• Group-level certification Certified for a parent group (e.g. 'Inorganics') that includes this analyte. Confirm the specific test with the lab.
• Partial group certification The list marks the group as 'Partial'. Confirm this analyte with the lab.
• Subcontracted The lab sends this analyte to another accredited lab (MDH 'X*').

Idaho drinking-water certificates on file: Inorganic chemistry, Organic chemistry, Radiochemistry (scanned certificates, read by OCR and checked; analytes left out where the scan could not be read with certainty). PFAS: DHW certifies the group "Per-and Polyfluorinated Hydrocarbons" on one line without naming each compound, so it is shown as a certified group.
