Preferential flow mechanisms : their interaction and effect on dye movement in till and glaciolacustrine sediment
<p>Contamination of groundwater by agricultural chemicals is of concern to the population of the Northern Great Plains. Preferential flow (macropore, finger, and funnel) allows such chemicals to move relatively rapidly through materials considered to be aquitards. Preferential flow mechanisms at …

A radiocarbon method and multi-tracer approach to quantifying groundwater discharge to coastal waters
Groundwater discharge into estuaries and the coastal ocean is an important mechanism for the transport of dissolved chemical species to coastal waters. Because many dissolved species are present in groundwater in concentrations that are orders of magnitude higher than typical river concentrations, …

Design and evaluation of a modified in situ mesocosm to study denitrification in the Karlsruhe aquifer
To simplify the in situ mesocosm (ISM) design given in Schlag (1999), a modified ISM was designed and built in which a 6-inch long sand point replaces three 16-inch diameter screens. The modified design also includes an optional submersible pump mounted on top of the ISM chamber, making it capable …
