OVERVIEW

Hexavalent chromium (Cr (VI)) is a widely recognized carcinogen. As a result, the California Department of Public Health (CDPH) has started to regulate Cr (VI) in drinking water by setting a maximum contaminant level (MCL) of 10 ppb.

Due to this new regulation, Babcock Laboratories runs U.S. EPA Method 218.7 using the Thermo ScientificTM DionexTM ICS-1100 system to determine Cr (VI). Based in Riverside, CA, Babcock Laboratories is an environmental lab that provides high quality chemical testing services for customers ranging from large corporations to individual property owners. They are dedicated to helping their customers meet requirements for state and federal regulations.

This webinar will discuss current Cr (VI) regulations for water testing, summarize U.S. EPA Method 218.7 for compliance testing and review the chemistry involved with sample preservation.

KEY LEARNING OBJECTIVES:

- Learn about current regulations for Cr (VI)

- Learn about the chemistry of U.S. EPA Method 218.7 for determining Cr (VI) in drinking water

- Learn about the different oxidation states of chromium and understand the importance of sample preservation

WHO SHOULD ATTEND
  • • Environmental/water testing labs or water districts that perform Cr (VI) testing in drinking water
  •  
  • • Labs that run U.S. EPA Methods 218.6 and 7199 who are also interested in U.S. EPA Method 218.7
  •  
  • • Researchers interested in current and expected Cr (VI) regulations
