Terrebonne Parish Consolidated Waterworks District #1 Laboratory

Looks like a utility or municipal lab

Judging by the name only (this is our label, not the state's). Labs like this usually test their own system. The state list does not say whether it takes samples from the public, so ask before you send one.

Around this lab: Terrebonne Parish, LA

• Private wells: about 92 people, 0% of Terrebonne Parish’s 113,972 residents (USGS, 2015); rank 64 of 64 counties in Louisiana by people on wells.

• EPA radon zone (indoor air): Zone 3: low potential (average indoor radon may be less than 2 pCi/L). EPA says the zone map should not decide whether one home needs testing.
• Older homes (Census ACS 2020–2024): 47% of 47,392 housing units were built before 1980, about the same as the state share of 46%. 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; 0 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 Louisiana certification program.
