Yesterday, the State Water Resources Control Board (SWRCB) Division of Drinking Water (DDW) issued a press release regarding new Response Levels (RL) for PFOA and PFOS.
The Response Level for Perfluorooctanoic acid (PFOA) is now set at 10 parts per trillion (ppt)
The Response Level for Perfluorooctanoic sulfonate (PFOS) is now set at 40 ppt.
Previously California RL’s were set at the federal level of 70 ppt for PFOA and PFOS combined.
Babcock Laboratories currently has established laboratory Method Detection and Reporting Limits for 537.1 analytes well below the new Response Level limits.
