steel.
Why test for it?
Nickel is a useful indicator of contributions from fittings and taps, and is frequently reported alongside copper and lead.
Where can it come from?
- Chrome-plated taps and fittings
- Stainless steel components
- Natural geology
How is it measured?
Determined by ICP-MS, reported in µg/L.
What does my result mean?
First-draw samples often show higher nickel than flushed samples where plated fittings are present.
