Aging of biosolids in fields prolongs the release of biosolid-borne PFAS and promotes the release of select PFCA in water Aging of biosolids in fields prolongs the release of biosolid-borne PFAS and promotes the release of select PFCA in water
Land application of biosolids can introduce PFAS into croplands. Biosolids transported to surface waters through runoff may subsequently release PFAS into aquatic environments. The objective was to evaluate the effects of the aging of biosolids and the presence of sediment on the release of biosolid-borne PFAS to water at the water-sediment interface under anaerobic conditions. Through...
The effect of temperature, flow, density and disease on smallmouth bass (Micropterus dolomieu) early life growth rate The effect of temperature, flow, density and disease on smallmouth bass (Micropterus dolomieu) early life growth rate
Individual growth rates of fish are influenced by gradually changing environmental conditions and rapid-onset events. However, there is a paucity of information on drivers of spatiotemporal variability in growth rates of fishes across large spatial extents. Using a 36-year dataset of smallmouth bass (Micropterus dolomieu) length-at-age data across 10 river reaches in Pennsylvania, USA (n...
Non-destructive sampling of larval amphibians shows tail tissues reflect whole-body methylmercury concentrations and trophic-related differences in bioaccumulation Non-destructive sampling of larval amphibians shows tail tissues reflect whole-body methylmercury concentrations and trophic-related differences in bioaccumulation
Mercury (Hg), and specifically methylmercury (MeHg), is a contaminant of global concern to humans and wildlife, but there is still limited understanding of its effects on many taxa. Amphibians are closely associated with water, where Hg is converted to MeHg, and high concentrations of MeHg can reduce survival of amphibians in the wild. However, limited non-lethal proxies exist for...

New Jersey ScienceBase Catalog
Hydrologic data collection, processing, analysis, dissemination, and archiving are major parts of the New Jersey Water Science Center program. ScienceBase is a primary repository for USGS data releases, published USGS scientific data and metadata, presented in a structured, discoverable format.
Coastal Plain Chloride Network
Chloride levels in groundwater are measured in selected wells on a 5‑year cycle to provide early warning of saltwater intrusion and to delineate the 250 mg/L line of equal chloride concentration within the principal aquifers of the New Jersey Coastal Plain.
