PHS 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.

The Yellow dots are the homes that have a nitrate
level of greater than 10 parts per million and a
feed lot within 100 feet.
4
People that live in the country with a reverse
osmosis system are the yellow dots.
5
The 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.
