Arsenic levels in drinking water must drop to 10 ppb by 2006. What does this mean to the water service industry?
Most recently, in the waning days of the Clinton administration, the Environmental Protection Agency posted a rule that lowered the more than half-century-old standard to 10 ppb. Not long after, though, on March 22, 2001, under the new leadership of the Bush administration, the EPA withdrew the rule, citing the need for additional research on cost and health effects.
