Tests on the state list
This list does not break certification down by analyte. Ask the lab which tests it is certified for; the groups as written on the list are below.
Groups as written on the state list (1)
- Environmental Lead
- 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*').
"Environmental Lead" is RIDOH's certification for lead in environmental samples (paint, dust), not in drinking water. RIDOH lists no potable (drinking) water category for this lab. RIDOH prints the same phone number for Environmental Hazards Services (Richmond, VA), a lab in another state; confirm the number with the lab.

- EPA radon zone (indoor air): Zone 1: highest potential (average indoor radon may be greater than 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.

County figures describe where the lab is, not the lab. Sources: USGS 2015 water use and 2017 arsenic estimates, EPA radon zones, Census ACS table B25034 (2020–2024), EPA UCMR 5 (2023–2026); details and links on the sources page.
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.
