*Title

Biological and Environmental Sampling of Per- and Polyfluoroalkyl Substances (PFAS)

*Description

A statistically based, community sampling design will be used to determine

• PFAS serum concentrations from participants living in communities with exposures to PFAS in drinking water.

• PFAS urine concentrations from a subset of participants living in communities with exposures to PFAS in drinking water.

  • An initial 10% of urine samples will be analyzed for 18 PFAS and creatinine. Additional analytes may be added should methods become available. If the geometric mean PFAS concentrations in this initial subset are elevated compared to the U.S. national reference population, as defined by the 2013-2014 NHANES 95th percentile, all other urine samples from the site will be analyzed.

• PFAS concentrations in indoor dust and tap water samples from a subset (10%) of homes of participants in biological sampling.

A questionnaire will be administered to all participants to gather information that can be used to characterize each individual’s exposure.

The collected data will be analyzed to determine PFAS blood levels for individual participants as well as the community as a whole. Serum and urine concentrations will be compared to reference ranges from nationally representative data, and correlations between environmental and biological PFAS concentrations will be evaluated.

☐ Restricted access data sharing

(Dataset is only available in an RDC; data need to remain under CDC custody.)

Justification (required if selected):

No Data Release/Sharing

☐ No release or data sharing

Justification (required if selected):

Access Rights/Restrictions

Justification: (provide detailed information about the data category selected above. If D6 is selected, provide quantitative estimates of costs in releasing data and expected volume of use. If D7 is selected, specify the reason that prevents the owner from releasing/sharing the data.)

Data will be collected by a contractor or cooperative agreement partner funded by CDC/ATSDR.

Population Represented

(e.g., “residents of x,” “inpatients at x,” “users of product x”)

TBD – Residents of no fewer than eight communities with PFAS contaminated drinking water. Exact locations to be determined.

Data Collection Protocol

(Brief description with reference to document or website that provides detailed information.)

Participants in each exposure assessment will complete consent/assent/parental permission forms, provide blood and urine samples and respond to a questionnaire at a centralized location in the community. Participants will be responsible for collecting first morning urine samples in their homes and transporting them to the centralized blood collection location. A subset of participant households will be randomly selected for environmental (i.e., indoor dust and tap water) sampling. Administration of consent forms for environmental sampling and indoor dust and tap water sample collection will take place during a home visit.

All blood samples will be shipped to the NCEH laboratory for analysis of PFAS concentrations and then shipped to a bio-specimen repository for storage. A subset of urine samples will be shipped to the NCEH laboratory for analysis of PFAS concentrations. The remaining urine samples will be shipped to a bio-specimen repository for storage. Drinking water and indoor dust samples will be shipped to an EPA-accredited laboratory for analysis of PFAS concentrations and then stored.

Detailed data collection procedures are available in the protocol for the assessments.

Data Management Protocol

(Brief description with reference to physical location(s) or system(s) where data will be housed (e.g., CDC shared network drive, data host system name, SQL database, etc.) and to data formats. Include the locations of dataset both before data release and after data release.)

All data will be transmitted to ATSDR or ATSDR contractor for incorporation into a centralized data management system. All results will be electronically transmitted in spreadsheet format using a secured and password-protected network.

All documents with personal identifying information (i.e., consent forms, assent forms, collection logs, etc.) will be kept in locked cabinets and all electronic data will be stored on a password-protected network servers behind firewalls, accessible only to those staff working directly with raw data.

De-identified samples will be sent to the laboratories—no individual identifiers will be included. Any reports produced from this information will not identify specific individuals.

Process for Omitting Identifying Information

(Description of what identifiers are in the database, how they will be removed, and by whom.)

All samples and data will be identified with a unique code and participant birth date only. Only the project coordinator will have access to the link between the sample identification code and personal identifying information in order to facilitate communication of individual results with participants.

Data Quality Protocol (to address issues of privacy protection and statistical stability)

(Brief description with reference to document or website that provides detailed information. Describe methods for data validation and error resolution, removal or shielding of any proprietary information, removal or shielding of sensitive information [i.e., data with dual use applicability], removal or shielding of any individually identifying information including indirect identification.)

All laboratory analyses will be conducted with established procedures for quality assurance and control according to NCEH and EPA protocols. These methods are identified in the protocol for the exposure assessments and are available from NCEH and EPA.

Data Retention/Disposal Plan

(State when and how the dataset will be archived or destroyed [in accordance with CDC/ATSDR Records Control Schedule: http://isp-v-maso-apps/RecSched/images/RCS.pdf ].)

Records will be retained and disposed of in accordance with the CDC Records Control Schedule. Physical copies of assessment materials and reports will be maintained at ATSDR until no longer needed by program officials and will be kept no longer than five years following completion of the exposure assessment in accordance with retention schedules. Computer documents will be disposed of when no longer needed by program officials and will be kept no longer than five years following the study. Personal identifiers will be deleted from records when no longer needed. Disposal methods will include erasing computer files, shredding paper materials, or transferring records to the Federal Records Center when no longer needed for evaluation and analysis. Records are retained for 20 years.

Data Analysis Plan

(Brief description of planned use of the data. Can include reference to document [e.g., information collection request, research protocol, or other] that provides more detailed information.)

Data will be analyzed for each individual participant and in aggregate. Detailed information is provided in the protocol.

Publication Plan

(Brief description of planned CDC-authored and CDC-coauthored publications, including topic, type of publication, and estimated timeline.)

Aggregate findings from the exposure assessments are expected to be published as ATSDR reports and in the peer reviewed literature. The topic of publications will be human exposure to per- and polyfluoroalkyl substances. Reports and publications are estimated to be released in 2020.

Data Release Documentation

(List documents provided to users, e.g., variable definitions, codebook, metadata file, guidance on data use.)

TBD

Data Release Format

(Recommend to use non-proprietary format when possible, such as CSV, JSON, etc. Also specify data dictionary file format.)
