In response to guidance released by EPA earlier this month, AMWA sent a letter to EPA Administrator Lisa Jackson, voicing its concern that the agency is recommending enhanced monitoring for hexavalent chromium (Cr-VI) without:
-
a clear understanding on proper analytical technique and whether the monitoring data will be valid given the method is not officially approved by the agency; and
-
a context for what monitoring results mean within the regulatory framework or how they relate to public health concerns.
The letter also asks EPA to disclose its timeframe for moving forward with the regulatory process outlined in the Safe Drinking Water Act (SDWA), since the Administrator has said that EPA is on an “expedited timeline” with regard to Cr-VI. Finally, the letter requests a meeting with the Administrator to further discuss the Cr-VI.
