Nitrate in shallow groundwater after more than four decades of manure application Open
Over-application of manure to agricultural fields can leach nitrogen below the root zone and contaminate groundwater. The goal of this study was to evaluate the factors affecting the spatial and temporal distribution of nitrate in shallow …

Removing the effects of temperature on electrical resistivity tomography data collected in partially frozen ground: Limitations and considerations for field applications Open
Time‐lapse electrical resistivity tomography (ERT) can be used to image a wide variety of subsurface processes. It is often necessary to remove the effects of seasonal near‐surface temperature variability in order to interpret the signal o…

Dual‐permeability modeling of preferential flow and snowmelt partitioning in frozen soils Open
The infiltrability of frozen soils modulates the partitioning of snowmelt between infiltration and runoff in cold regions. Preferential flow in macropores may enhance infiltration, but flow dynamics in frozen soil are complicated by soil h…

Current practices in private water well management in Rural Central Alberta Open
Approximately 238,000 to 450,000 Albertans rely on private water wells for their water needs. In Canada, private well owners are responsible for monitoring and maintaining the quality of their water well, yet studies in Alberta indicate th…

Effects of preferential flow on snowmelt partitioning and groundwater recharge in frozen soils Open
Snowmelt is a major source of groundwater recharge in cold regions. Throughout many landscapes snowmelt occurs when the ground is still frozen; thus frozen soil processes play an important role in snowmelt routing, and, by extension, the t…

Quantification of Groundwater Nitrate Loading after Raspberry Field Renovation Using High‐Resolution Passive Diffusion Sampling Open
The Abbotsford‐Sumas Aquifer is a permeable, unconfined aquifer in British Columbia, Canada, where raspberry ( Rubus idaeus L.) production is an important source of groundwater NO 3 contamination. Renovation of raspberry fields (i.e., cane…

Escherichia coli contamination of rural well water in Alberta, Canada is associated with soil properties, density of livestock and precipitation Open
Waterborne outbreaks of infectious disease continue to be a public health risk, particularly those in areas where testing of private and public small system groundwater systems is left to the owners/overseers of these wells who may not rec…

Electrical Resistivity of a Partially Saturated Porous Medium at Subzero Temperatures Open
Core Ideas We collected resistivity data at a range of temperatures and initial saturations. Archie's equation was modified to include temperature dependence below 0 ° C. Bulk resistivity was used to estimate unfrozen water content and flu…

Quantifying Nitrate Leaching under Commercial Red Raspberry Using Passive Capillary Wick Samplers Open
Core Ideas NO 3 leaching was quantified by passive capillary wick samplers over 2 yr. NO 3 leaching was three times greater in Year 1 than Year 2 (240 vs. 80 kg N ha −1 ). Increased Year 1 NO 3 leaching reflected field renovation prior to …

Snowmelt Infiltration and Macropore Flow in Frozen Soils: Overview, Knowledge Gaps, and a Conceptual Framework Open
Core Ideas Review highlights the hydrological importance of macropore flow in frozen soils. Governing flow mechanisms and infiltration and refreezing dynamics are discussed. Research is needed to integrate macropore flow and soil freeze–th…
