Managed aquifer recharge and changes in crop type or nutrient management on agricultural lands are promising approaches to address groundwater quality degradation by nitrate.
Nitrate in drinking water may cause serious health problems for consumers. Agricultural activities are known to be the main source of groundwater nitrate contaminating rural domestic and urban public water supply wells in farming regions.
CV-GNLM (Groundwater Nitrate Loading Modeling) and CV-SWAT (Soil & Water Assessment Tool) are two different approaches to estimate nitrate loading leaching rates to groundwater
After the water leaves the root zone, it percolates to the water table, mostly vertically down. From the water table it travels laterally and vertically through groundwater along groundwater flow paths.
At the core of our Nonpoint Source Assessment Tool (NPSAT) is software for the simulation of a high-resolution steady-state flow solution in an unconfined and variably confined aquifer system. We have developed our own, highly efficient numerical algorithm to accurately solve the groun
Assessing the impact of a land-use change (LUC) or the change in nutrient management practices on nonpoint source-driven groundwater quality requires complex analysis.
Degradation of groundwater quality due to nonpoint source (NPS) contaminants from the land surface, especially nitrate in agricultural aquifers, is a major environmental concern.
Non-point source (NPS) pollution has degraded groundwater quality of unconsolidated sedimentary basins over many decades. Properly conceptualizing NPS pollution from the well scale to the regional scale leads to complex and expensive numerical models:
