The goal of the ESER offsite surveillance program is to monitor several different media points within these potential pathways, including air, water, foodstuff, and soil, that could potentially contribute to the dose received by the public. 

Air samples are taken at 15 locations on and around the  INL surface water at five locations on the Snake River; drinking water at 14 locations around the  INL foodstuff which includes milk at nine dairies around the  INL potatoes from at least 5 local producers, wheat from approximately 10 local producers, lettuce from approximately nine home-owned gardens around the  INL sheep from 2 operators which graze their sheep on the  INL and various types of wildlife including big game (pronghorn, mule deer, and elk), waterfowl, and fish sampled on and near the  INL..
