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. EPA-certified laboratory, Envirotek Laboratories, Inc. 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. The results are summarized below: FILTERED WATER RESULTS Time Before Filtering MCHM concentration in Adya Clarity Filtered Water% Reduction 12 hours. 7.5 µg/L 94.4% 24 hours 3.5 µg/L 97.4% 48 hours.

Iron and Steel, ALEKSEY NIKALAYEVICH UVRANTSOV One of the oldest employees of the refractory industry, Alek~ey Eikolayevieh Uvrantsov, died o~ June 7, 1961 after a long a~d serious I l lness. Uvrantsov went to ~rk as the head of the planning secUon at the Tsemroshamot Trust in 1929. And for 30 years; up to his retlrcment: was engaged in planning and ftX~c~l ~oz'~ in the refractory i~tluslry. As a highly qua~fled specialist and a ma~ of great energy and lr, itiatJve, A.N, U~ra~Eov took an aeLive part In compiling current and long~ plans [or the de- velopment 9[:he refractor), indus,ry during the f irst Five~ Year Plans, daring the restoration of the refractory establishments after the 1941 - 1945 war, and also In the post-war years.

During his years of work h~ the refractory Ind~_~try, he ~s awarck-d four medals. Ap~ from his great work in industry, A.N. Uvran- ~ov ~ an ac~ve p~rt in social work, I~ 1945 he bec~ae a member of the Communist l~r ty.

The memory of A.N. Uvraatsov, an active participant in the development of the refractory industry and a worthy sen of the Party; a man of great personal qualifies, will never fade in the hearts of all those who knew hi~.
