Included in the Extended Well Water Test

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?

testing by a certified lab

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)


PFOA is one of the many PFCs (Perfluorinated Chemicals) manufactured for use in daily products. PFOA (Perfluorooctonoic acid), is a man-made compound that is used in the manufacture of Teflon and other plastics, however, it’s not significantly present in the final product. Humans are exposed to PFOA in small quantities through packaging and other plastic products. 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 PFOAs in July 2016 setting the lifetime HA for PFOA at 0.7 ug/L (0.7ppb) and the value keeps approaching zero as more research emerges. Maine has set its limits to 0.1 ug/L.

While U.S is phasing out the use of PFOA and other PFCs, the stability and hence the persistence of these compounds makes them a lifetime concern. It’s found in water, ambient air, and occasionally indoor dust.

PFOA is neither included as an analyte in USGS’s NWQAP nor monitored by the EPA Aquatics Surveys.

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.

Informational testing

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.
