All Community and Non-transient Non-community Public Water Systems in Idaho must comply with the new arsenic standard for drinking water.

Additional information on arsenic in drinking water can be found at the Idaho Department of Environmental Quality's Arsenic in Drinking Water site.

The deadline for compliance with the new arsenic standard is January 23, 2006. However, Idaho Public Water Systems that think they will be unable to meet this deadline may apply for an extension of compliance. Eligible Idaho Public Water Systems my be granted an additional three to nine years to comply with the new standard, depending on the number of people served by the water system and the arsenic concentration present in the system.

The Environmental Finance Center at Boise State University can assist Idaho Public Water Systems in making applications for a compliance deadline extension for the arsenic standard. Contact Bill Jarocki (208) 426-4293 at the EFC for more information.
