TL;DR: In this article, a conceptual model, developed by synthesizing the results of many researchers, which describes the geochemical evolution of domestic waste water in conventional on-site septic systems as the result of the interactions of a few major constituents.

TL;DR: The experiment indicates dissolved chlorinated solvent plumes from a residual dense non-aqueous phase liquid (DNAPL) source are likely to be highly mobile and persistent, at least in aquifers that are aerobic and have low sorption potential (low foc content).

TL;DR: In this paper, the results of a 72-day methane gas injection experiment into a shallow, flat-lying sand aquifer were presented, showing that even small volume releases of methane gas can cause extensive and persistent free phase and solute plumes emanating from leaks that are detectable only by contaminant hydrogeology monitoring at high resolution.

TL;DR: In this article, a bundle of polypropylene tubes contained inside a polyvinyl chloride (PVC) pipe that is installed in the aquifer is used as a point water sampler and piezometer.

TL;DR: The St Clair plain in southwestern Ontario is underlain by extensive clayey till deposits which are generally 30 m to 40 m thick as discussed by the authors, and most weathering features along fractures reach a depth of only 2.5 m to 4 m.
