PERHAM CITY WELL DATA
• Data indicating declines and at the very least stabilization…– As expected, declines in groundwater nitrate will
not happen as quickly as soil moisture levels

• The city negotiated a trade of other city owned land for ½ of the other pivot adjacent to the city limits.– Northern ½ will remain in
agricultural production for 10 yrs; after which time the owners agreed to take the land out of production
Within the past year…

Perham’s Story…...
• Nitrate levels stabilized/declined following two major changes – Alfalfa planting– Land Acquisition
• Area producers have been actively involved groundwater protection– Nitrogen fertilizer research– ESN on corn & potatoes since the early
2000s– Alternative varieties (Altura’s and Umatilas)– Nitrogen fertilizer BMPs
