• • • • 1942: Federal government establishes an arsenic rule setting maximum contaminant level (MCL) at 50 µg/L (50 ppb). 1996: Congress directs EPA to set new standard by Jan. 1, 2000. 1996: EPA asks National Academy of Sciences (NRC) to study health effects. 1999: NRC recommends that EPA “significantly lower current standard” “as quickly as possible”. At 50 µg/L estimate a 1-in-100 chance of cancer. This is a problem, as the EPA usually is attentive to environmental risks at or below 1 in 100,000. Arsenic Rule: Timeline and Controversy Arsenic July 1, 2000: EPA proposes a preliminary rule – 5 µg/L July Jan. 22, 2001: EPA issues final rule – 10 µg/L Jan.
