| Arsenic in Ground Water: Characterization and Treatment | |||
| The arsenic regulation that was promulgated in January 2001 with a compliance date of January 23, 2006, lowered the arsenic concentration from 50 ppb to 10 ppb. This regulation has presented a variety of technological and economic challenges. Abstracts on innovative technologies and approaches to meeting the standard, including performance and cost, are encouraged. | |||
