The purpose of this study was, therefore, to document demographic characteristics of domestic well users in the LUB, and to evaluate whether or not this population is potentially at risk from drinking well water containing nitrate.
Individuals living in rural residences in the LUB who used private wells were surveyed by telephone to gather information about their water consumption practices.
Surveys were administered to 83 residences in the LUB area.
8% of the total LUB population, and approximately 0.
The majority of respondents (63%) had lived elsewhere in the LUB prior to moving to their current location.
Because shallow wells are generally more at risk of nitrate contamination than deep wells, well depth and nitrate concentrations were compared for 78 of the wells in the LUB survey area (12,13).
The median nitrate level for wells serving the surveyed LUB households (4.
The LUB survey findings were similar to those reported in an earlier study of well water nitrate in northern Malheur County, Oregon, where approximately 30% of the sites exceeded the 10 ppm nN MCL (1).
This study investigated the demographics of well water users in the rural LUB of Oregon, and compared these data to identified well water nitrate levels to evaluate whether or not this population is potentially at risk from drinking water from their wells.
