locations and circumstances of any such elevated levels. These we cnn cate ll samples will be analyzed on a priority basis so that results can be reviewed by the Data Evaluations Group early in the study. These evaluations will be used to decide on any adjustments in the air sampling program design and scope which can be proposed to the Technical Director for implementation, 2, Biota Sampling . The terrestrial food-chain team will.focus their effort on obtaining samples of arrowroot, pandanus, coconut, crabs, birds and such other plant cw Meee Meee en at epee atin ence t and animal organisms as may constitute the diet of future inhabitants. The edible vegetation samples will be collected as available and in conjunction with appropriate soil samples. Edible animal species will be collected as available by trapping or shooting. Inedible plant species to be used as indicators for soil-root-plant pathways will be collected with the soil survey group. At least two or © three species that occur on all islands will be used for this purpose in order to obtain comparative data. Samples of these will be collected on the lagoon side, ocean side, and in the central parts of each island at we points where soil samples are collected. These will be returned to the Eniwetok laboratory for identification and processing. Rats, which are not considered to be a part of the human food chain, are the only mammals existing on the islands and may.be considered as an indicator species, These will be trapped and specific organs will be analyzed for radioactivity. Collection sites for all specimens will be identified on the radiological survey maps for later correlation. 3. Potable Water The only potable water on the Atoll is derived either from rain water or the distillation plant on Eniwetok,. Samples of these will be collected for radiochemical analysis along with sludge samples from the distillation plant. In addition, a marginal lens exists on Engebi which we plan to sample. 4, Onsite Laboratory at Eniwetok An onsite laboratory will be established on Eniwetok for processing samples obtained by the biota field tesms, This will include; forced draft ovens for drying plant material for shipment; dissecting equipment for AE caer separating organs from animal species, and counting equipment screening of specimens before they are returned to LLL. ~20- The principle equipment to be : ‘
