MPART is implementing enhanced protocols (available here: MPART Continuity of Operations Plan for Residential Well Sampling Considering EO 2020-92) to prevent the spread of COVID-19 during resumed activities to identify and reduce exposures to PFAS in drinking water from residential wells.
- Protocols updated October 2020
PFAS sampling is different from other types of sampling because PFAS are present in many things we use in our everyday life, such as water-resistant and stain-resistant products. PFAS can also be present in:
Since PFAS are analyzed in such small quantities--parts per trillion--even the smallest cross-contamination could contribute to a false positive sample. To learn more about which products contain PFAS and which do not, review the General PFAS Sampling Guidance document, below. Then use the media-specific guidance document for the specific type of sampling you are interested in.
This document is intended for residents and homeowners to use when collecting their own sample to send to an environmental laboratory. Most laboratories will provide their own sample collection instructions. This guidance document may be used in conjunction with any sample collection instructions provided by the laboratory. This document does not supersede the laboratory’s sampling instructions.
The Residential Well Sampling Guidance for residents is also available at the Home Sampling Guidance page, along with information about Laboratories Offering Home Testing.
