Lake-bottom sediment and associated quality-control samples were collected in August 2020 from one coring location (U.S. Geological Survey station 413756070321301, ASHUMET POND, MASHPEE MI-ASHPD-0011) in Ashumet Pond downgradient from a former fire-training area on Cape Cod, Massachusetts. The core was collected to determine if per- and polyfluoroalkyl substances (PFAS) were present in the bottom sediments of a lake known to have elevated concentrations of PFAS in surface water and groundwater (Tokranov and others, 2021), and whether the sediments could act as a continuous source of PFAS to the lake. Processing the sediment core entailed collection of discrete samples at intervals ranging from 1-5 centimeters (cm)...

This data release is a revision of the USGS National and Global Oil and Gas Assessment Project-Southeast Asia Assessment Unit Boundaries and Assessment Input Forms data release (DR-P9BI2N1N). Like DR-P9BI2N1N, this data release contains the boundaries of 48 assessment units and their respective assessment input forms and data. In addition, this data release contains the assessment results data, thereby placing all the information related to the assessment of undiscovered oil and gas resources in Southeast Asia in one publication. The results table in this data release is the source data for the assessment results found in Table 1 of FS 2020-3046. The Assessment Unit is the fundamental unit used in the National and...

This data release includes concentrations of 24 per- and polyfluoroalkyl substances (PFAS) and physical properties of water-quality samples collected by the U.S. Geological Survey (USGS) at 64 selected sites in rivers and streams in Massachusetts over three rounds of sampling. The samples were collected from August to November 2020 when streamflow conditions were below normal (also considered to be base-flow conditions) at rivers and streams in urban areas that receive treated wastewater from municipal wastewater-treatment facilities, and in rural rivers and streams that are not associated with municipal wastewater discharges and may have other source inputs of PFAS. The measured physical properties include water...
