Where is Groundwater Most Vulnerable?

  • The vulnerability of groundwater to contamination from the surface is controlled in large part by the speed and length of the infiltration pathways.
  • Highly permeable soils allow surface contaminants to migrate more quickly into the subsurface, while porous soils slow the infiltration of contaminants.
  • This map shows areas of the state which are most at risk of contamination.  The red areas represent highly permeable soils which overlay permeable rock types.
  • Many activities pose a potential risk to groundwater contamination.

  • Activities that occur in the home, on the farm and in the field have the potential to contaminate our groundwater supplies.  Information contained in the Farm*A*Syst, Home*A*Syst and Field*A*Syst educational packets will help you to understand how you can protect the quality of your drinking water.
