Award recognizes work on Michigan oxidation treatment system
Pall Corp. received an Outstanding Ground Water Project Award from the National Ground Water Association (NGWA) for outstanding science, engineering and innovation in the area of remediating groundwater. Pall designed, built and operates one of the world’s largest oxidation treatment systems for the destruction of 1,4-dioxane in groundwater. The system can pump and filter over 2 million gal of water per day.
The award will be presented at the 2010 NGWA Ground Water Expo and Annual Meeting in Las Vegas on Dec. 8. The award-winning project started in 1997 within months of Pall’s acquisition of Gelman Sciences Inc. (GSI), and continues today.
GSI used 1,4-dioxane from approximately 1966 to 1986 at its Ann Arbor, Mich., manufacturing facility. 1,4-dioxane, a common industrial chemical, is frequently used as a stabilizer and solvent. It also is found in personal care products such as shampoo, toothpaste and moisturizers. The wastewater disposal practices used by GSI at the time had the necessary regulatory approvals.
"Pall Corporation is honored by the NGWA's recognition of our efforts,” said Saied Tosi, senior vice president at Pall. “We are especially pleased that the knowledge gained from this project has already become, and will continue to be, a resource for others managing the same contaminant."
“Pall’s remediation project is praiseworthy for its effectiveness in attacking large scale contamination of 1,4-dioxane,” said NGWA President Jack Henrich. “The ‘persistence’ of 1,4-dioxane in this case is exceeded only by the ingenuity of the award-winning technology to remediate groundwater and Pall’s demonstrated commitment to this complex issue.”
