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*').

The Puerto Rico Department of Health lists this lab as "Certificado solamente para: Bacteriología, Químicos y Radiológicos". The list names no analytes, certificate number or expiry date. The Department of Health lists this lab as certified for "Bacteriología" on its drinking-water (Sección de Agua Potable) list. Bacteriological drinking-water certification under the Safe Drinking Water Act covers the total coliform / E. coli tests, but the list names no organism or method, so bacteria is shown as a certified group, not a named test. Ask the lab which coliform test it runs. "Químicos" and "Radiológicos" name no analyte, so no nitrate, metals or VOC or 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 Puerto Rico certification program.
