Tests on the state list

• Named on the official list The state list names this analyte (or a column for it) for this lab.
• 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*').

IEPA's chemistry list names no analytes; the 126 drinking-water analytes listed here are the lab's IL ELAP fields of accreditation in TNI LAMS (TNI01283), status Accredited. IEPA lists it under 'Secondary Labs' (accredited in Illinois on the basis of another state's NELAP accreditation). TNI LAMS records 'Commercial Samples: Yes' for this lab. Phone as printed; it may be wrong: TNI LAMS gives a 609 number for a lab in Dayton (South Brunswick), NJ, which mostly uses 732; IEPA's contact column prints a 732 number.

Before you send a sample

Call the lab to confirm it's currently certified for the exact test and method, that it accepts samples from homeowners, and how to collect and ship them. Bacteria samples have short holding times. Status can change between list updates. To check a status, contact the Illinois certification program.
