PFAS Sampling Checklist

  1. Preparation:

    • Ensure all necessary equipment is clean and PFAS-free.

    • Use nitrile gloves at each sampling site.

    • Use PFAS-free soap for hand washing.

    • Verify that sample bottles contain the required preservatives; do not overfill or pour out excess liquid.

  2. Sample Collection:

    • Collect raw water samples from the well before any treatment system (if applicable).

    • Collect treated water samples from the point of entry (POE) or after the pressure tank.

  3. Handling:

    • Avoid using Teflon or any other fluoropolymer materials.

    • Use a trip blank to check for contamination during transport.

    • Do not mix up caps and bottles.

  4. Documentation:

    • Properly label each sample with the collection date, time, and location.

    • Complete all necessary forms accurately.

  5. Transport:

    • Store samples in PFAS-free containers.

    • Keep samples cool and deliver them to the lab promptly.

Detailed Instructions for PFAS Sample Collection

1. Equipment Preparation:

  • Use only approved, PFAS-free materials for sample collection.

  • Ensure all bottles and caps are clearly labeled and do not get mixed up.

  • Verify that sample bottles contain the necessary preservatives; avoid overfilling and do not pour out any liquid.

2. Sample Collection:

  • Raw Water Sample: Collect from a location before any water treatment system, typically directly from the well.

  • Treated Water Sample (POE): Collect from the point where water enters the distribution system after any treatment or pressure tank.

  • Pressure Tank Sample: If applicable, take a sample directly from the pressure tank.

3. Handling Samples:

  • Always wear new nitrile gloves when collecting samples.

  • Use a fresh set of gloves for each sample to prevent cross-contamination.

  • Avoid using any materials containing Teflon or other fluoropolymers during the sampling process.

  • Include a trip blank to check for contamination during sample transport.

4. Documentation and Labeling:

  • Label each sample container with the collection date, time, and specific sampling point.

  • Fill out all required forms with accurate and detailed information.

5. Transporting Samples:

  • Store samples in PFAS-free containers to prevent contamination.

  • Keep the samples cool, ideally by using ice packs, and transport them to the certified lab as soon as possible to ensure the integrity of the samples.

Understanding Water Sources

  • Raw Water: Water collected directly from the well before it goes through any treatment processes.

  • Treated Water (POE): Water that has been treated and is collected at the point of entry to the home's distribution system.

  • Pressure Tank: A tank that maintains water pressure in a private well system; samples may be taken here to assess the quality post-pressure but pre-distribution.
