Groups as written on the state list (1)
- Bacteriología (bacteriological analyses of drinking water)
- 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". 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.

Around this lab: Ponce Municipio, PR
- Private wells: about 0 people, 0% of Ponce Municipio’s 149,028 residents (USGS, 2015); rank 10 of 78 counties in Puerto Rico by people on wells.
- Older homes (Census ACS 2020–2024): 63% of 69,741 housing units were built before 1980, above the state share of 53%. Homes built before 1986 are more likely to have lead solder or fittings, so test tap water for lead there.
- PFAS in public water nearby (public supply, not your well): 3 public systems serving this county reported EPA UCMR 5 results; 2 had a PFOA or PFOS sample at or above 4.0 ng/L.
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 Puerto Rico certification program.
