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*').

RIDOH lists "Potable water microbiology" for this lab but names no organism or method, so bacteria is shown as a certified group, not a named test (the drinking-water microbiology test is total coliform / E. coli). Ask the lab. RIDOH lists "PFAS" for this lab without saying whether it covers drinking water or which PFAS compounds, so PFAS is shown as a certified group. Ask the lab which drinking-water PFAS method (EPA 533 or 537.1) it runs. RIDOH's out-of-state list gives certification categories only ("Contact the Certification Officer for specific analytes/methods"): organic and inorganic chemistry and radiochemistry name no analyte, so no nitrate, arsenic, lead, metals, VOC, uranium or radon certification is shown. Ask the lab.

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 Rhode Island certification program.
