The Pesticide Nitrate relation

The State DEEP has been saying for a long time that if a well had Nitrate nitrogen over 5.0 mg/L, the well should be tested for pesticides.
A while back i said that it did not look as if it was so, but was waiting to study it.
Here is the data

343 wells tested for both pesticides and Nitrate-nitrogen.
66 showed pesticides at some level.
45 showed Nitrate Nitrogen > 5.0 mg/L
11 wells with high Nitrate-nitrogen showed pesticides
55 did not.

Lets put the nails in the coffin, this does not correlate!
