This package includes targeted testing for C4, C5, C8 and other Perfluoroalkyl Substances (PFAS) most often associated with GoreTex®, Teflon®, StainMaster® carpets, Scotchgard®, and other flame retardants and non-stick products. While these synthetic compounds require special testing methods to analyze at very low detection levels, PFAS are ever more prevalent in the environment and are notorious for bio-accumulation in animal and human body tissues. Tap Score testing of PFASs detects contaminants down to 10 Part-Per-Trillion concentrations. The EPA target for PFAS in drinking water is currently 70 Parts-Per-Trillion.
This test utilizes USEPA Method 537 (version 1.1) and includes branched and straight chained isomers.
What does this test for?▾
This test includes analysis of the following compounds using EPA Method 537 for home sampling and laboratory testing
- Perfluorooctanoic acid (PFOA)
- Perfluorooctane sulfonate (PFOS)
- Perfluoroheptanoic acid (PFHpA)
- Perfluorononanoic acid (PFNA)
- Perfluorobutane sulfonate (PFBS)
- Perfluorohexane sulfonate (PFHxS)
- Perfluorodecanoic acid (PFDA)
- Perfluorohexanoic acid (PFHXA)
- Polytetrafluoroethylene (PTFE)
- Fluorotelomer alcohol 8:2 (PTOH)
What are PFA/PFOS/PFOA?▾
The PFCs (Perfluorinated Chemicals) listed above are manufactured for use in daily products globally. They have been used in the production of Teflon and other plastics. Humans are exposed to PFAS in small quantities through packaging and other plastic products imported from abroad. Most over-exposure results from ingesting contaminated water through irresponsible disposal of wastewater from industries as was the case in Hoosick Falls, NY.
PFOA, also known as C8 (because it has 8 carbons), is classified as a possible human carcinogen, Group 2B by IARC, a subsidiary/adviser of WHO. PFOA is a very stable compound and persists in the environment indefinitely.
The EPA just released an advisory for PFOA and PFAS in July 2016 setting the lifetime HA for PFOA at 0.07 ug/L (70 parts per trillion, ppt). EPA also released a PFAS action plan in 2019, but no federal enforcement yet exists to deal with the large range of PFCs in the environment and potentially in drinking water.
State limits for PFC compounds in drinking water are often lower than EPA's advisory and changing quickly as new science emerges.
Connecticut recommends a 70 ppt limit for PFOA, PFOS, PFHxS, PFNA, PFHpA combined. New Jersey has proposed a limit of 13 ppt for PFOS (2018) and 14 ppt for PFAS (2017). Minnesota has proposed a limit of 15 ppt for PFOS (2019); 35 ppt for PFOA (2017); 47 ppt for PFHxS (2019); 2 parts per billion for PFBS (2017).
While U.S industries have voluntarily stopped use of PFOA and PFOS, the stability and hence the persistence of these compounds makes them a lifetime concern. They are present in products imported to the US and other PFCs are in production to replace them (e.g. other PFCs). They are found in water, ambient air, and occasionally indoor dust.
What's in the box?▾
Testing packages include sterilized water sampling vials, return shipping label, testing instructions, sample information card, and foam padding for the contents.
Once the lab receives your box, your personalized Tap Score Report will arrive by email within 14 business days.
Each report includes analysis for specific numerical concentration levels of each contaminant and details about the potential sources and health effects associated with each parameter. We are not medical doctors and Tap Score does not provide medical advice. For medical concerns always consult your doctor. Because this testing package requires you to collect the water sample, it is not meant for state or federal compliance water testing. If you or your organization requires compliance with State or Federal Law, or compliance with a particular regulatory requirement then you must contact our support team.
