Water Targets in Hawaii

Preparation and placement of ultraclean water targets along altitude transects in Hawaii for research on beryllium recovery. Utilizes acidic leached HDPE carboys provided by NSF/SRC Center for Environmentally Benign Semiconductor Manufacturing. Water treated with UV for TOC reduction. Research conducted at the University of Arizona's clean room facility.

  1. Water Targets in Hawaii Prepared 80 carboys of ultra clean water Placed carboys along an altitude transect in Hawaii Retrieved 1 set of carboys for Be recovery testing (in progress) Approx. 1.5 yr of exposure remaining

  2. Water Targets - Preparation • Prepared 1.5 Metric Tons of 18.2 MWater in Acid-Leached HDPE Carboys • Provided by NSF/SRC Center for Environmentally Benign Semiconductor Manufacturing (fabrication water) at U of A • Includes UV treatment for TOC reduction and disinfection • < 1 ppb TOC • All trace metals including Be are below 2.5 ppt detection limit of ICPMS Clean room: NSF semiconductor fabrication center for ultra pure water, University of Arizona
