Synthetic DNA tracers are gaining interest as tools for tracking contamination pathways and hydraulic connections in surface water and groundwater systems. However, few quantitative data exist that describe DNA tracer degradation and adsorption in en

Publikováno v: Journal of Hydrology. 558:55-71

A test using Rhodamine WT and heat as tracers, conducted over a 78 day period in a strongly heterogeneous alluvial aquifer, was used to evaluate the utility of the combined observation dataset for aquifer characterization. A highly parameterized mode

Point-of-use filters are the major means of treating household drinking-water from non-reticulated water supplies, especially in developing communities, but their effectiveness at removing protozoa varies greatly. We custom built a full-scale filter

Open framework gravels (OFGs) are an inherent textural component of alluvial gravel outwash deposited by braided river systems. Being exceptionally permeable, they play an important part in facilitating the transmission of water and contaminants thro

Publikováno v: Journal of Contaminant Hydrology. 191:19-32

Reducing conditions are necessary for denitrification, thus the groundwater redox status can be used to identify subsurface zones where potentially significant nitrate reduction can occur. Groundwater chemistry in two contrasting regions of New Zeala
