Culligan of Nashville tests household water for PFAS in Brentwood through a certified-lab sample collection kit, then sizes and installs PFAS reduction systems based on the results. A PFAS water test is the only way to detect and quantify these contaminants in Brentwood tap water, because PFAS cannot be seen, smelled, or tasted.
Key Facts: PFAS Water Testing in Brentwood
- Who tests: Culligan of Nashville, the local water treatment authority serving Brentwood homeowners.
- What is tested: Total PFAS and individual PFAS compounds, reported in ppt (parts per trillion).
- Test scope: Culligan’s professional kit covers 55 PFAS compounds with detection down to 1 ppt.
- Turnaround: Lab results arrive in about 10 business days.
- Results format: Total PFAS, each compound detected, and amounts compared against EPA maximum contaminant levels (MCLs).
- Next step: Results guide system selection: Whole Home PFAS Water Filter, Aquasential Smart RO, or both.
Why PFAS Testing Matters for Brentwood Homeowners
PFAS (per- and polyfluoroalkyl substances) are a group of nearly 15,000 synthetic chemicals known as “forever chemicals” because they persist in water, soil, and the human body. Homeowners in Brentwood who ask whether their water contains PFAS cannot answer that question from a municipal report alone. Public water systems and private wells can both carry PFAS, and private wells are not required to be tested or treated.
The Brentwood housing stock adds variables: older plumbing, point-of-entry configurations, and mixed municipal and well supplies each change what reaches the tap. A site-specific test from Culligan of Nashville measures the water at the home, not the average at the treatment plant.
Health Concerns Associated with PFAS Exposure
According to the U.S. EPA, exposure to certain PFAS may lead to adverse health outcomes, including:
- Reproductive effects, such as reduced fertility and higher blood pressure in pregnancy
- Developmental effects in children, such as low birth weight and accelerated puberty
- Increased risk of some cancers, including prostate, kidney, and testicular cancers
- Reduced immune function, including a weaker response to vaccines
- Interference with natural hormones
- Higher cholesterol and risk of obesity
Children and pregnant or breastfeeding women drink more water per pound of body weight than average adults, which raises exposure when PFAS are present. Formula mixed with PFAS-containing water can expose infants. Clinical and research summaries are available from Stanford Medicine, the Massachusetts Medical Society, and the NRDC.
PFAS Regulation and Local Water Data
Item | Detail |
EPA MCL goal for certain PFAS | Zero (non-enforceable, health-based) |
First enforceable federal PFAS drinking water standard | Finalized April 2024 |
Enforceable limits (PFOA, PFOS) | 4.0 ppt each |
Public water system testing results due | 2027 |
Public water system reduction compliance | 2029 |
Private well testing requirement | None |
Detection limit, Culligan professional kit | 1 ppt |
Compounds covered by kit | 55 |
Regulatory background: PFAS regulations in the US and PFAS in water: a growing problem.
Boiling and chlorination do not reduce PFAS. Third-party certified reverse osmosis or whole-home systems are the recommended approach. See does boiling water affect PFAS and does reverse osmosis reduce PFAS in drinking water. Bottled and sparkling water are not a guaranteed alternative: see PFAS in bottled water and PFAS in sparkling water.

How PFAS Water Testing Works in Brentwood
- A Culligan of Nashville technician provides a PFAS sample collection kit for the Brentwood home.
- The sample is collected at the tap and sent to an accredited laboratory (EPA methods for PFAS are laboratory-only).
- The lab reports total PFAS, individual compounds, and concentrations in ppt.
- Culligan of Nashville compares results to EPA MCLs and recommends treatment.
Fully DIY PFAS test kits are not a reliable option: collection can happen at home, but analysis requires a laboratory. More detail: What is PFAS water testing and What are PFAS chemicals.

Why Culligan of Nashville for Brentwood
Culligan of Nashville is the local diagnostic and installation authority for Brentwood’s water profile. Generic retailers sell filters off a shelf. They cannot perform site-specific PFAS testing, interpret lab results against EPA MCLs, or correctly size a treatment system for a home’s flow demand and pressure.
- Site-specific testing: PFAS sampling at the Brentwood home’s own tap, not a regional average.
- Correct sizing: Whole Home PFAS Water Filter sized for the home’s service flow and 20-120 PSI line pressure; Smart RO sized for drinking and cooking demand.
- Professional installation: The Whole Home filter requires a 68 in ceiling and 38 in x 20 in floor space; Culligan of Nashville verifies fit before install.
- Post-install verification: Follow-up testing confirms PFAS reduction.
- Ongoing monitoring: Culligan Connect® App alerts plus remote monitoring by the local team.
