On
Feb. 2 the EPA announced a final regulatory determination for perchlorate in
drinking water. This announcement
from Lisa Jackson, Administrator for the US EPA, reversed a preliminary
determination in 2008 not to regulate perchlorate. With this action the EPA
initiated development of a national primary drinking water regulation (NPDWR)
that, once finalized, will require certain potable water suppliers to take
corrective action for high perchlorate levels. For more information on this
regulatory action, please visit

Dionex
has been at the forefront of collaborating with the EPA Office of Ground Water
and Drinking Water in Cincinnati, aiding in the establishment of EPA methods
314, 314.1, 314.2, 331, and 332 for determination of perchlorate. We recommend
EPA 314.0 for analysis of drinking water and the more robust 314.2 for source
waters with high amounts of chloride, carbonate, and sulfate.
