EPA Method 218.6: Low Level
Hexavalent Chromium

Savannah Laboratory

Method Application:

This method is used to determine Hexavalent Chromium (Low Level), intended for aqueous drinking water and groundwater samples. The Savannah laboratory can report a detection limit of 0.02 parts per billion (ppb).

Market Application:

This method is designed for State drinking water agencies and public water system (PWS) owners who are required to test for Low Level Hexavalent Chromium in drinking water.

In September 2010, the U.S. EPA released a draft of their Toxicological Review of Hexavalent Chromium  for public review and comment. The human health assessment is projected to be finalized in 2011, in which the EPA will carefully assess relevant conclusions to determine if a new Agency policy needs to be implemented. Recent studies indicate that the potential for human health risks from chromium-6 is greater than previously considered.

Advantages:

The EPA is providing interim guidance to water systems on how they may monitor for chromium-6 and total chromium. This method provides an enhanced determination of Hexavalent Chromium at Health Risk-Based Levels in drinking water.
