Through testing conducted by an independent, U.S. EPA-certified laboratory, it was determined that Adya, Inc.’s water purifying solution, Adya Clarity, reduces up to 99.9% of the chemical 4-Methylcyclohexanemethanol (MCHM) from water. The chemical, 4-Methylcyclohexanemethanol (MCHM) was spilled into the Elk River just upstream from the Kanawha County municipal water intake in Charleston, West Virginia on January 9, 2014, contaminating the water supply to over 300,000 West Virginia residents.

Of Mullica Hill, New Jersey, conducted the MCHM Reduction Test using Adya’s water purifying solution, Adya Clarity.
The following procedures were performed: Three liters of tap water were spiked with 400 μg of 4-Methyl-1-cyclohexanemethanol (MCHM) in a flask. Added 12 mL (4mLper liter) of Adya Clarity solution to the spiked solution, the flask was closed, mixed well and let sit for 12, 24, and 48 hours inside a fume hood. One liter of the solution was filtered through a 0.45 micron paper after 12 hours, a second liter of the solution was filtered through a 0.45 micron paper after 24 hours, the final liter of the solution was filtered through a 0.45 micron paper after 48 hours, the initial spiked solution and the filtered solutions were tested following the EPA method 525 for drinking water.
