Food, beverage, and feedstock processing facility wastewater: a unique and underappreciated source of contaminants to U.S. streams

Process wastewaters from food, beverage, and feedstock facilities, although regulated, are an under-investigated environmental contaminant source. Food process wastewaters (FPWWs) from 23 facilities in 17 U.S. states were sampled and documented for a plethora of chemical and microbial contaminants. Of the 576 analyzed organics, 184 (32%) were detected at least once, with concentrations as large as

Integrated science for the study of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in the environment—A strategic science vision for the U.S. Geological Survey

Concerns related to perfluoroalkyl and polyfluoroalkyl substances (PFAS) in sources of drinking water and in natural and engineered environments have captured national attention over the last few decades. This report provides an overview of the science gaps that exist in the fields of study related to PFAS that are relevant to the U.S. Geological Survey mission and identifies opportunities where t

Simulation of potential water allocation changes, Cape May County, New Jersey

Saltwater intrusion and declining water levels have been a water-supply problem in Cape May County, New Jersey, for decades. Cape May County is surrounded by saltwater on three sides. Several communities in the county have only one aquifer from which freshwater withdrawals can be made, and that sole source is threatened by saltwater intrusion and (or) substantial declines in water levels caused by

Baseline Water-Quality Inventory for Paterson Great Falls National Historic Park, New Jersey

The Paterson Great Falls National Historical Park (PAGR) in the historic city of Paterson, New Jersey was established in 2011 and consists of natural, cultural, and historic resources associated with the Great Falls of the Passaic River. Due to the park’s young age and limited resources, the park does not have the natural resource data needed to guide future park management and planning decisions...

A Field Method to Quantify Chlorinated Solvent Diffusion, Sorption, Abiotic and Biotic Degradation in Low-Permeability Zones

Strategic Environmental Research and Development Program project ER-2533 In chlorinated-solvent-contaminated fractured-sedimentary-rock aquifers, low-permeability (low-K) strata typically act as long-term or secondary sources of contamination to mobile groundwater in the high-permeability fractures. The fate of dissolved trichloroethene (TCE) in the low-K matrix is controlled by abiotic...

Coastal Plain Aquifer Synoptic - Chloride Network

Chloride concentrations in groundwater are measured in select wells on a 5-year cycle, as an early warning indicator of saltwater intrusion, and for the definition of the 250 mg/L chloride concentration line within the principal aquifers of the New Jersey Coastal Plain.
