Groundwater Protection and Unconventional Gas Extraction: The Critical Need for Field‐Based Hydrogeological Research
TL;DR: Two areas are identified where field-focused research is urgently needed to fill current science gaps related to unconventional gas extraction: baseline geochemical mapping and field testing of potential mechanisms and pathways by which hydrocarbon gases, reservoir fluids, and fracturing chemicals might potentially invade and contaminate useable groundwater.
An artificial sweetener and pharmaceutical compounds as co-tracers of urban wastewater in groundwater.
TL;DR: The benefit of applying a suite of tracers to urban groundwater affected by wastewater contamination is demonstrated, and this approach should be applicable at other urban sites.

TL;DR: In this paper, the authors examined a suite of major ions and trace organic constituents within a well defined septic system plume in southern Ontario, Canada (Long Point site) for their potential use as wastewater tracers.

Residues of the herbicide glyphosate in riparian groundwater in urban catchments
TL;DR: Glyphosate and AMPA were detected in shallow riparian groundwater at 4 of 5 stream sites in urban catchments in Canada and each were found in approximately 1 in 10 of the samples overall, suggesting that the AMPA is derived mainly from glyphosate degradation rather than from wastewater sources.

The Radial Diffusion Method: 1. Using intact cores to determine isotopic composition, chemistry, and effective porosities for groundwater in aquitards
TL;DR: In this article, a new method is described for the determination of the isotopic composition and chemistry of groundwater in aquitards, based on diffusive exchange of water and solutes between groundwater in a cylindrical core of aquitard material and water in a reservoir placed along the axis of the cylinder.
