Polycyclic aromatic hydrocarbons (PAHs) in the San Lorenzo River, Santa Cruz, California, USA, from 2015 to 2016

공공데이터포털

Polycyclic aromatic hydrocarbons (PAHs) are reported for water samples collected from the San Lorenzo River water during the rainy seasons from 2015 to 2016. Samples were collected during 2-, 5- and close to 10 year flood events.

Parent and alkylated polycyclic aromatic hydrocarbons (PAHs) and per- and polyfluoroalkyl substances (PFAS) in north San Francisco Bay, Napa River, and Sonoma Creek in 2018 and 2019

공공데이터포털

Sediment grain-size distributions, stable carbon isotope ratios (d13C), total carbon to total nitrogen ratios (C:N), short-lived radionuclides (Beryllium-7, Cesium-137, and Lead-210), concentrations of 76 parent and alkylated polycyclic aromatic hydrocarbons (PAHs) and concentrations of 33 per- and polyfluoroalkyl substances (PFAS) were measured in the northern reach of San Francisco Bay (San Pablo and Suisun Bays), and in stream beds of the lower reaches of Napa River and Sonoma Creek, 5 months and 20 months after the 2017 Atlas and Nuns wildfires. New sites for sediment geochemistry analyses added 20 months post-fire included the lower reaches of Petaluma Creek and Suisun Slough, and in marsh sediment on Napa River and Sonoma Creek.

Polycyclic Aromatic Hydrocarbons (PAHs) in Parking Lot Dust and Pavement Runoff Receptor Sites in Augusta, Maine

공공데이터포털

The dataset includes results from the analysis of sediments and solids collected from receptor sites receiving runoff from adjacent parking lots and other paved surfaces. Receptor sites include parking lot catch basins, retention ponds, drainage ditches, and storm-water discharge zones in streams and rivers. Samples were analyzed for percent moisture content and concentrations of 17 U.S. Environmental Protection Agency Priority Pollutant Polycyclic Aromatic Hydrocarbons (PAHs). Samples collected from parking lot sweepings (dust) also were analyzed for the same suite of 17 PAH compounds.

Per-and polyfluoroalkyl substances and polychlorinated biphenyls in influent, effluent, and biosolids samples collected from municipal wastewater treatment plants of the Patapsco and Potomac watersheds, 2021-2023

공공데이터포털

This metadata record consists of 3 tables containing per-and-poly-fluoroalkyl substances (PFAS) and polychlorinated biphenyls (PCB) concentration data of wastewater and biosolid samples from wastewater treatment plants within the Patapsco and Potomac watersheds. The PCB concentration data was used to assess the occurrence and fate of PCB in wastewater treatment plants within the Patapsco watershed, from December 2021 to December 2022; The PFAS concentration data was used to assess the occurrence and fate of PFAS within the Patapsco and Potomac watersheds, from 2021-2023. The PFAS total oxidizable precursors (TOP) assay data were used to investigate PFAS fate in the wastewater treatment process of plants within the Patapsco watershed from March and September of 2022.
