Title: GIS Wellhead Project

2PHS Wellhead Project
- Purpose
- Collect test results from nitrate clinics
- Test nitrate levels in ground water below
agricultural fields - Inform the public about nitrate levels in their
drinking water. - The GIS class has a website for the Perham
Wellhead Project, with information on what
nitrates are and how they get into your ground
water. The website also contains power point
presentations that our group and previous groups
have created. - Input data from nitrate clinics into Arc View
GIS - Using GIS, we can plot these points on a map of
the Perham area, allowing us to see where the
results came from. The program also allows us to
do queries, to find more narrowed results. We can
make very narrowed results by asking for places
with specific things such as We can find places
where the nitrate level is greater than ten and
has a feed lot within 100 feet of their well.
3The Yellow dots are the homes that have a nitrate
level of greater than 10 parts per million and a
feed lot within 100 feet.
4People that live in the country with a reverse
osmosis system are the yellow dots.
5The yellow dots are wells with nitrate levels
less than 10 parts per million. Water with less
than 10 ppm is safe for drinking.

- Our group out in a potato field collecting
data with Carl from the University of Minnesota. - In the picture we are weighing a bucket of
sample potatoes, that will go back to the lab and
be tested for nitrate levels. To see how much of
the fertilizer the crop used and how much of it
leached into the ground water. -
