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.

• 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*').

The Puerto Rico Department of Health lists this lab as "Certificado solamente para: Químicos (Reciprocidad)". The list names no analytes, certificate number or expiry date. The Puerto Rico list prints "115 South Illinois Street"; the lists of VA, PA, NY, IL, MO and others print 1115 South Illinois Street, Belleville, IL 62220 for American Water's Central Laboratory. The list marks this certification "Reciprocidad" (granted by reciprocity). "Químicos" names no analyte, so no nitrate, metals or VOC certification is shown. Ask the lab. The list also prints 239-0544, 233-4777 on the phone line. State printed as "Il".

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 Puerto Rico certification program.
