Tuesday Trivia – Answer for November 27, 2018

Just a reminder that last week’s post focused on PFC compounds in drinking water. Read below to see whether your answers match mine!

The U.S. EPA uses the Unregulated Contaminant Monitoring Rule (UCMR) to better understand the prevalence and potential toxicity of contaminants that they suspect might be present in our drinking water. Once every 5 years, the EPA publishes an updated list of contaminants that have to be monitored by public water systems.

Under the requirements of the Safe Drinking Water Act (SDWA), each UCMR list can contain a maximum of 30 contaminants.

In May of 2012, the UCMR 3 list was published. That version of the list contained 6 perfluorinated compounds for monitoring. Four of those compounds were: PFOS, PFOA, PFHxS and PFHpA.

The other 2 compounds are:

PFNA
PFBS
