Description
Estimating groundwater nitrate fate and transport is an
important task in water resources and environmental management because
excess nitrate loads may have negative impacts on human and
environmental health. With the joint support of FDEP and IESES, a
simplified nitrate transport model was developed. Computational implementation
of the model leads to a geographic information system (GIS)-based screening tool, whose purpose
is to estimate nitrate loads to surface water bodies from onsite
wastewater-treatment systems (OWTS). Key features of this software are
the reduced data demands due to the use of a simplified model, as well
as ease of use compared to traditional groundwater flow and transport
models, achieved by embedding the model within ArcGIS. The simplified
conceptual model consists of a simplified groundwater flow model in the
surficial aquifer, and a simplified transport model that makes use of
an analytical solution to the advection-dispersion equation, used for
determining nitrate fate and transport. Denitrification is modeled
using first order decay in the analytical solution with the decay
constant. The
groundwater flow model uses readily available topographic data to
approximate the hydraulic gradient, which is then used to calculate
seepage velocity magnitude and direction. Load calculations are carried
out using a mass balance approach where the system is considered to be
in the steady state.
