Apply for a Voucher to Test Your Well

OHA is offering one testing voucher per well. Testing is an essential step in understanding if nitrate and other contaminants are affecting your well water quality and the action needed to reduce or eliminate your health risk from exposure to these contaminants.

You are eligible for a voucher if:

Your property well is located within the Lower Umatilla Basin Groundwater Management Area (LUBGMWA) of Morrow and Umatilla Counties. See map below.
Your well water is used for things like drinking, bathing, cooking and washing dishes.
Your well is not part of a public water system.

You will not be asked to share your US citizenship status in this application and your status does not affect eligibility to receive a voucher.
