New Report: “Hawaiian Islands Soil Metal Background Evaluation”Posted on May 1, 2012 in All, Cleanup Highlights
The Hawaiian Islands background metals study has been in progress for several years and incorporates soil sample data from several technical and scientific sources. This report presents an evaluation of naturally occurring background concentrations of metals and related elements in the volcanic soils of the seven main Hawaiian islands (Kauaʻi, Oʻahu, Molokaʻi, Lānaʻi, Maui, Kahoʻolawe, and Hawaiʻi Island). Soil sample data were evaluated using cumulative probability plots, spatial and soil type distribution univariate plots, detailed spatial analysis, elemental association, geochemical analysis and professional judgment to estimate Hawaiʻi-specific background concentration ranges.
For more information on the report see the cover memo.
