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 list marks this certification "Reciprocidad" (granted by reciprocity). "Químicos" names no analyte, so no nitrate, metals or VOC certification is shown. Ask the lab.

Around this lab: Los Angeles County, CA

• Private wells: about 30,311 people, 0% of Los Angeles County’s 10,170,292 residents (USGS, 2015); rank 17 of 58 counties in California by people on wells.

• EPA radon zone (indoor air): Zone 2: moderate potential (average indoor radon may be between 2 and 4 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Arsenic above 10 µg/L (USGS model): about 17,244 private-well users (95% range 12,915 to 22,850; 2010 base), rank 1 of 58 in the state. A screening estimate, not a measurement of any well.
• Older homes (Census ACS 2020–2024): 70% of 3,650,466 housing units were built before 1980, above the state share of 56%. 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): 131 public systems serving this county reported EPA UCMR 5 results; 54 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.
