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.
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 groundwater flo
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:
