Incorporating spatial variability into GIS to estimate nitrate leaching at the aquifer scale
Date of Original Version
The effect of spatial variability of selected intrinsic soil properties and extrinsic management practices on the groundwater quality in the 330-ha recharge area of a high yield well site in Rhode Island is evaluated. A mass balance model that relates leaching from the vadose zone to long-term estimates of NO3-N concentration at the well is used. A GIS database and stratified sampling for both soil characterization and assessment of spatial variability of NO3 leaching are used. It is shown that GIS data bases generated at scales available to resource managers may be well suited to manage the water quality of large production scale wells.
