NAPRA?
Publications TMDL More Info |
NAPRA is the National Agricultural Pesticide
Risk Analysis (NAPRA) tool developed by the Natural Resources Conservation
Service, USDA. It provides an automated pesticide risk screening process
by using an environmental fate model GLEAMS (Groundwater Loading Effects
of Agricultural Management System). NAPRA can provide climate-based probabilities
of off-site pesticide loadings and concentrations. It assesses the risk
of pesticide loss from the bottom-of-the-rootzone and the edge-of-the-field,
which could potentially contaminate surface and groundwater. The risk is
rated according to the EPA drinking water standard. Implementing NAPRA requires
interdisciplinary technical support and a variety of data inputs. Several
counties are chosen as pilot study areas in implementing NAPRA process
in Michigan. NAPRA approach may help farmers identify
best management practices to reduce hazardous off-site pesticide losses.
Farmers and other potential users can get access to our NAPRA Web site via Internet. We hope this
web site may provide a convenient and efficient way to help extension personnal and farmers use
NAPRA technology to assess the potential risk of pesticides in the farmlands.
Five Michigan counties are chosen to represent different soils,
climate, and agricultural characteristics. These five counties are loacated in five most important agricultural districts in Michigan. NAPRA scenarios are available
for those Agricultural Districts with a selected county as the study area.
