Term Identity
What the term means in an annual report
Cyanide in this regulatory context means the free-cyanide form named by the federal drinking-water standard.
Why it may appear
Systems report cyanide monitoring to summarize the named report-period result under the inorganic-contaminant rule.
How it may be printed
Reports may shorten the label to Cyanide and show MCL and MCLG fields, a result and range, a unit, a sample period, and printed status.
- Other names you may see
- Cyanide; Cyanide as free cyanide
- Common report labels
- Cyanide; Cyanide (as free cyanide)

Regulatory Context
How to read the applicable rule language
Use this Cyanide context to read a report's printed fields; it does not replace the report or the current official rule.
Framework
The federal entry is specifically cyanide as free cyanide. The site does not broaden a generic label printed in one report into unsupported chemical or exposure claims.
Limit or program terms
- MCL
- MCLG
Units and source context
Read the report's unit, result, range, period, and printed criteria without converting the value unless a source-bound review supports it.
What this page does not duplicate
A listed cyanide result is not automatically a violation, advisory, or current household finding.
No standalone numeric limit table is rendered here. Read the source report's printed criterion and the current official source together.
Interpretation Boundaries
What a listed result does not establish
These Cyanide boundaries apply to every report row connected to this explainer.
Household-level boundary
A system annual-report cyanide result does not establish current conditions at a particular tap.

Lead
Lead is regulated through a treatment technique and tap-sampling action-level framework. A report row does not describe every tap or identify a home's plumbing.

Nitrate
Nitrate is a regulated inorganic contaminant. Report labels often specify that the result is measured as nitrogen, and that basis must remain attached to the value and unit.

Copper
Copper is regulated with lead under a treatment-technique and tap-sampling action-level framework. Plumbing and corrosion control can influence results.
