Arsenic Solutions
Arsenic is a grayish metalloid with atomic number 33 and an atomic weight of 75 amu. When dissolved in water, it is colorless, odor free, and can kill in small doses. Arsenic has been found in drinking water in several parts of the world including the US. The proposed arsenic standard of 10 ppb goes into effect in January 2006. As we try to find cost-effective solutions to this serious problem, I welcome any comments you might have on this subject.
