Event Description
In April 2024 US EPA finalized the National Primary Drinking Water Regulations (NPDWR) Maximum Contaminant Levels (MCLs) for PFOA, PFOS and four other PFAS. It includes complicated requirements we’ve never had in water regulation before, including the Hazard Index MCL and Trigger Levels to determine if a system may go on a reduced monitoring schedule.
Along with :
Is PFAS Sample Cross-contamination Caused by Sampling?
PFAS are prevalent in numerous items used when taking samples for laboratory testing. This, coupled with the fact that laboratories calibrate instruments to detect PFAS in the single digit ppt range, has led to a great deal of concern about the potential for cross-contamination of samples caused by sampling. Numerous PFAS sampling SOPs call for significant measures not required when sampling for other regulated contaminants, as well as more field QC samples. Is all this concern warranted? During this presentation attendees will learn about the incidence rate of cross-contamination in field QC samples from a recent and large set of samples taken from around the country.

UCMR 5 – What The PFAS and Lithium Data Reveals and What are Its Implications?
We now have about two years of UCMR 5 data accumulated from thousands of the nation’s public water systems. This data provides ample clues to US EPA’s potential inclusion of additional PFAS in Health Advisories and additional Maximum Contaminant Levels. In addition to monitoring for 29 PFAS, testing for Lithium is required and this data indicates widespread levels above EPA’s Health Reference Levels.
