GenX and PFAS Water Test (EPA 537.1)
$ 449.00 $ 540.00 Save 17%
This water testing package includes targeted laboratory analysis for PFAS compounds & GenX in drinking water. GenX is otherwise known as chemical compound Hexafluoropropylene Oxide Dimer Acid (HFPO-DA) CAS # 13252-13-6. GenX has gained attention in recent years, after the widely reported chemical spill at the Chemours Fayetteville Works in North Carolina, GenX has subsequently been detected in nearby water supplies and is therefor a cause for concern.
This test is for anyone who wants a private laboratory to determine whether traces of the PFAS compounds including HFPO- DA, (sometimes referred to as "Gen X" or "C3 dimer") are present in their drinking water.
GenX is a synthetic compound that requires a special testing methods to analyze at very low detection levels. The role of GenX in human health is relatively unknown still but due to it's close relationship with PFAS compounds, it is assumed to bio-accumulate in animal and human body tissues.
Tap Score testing of GenX and PFAS in drinking water includes laboratory analysis method: EPA 537.1 utilizing isotope dilution. The Tap Score reporting limit for GenX and PFAS in drinking water is 2 parts per trillion (ppt).

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.
