Happy Tuesday! This week’s question will address perfluorinated compounds in drinking water. If you want to brush up on this topic, there’s a fantastic webinar you can stream, which presents challenges in extracting PFC compounds in drinking and wastewaters. If you feel that you’re a PFC expert, read on and test your knowledge!
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 _____(how many)_____ 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 ______(how many)_______ contaminants.
In May of ___(what year)____, the UCMR 3 list was published. That version of the list contained ____(how many)_____ perfluorinated compounds for monitoring. Four of those compounds were: PFOS, PFOA, PFHxS and PFHpA.
Can you name the other 2 PFC compounds?
Need a hint? They’re both perfluorinated compounds.
Need another hint? They’re both 4-letter acronyms that start with the letters “PF”
Submit your guess in the comments below and stay tuned for the answer next Tuesday!
