Below are examples of a spreadsheets created in Intellus, which is the environmental database at Los Alamos National Laboratory. The requests were for all soil and groundwater samples taken in, under, and around the Lab in 2021, 2022, and 2023. The spreadsheets were then sorted by “Report Result” (Column ‘F’), which lists the plutonium found in samples in descending order. It shows the highest sample for each year at top of the column.
Looking at the 2021 spreadsheet, there were 2043 samples analyzed for plutonium taken in 2021. There are approximately 100 detects including the high sample of 10100 pCi/g. Please read Dr. Ketterer’s report for a discussion of the ‘detects’ and ‘non-detects.’
Notice the latitude and longitude for each sample (columns ‘O’ and ‘P’). We used these coordinates to create the maps.
