Contamination in the Northern Great Plains aquifer system is a concern. There is a shortage of the amount of freshwater that is taken from the aquifers. Freshwater is considered to have less than 500 milligrams per liter of dissolved solids. In some areas, water is used for human consumption that has dissolved solid concentrations over 2000 milligrams per liter. The reason for this is because of the lack of fresh water. The main sources of contamination come from agricultural fertilizers and pesticides. Many of the Northern Great Plains aquifers are affected by these chemicals through their recharge processes. The shallower aquifers are particularly affected because of the lack of time that the contaminant has to be absorbed. Point source contamination is also a problem in this region. Petroleum spills is often times a problem due to underground storage tank spills (USGS, 2005a).
