Sample collections Water samples were colloctcd from the watcr supplics of all inhabiteo“ areas. About two quarts of water were transferred to a polycthlenc bottle at cach site, These will be turned over to the New York Operations Office, AEC -~ . analysis, S§odl samples were collccted at all inhabited arcas and also at severa:' uninhabited islands. In collocting tho soil samples a one foot by onc foct t square was markedon the ground and soil to about one inch of depth was removec from the square and transferred to a cardboard containcr. The primary samples will be turned over to the New York Operation Office, AEC, for analysis, and some smaller samples will be analyzed by Program 2 of TU 13, Listed in Table 3 are the samples taken with the doso ratc moasured .. at waist height at the location where they were takon.
