Less than three months after the January 2006 deadline for public water systems to make operational changes to comply with the 10 ppb MCL for arsenic, the U.S. EPA is proposing a revision. The revision would allow systems serving 10,000 or fewer residents to have as much as 30 ppb of arsenic, three times the level of contaminants allowed under the new regulations.
The proposed revision is a direct response to complaints by small communities that cannot afford to comply with the new limit.
